Modern way to steal a car

[bobthehobbyguy]

Just goes to show the more more complicated cars have gotten have made them easier to steal.

Which all just goes to show how really stupid the concept of using the CAN bus to link every electrical component in a car is.

Simple systems like lighting, the horn, power windows, wipers, and others can function perfectly fine as stand-alones...but today's insane obsession with making every dammed thing as complicated as possible refuses to acknowledge that.

The KISS concept is a thing for a reason.

EDIT: I was really glad to see the fellas who liberated that poor oppressed vehicle were being socially responsible and wearing masks, too.

call me old school, i still prefer a brick and screwdriver.....

 

 

 

more info:- i worked in a body shop and people dont take the keys out of the ignition when they drop them off so i learned lots of other ways too. for example a ford modeo/contour can be totally unlocked with a half tennis ball or you can bend the top of the door out far enough to reach in if the glass is fully up, and one good jerk of the steering wheel deactivates the steering lock so its just the old fashioned connecting wires then, vauxhall corsa could be started with a two bits of fairly stiff wire and there even a guide now on youtube on how to steal a kia or hyundai with an hdmi lead. and almost every old mini can be started with any worn key of the same style. Theres loads of others for current cars but for obvious reasons i'm not going to share them. also I'm not a car thief, just the guy folk call when the garages fail to unlock their cars or they cant get a call out. I can guarentee to get anybody into any car using methods that can be surprisingly quick and if not i always make sure i can get the correct glass before i start with a brick and duct tape (cover the glass before the brick). I've not worked in the body shop for a lot of years now but i keep up on these things as i still gets calls occaisonally.

But then again, I had a 1965 Chevy Bel Air wagon, and a friend of mine had a 1965 Chevy Impala 2-door. My door keys would start his car, and his would start mine. The ignition keys would work on the doors.

Automotive security has been a problem for a long time, and I wouldn't expect it to get much better - only different.

This is how the windshield wipers work on the spouse's Focus. I think the Fusion and the Escape work the same. Having two motors make it so you can manually move the wipers independently for cleaning, and they go through a parking process afterward that reminds me of Jeannie's arm cross / blink thing.

I believe they do this so they can use the same wiper system on both left and right hand drive. They aren't parallel motion, they are separate like a 1950s car. 

 

 

Wipers and Washers - System Operation and Component Description

System Operation

System Diagram

Network Message Chart

  BCM Network Input Messages

 

Broadcast Message	Originating Module	Message Purpose
Vehicle speed	ABS	The ABS module sends this message to the BCM . The BCM sends this data to the windshield wiper motor. The windshield wiper motor uses this data for the speed sensitive wiper feature.
Transmission in reverse	PCM	The reverse gear input is used to engage the reverse gear wipe function.

Windshield Wipers

The windshield wipers operate only when the ignition is in ACCESSORY or ON.

The SASM monitors the wiper/washer switch inputs and sends the wiper/washer switch data to the BCM through the LIN 1 (shared with the headlamp switch). Based on the input, the BCM sends the requested wiper speed data on the LIN 8 to the driver side windshield wiper motor. The driver side windshield wiper motor then coordinates the wiper operation with the passenger side windshield wiper motor (using an isolated communication circuit between the two of them) to prevent interference between the windshield wipers while they are operating.

The BCM also receives a second input through a fail-safe circuit from the SASM . This fail-safe circuit makes sure the windshield wipers function in the event a LIN 1 circuit communication failure occurs between the SASM and the BCM . If a failure occurs on the LIN 1, the wipers operate at LOW speed when the wiper/washer switch is in any position other than OFF.

If a communcation failure occurs on the LIN 8 circuit between the BCM and the windshield wiper motor, the windshield wipers operate for 5 minutes at high speed, 5 minutes at low speed, 5 minutes at an intermittent timing, and then turn off.

The wiper motor has a thermal protection strategy which disables the wiper motor when travel of the wiper arms is impeded by ice/snow and or excessive resistance as the result of operation on a dry windshield. The wipers may slow to a lower speed before being commanded off when a high friction situation/concern exists. It may be necessary to disconnect and then reconnect the battery after the repair to enable the wiper operation.

Windshield Washer

When the washer switch is pulled towards the driver, the SASM sends the washer request to the BCM over the LIN . The BCM activates the windshield wash relay (internal to the BCM ) and sends a message to the driver side windshield wiper motor. When the BCM activates the windshield wash relay, voltage is provided to the washer pump, directing washer fluid to the windshield. When the switch is released, the windshield wiper motor continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.

Intermittent Wipers

When the wiper switch is in the intermittent setting, the wiper motor activates at timed intervals. The lower the setting, the longer the interval between wipes.

Speed Dependent Wipers

When the wiper/washer switch is in any intermittent setting except the lowest setting, the speed dependent feature increases the frequency of wiping as the vehicle speed increases to compensate for the extra moisture that accumulates on the windshield.

The BCM receives the vehicle speed from the ABS module. The BCM then sends the vehicle speed data to the driver side windshield wiper motor through the LIN .

Wiper Activated Exterior Lamps

The BCM turns the exterior lamps on within 10 seconds of the windshield wipers being activated by the wiper/washer switch when the headlamp switch is in the AUTO position. Approximately 30 seconds after the windshield wipers turn off, the BCM turns the exterior lamps off.

Rear Window Wiper

When the wiper/washer switch is in the INT 1 or INT 2 (continuous wipe) position, the SASM sends the request to the BCM through the LIN . When the request is received, the BCM supplies ground to the rear window wiper motor relay, activating the motor. The position of the wiper/washer switch determines how many times per minute the BCM provides ground to activate the rear window wiper motor.

The rear window wiper motor is self-parking.

Rear Window Washer

When the wiper/washer switch is pushed away from the driver, the SASM sends the request to the BCM through the LIN . The BCM energizes the rear washer relay (internal to the BCM ) and activates the rear window wiper motor. When the BCM activates the rear window wash relay, voltage is provided to the washer pump, directing washer fluid to the rear window. When the switch is released, the rear window wiper motor continues to operate for 3 additional wipes and then turns off.

Reverse Gear Wipe

If the front wiper/washer switch is in any position other than off and the vehicle is in REVERSE, the rear window wiper activates.

Component Description

Wiper/Washer Switch

The wiper/washer switch is mounted directly to the SASM . The windshield wiper/washer inputs to the SASM are:

• Mist wipe
• Windshield wash
• Off
• AUTO 1/INT 1
• AUTO 2/INT 2
• AUTO 3/INT 3
• AUTO 4/INT 4
• AUTO 5/INT 5
• AUTO 6/INT 6
• Low
• High

The rear wiper/washer inputs to the SASM are:

• Off
• INT 1
• INT 2 (continuous wipe)
• Rear window wash

Front Wiper Motor

The windshield wiper motors contains a logic module, internal sensors (to monitor the wiper arm position) and a multi-speed motor. The logic module from the driver side windshield wiper motor continuously monitors the wiper/washer switch inputs from the BCM when the ignition is ON. Depending on the input, the wiper motor activates to achieve the desired request.

The driver side windshield wiper motor is the primary wiper motor and controls the operation of both windshield wipers.

There is no mechanical linkage between the motor and the wiper arm, the wiper arms are mounted directly to the wiper motors.

If a windshield wiper motor is replaced, the windshield wiper motors must be initialized.
Refer to: Windshield Wiper Motor Initialization (501-16 Wipers and Washers, General Procedures).

Washer Pump

The washer pump is controlled by the BCM . The front and rear washer system share the same washer reservoir and a bi-directional washer pump. The washer pump delivers washer fluid to the windshield when the BCM activates the windshield washer relay (internal to the BCM ), which provides voltage to the washer pump. Ground for the washer pump is provided through the rear washer relay (also internal to the BCM ). When activated, the washer pump delivers washer fluid to the windshield.

When the BCM energizes the rear washer relay, the rear washer relay provides voltage to the washer pump. Ground for the washer pump is provided through the windshield washer relay (internal to the BCM ). When activated, the pump delivers washer fluid to the rear window.

Rear Wiper Motor

The rear window wiper motor contains a single speed motor. When the BCM momentarily energizes the rear window wiper motor relay, the rear window wiper activates. A separate power circuit is used to continue the rear window wipe and park the rear window wiper.

And that same key would start Case skid steers and loaders too.

I'm thinking they do this for two reasons --
The logic required for things like wipers and lights is much cheaper as software
The amount of copper in the wiring is reduced. Copper has been especially expensive lately.

Why we do this? Because we can!  Let's network everything!  LAN, WAN, CAN, whatever it takes  Even your household light bulbs are on the Internet!  IoT baby! Hacker's paradise.

The key problem you mentioned goes back into the early 1950's and maybe even further. In the 60's, hanging out with friends in a parking lot it was somewhat of a joke to go around and open each other's trunks or unlock their cars using just the key to your own GM car. Seems at that time GM only used a very few key numbers for their products.

I think that wasn’t unusual, I’ve heard multiple stories about this with Ford products too, especially if they were near twins of each other. One with the 80’s or 90’s Taurus as well as 2000’s Explorers. My current boss used to own the latter before I worked for her and she had mentioned that she had gotten into what she though was her’s but the seats were all in the wrong position (ie-too far back) and couldn’t figure out why until she realized it wasn’t hers then found the right one after getting out of it. Keep in mind, it was almost identical to hers other than the license plate and seat/steering wheel settings.

My Dad's '67 Cougar and '69 Mustang are like that...I'm glad I found the keys for them when rescuing them from the barn last year, and didn't have to get them re-keyed like most of my late brother's cars.
