Default ABS, Brake, ESP/BAS, Traction Control Dash Light stay on...

I got in my 2007 Aspen with 95k miles tonight and the above mentioned lights come on every time I start the vehicle. I checked the codes with a simple blue tooth code reader, nothing, no codes at all... just the ABS, Brake, ESP/BAS, Traction Control dash lights.

I've read about this a little after a forum search and internet search. Some mention speed sensors? or brake pad wear? Is there a known condition that is most likely causing this? Just trying to figure out where to focus my next round of troubleshooting...

Neighbor had the exact same issue on his Jeep for 2 years.. had someone finally scan it using an abs equipped scanner, and found it to be a wheel speed sensor... $40 part and 10 mins to change..

good luck.

Bought an ABS Scanner,
Code C2200 "ANTI-LOCK BRAKE MODULE INTERNAL"

Apparently the ABS control module is bad...
Is it a very difficult task to replace? Is it just a module and not the unit with all the brake lines running in and out of it?
I'll looking for videos on the subject...

removal steps:

1. Remove the left front tire and wheel assembly.
2. Disconnect the electrical connector from the ABM module.
3. Remove the module mounting screws (2).
4. Remove the module from the HCU (1) on ESP vehicles be careful not to damage the pressure sensor or not to touch the sensor terminals on the HCU side or the contact pads on the ABM side when removing the ABM.

installation steps:

1. Position the module on the HCU on ESP vehicles be careful not to damage the pressure sensor or not to touch the sensor terminals on the HCU side or the contact pads on the ABM side when installing the ABM.
2. Install the mounting screws (2) and tighten to 2.5 Nm (22 in. lbs).
3. Perform the ABS verification test with a scan tool.

note:

ELECTRONIC BRAKE CONTROL

The Antilock Brake Module (ABM) is a microprocessor which handles testing, monitoring and controlling the ABS brake system operation.

The ABM is mounted on the top of the hydraulic control unit (HCU). The ABM operates the ABS system and is separate from other vehicle electrical circuits. ABM voltage source is through CKT A111 (fused B+).

NOTE: If the ABM needs to be replaced, Perform the ABS verification using a scan tool.


note2:

ABS UNIT

SYSTEM SELF-TEST

When the ignition switch is turned-on the microprocessor is tested. If an error occurs during the test, a DTC will be set into the memory. However it is possible the DTC will not be stored in memory if the error has occurred in the module were the DTC's are stored.

The ABM contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in memory and are accessible with the scan tool.

ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected.

ABM INPUTS

The ABM continuously monitors the speed of the vehicle by monitoring signals generated by the wheel speed sensors. The ABM determines a wheel locking tendency when it recognizes the axle is decelerating too rapidly. The ABM monitors the following inputs to determine when a wheel locking tendency may exists:

Wheel Speed Sensors
Brake Lamp Switch
Brake Fluid Level Sensor (CAN C BUS)
G-Sensor (4X4)
ABM OUTPUTS

The ABM requests the following outputs for antilock braking and brake warning information from the CCN via CAN C Bus:

ABS Warning Lamp
Brake Warning Lamp


hope this helps

Default Same lights, different code...

I see that this is an older thread. However, I'm having a similar issue. My wife was coming home in her 2007 Chrysler Aspen and noticed the car would no longer accelerate beyond about 30 mph. All the lights mentioned in the thread came on. I took a look at it the next day, it crank up with no problem, except the RPM was a bit higher and then it settled after a minute or so. The lights remained on. I drove it and after a few miles experienced the same deal, won't go passed 30 mph although the RPM continues to rise (while giving it gas). I found this thread, got a scanner with ABS, but only gives code U0401 which is not specific enough. An ABS module cost a bit, so want to know the issue before just changing parts. Any advice is appreciated.

I had a problem with the ESP/BAS and Traction control lights staying on. Found out that the previous owner had the airbags replaced under a recall and while being done the clockspring in the steering wheel was damaged causing these lights to come on. From what I know there is a steering angle (?) adjustment on the clock spring and if that is damaged then it causes this problem. Unfortunately, the part from Chrysler is $900 + labor. I took it back to the dealer that did the recall and they agreed with the damage to the clockspring and are replacing it free of charge under warranty. If yours has had the recall done for the airbags this may be your problem, it was for me. The recall bulletin has a section warning the technicians not to damage the clockspring while performing the recall, so I'm guessing it happens more than Chrysler would like. Hope this helps.

Took it to a shop and the throttle position sensor and a hose with vacuum leak was replaced. That cleared all the lights and Aspen driving fine. Only cost me $292.

HMMM, I just had the airbags replaced and now I'm getting the lights as mentioned above....


Guess I'll have to try to get the dealer to fix it for me!
