can anyone help?? both lights are always on in dash !!

 

You'll need to let us know the codes. I believe to get the codes you need to turn the key to the 'on' position but don't start. Then hold down the options button then press the fuel button 4 times. your codes will flash.

If that's not the right procedures someone please correct me.

 

Seems we're all having the same problem...
Here's my post about the same thing - yesterday

You mingt try erasing the codes first. I DIDN"T, now I thing I should have. If something is wrong, it will just throw the code again, no harm done. If the code comes back, then you know you have a problem.
Right guys? ? ? ?

See what codes are present

http://www.stengel.net/diccodes.htm.

Make sure you see what is after the code which will be an "H" or "HC"

For instance C1226HC indicates that there is a problem with reading the right front wheels speed sensor and it is a current problem. If it only had an "H" suffix it would of been a problem in the past but now just history. You can erase all codes as this is just a reporting mechanism and has no effect on the car operation.

 

i erased the codes and stills the 1235 "h", i have the "tomato" in stands and looking for wiring in the wheels (right rear). the thing is that stills the "h" code instead the "C"...do you know why?

 

Here is what the manual says:

Circuit Description
The speed sensor used on this vehicle is a single point magnetic pickup. This sensor produces an AC signal that the EBCM uses the frequency from to calculate the wheel speed.

Conditions for Setting the DTC
The DTC can be set any time the ignition is in the ON position, and the EBCM senses an open, a short to ground, or a short to battery.

Action Taken When the DTC Sets
ABS/TCS/Active Handling (if equipped with RPO JL4) are disabled.


Indicators that turn on:
ABS indicator
Car Icon (TCS indicator)
Messages displayed on the DTC:
Service ABS
Service Traction System
Service Active HNDLG (if equipped with Active Handling RPO JL4)
Conditions for Clearing the DTC


Condition for DTC is no longer present and scan tool clear DTC function is used.
Fifty ignition cycles have passed with no DTCs detected.
Diagnostic Aids


It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction.
An intermittent malfunction can be caused by poor connections, broken insulation, or a wire that is broken inside the insulation.
If an intermittent malfunction exists refer to Testing for Electrical Intermittents in Diagrams, Diagnostic Aids.
Test Description
The numbers below refer to step numbers on the diagnostic table.


Checks for an open in the WSS or WSS CKT.
Checks for a short to ground in the WSS or WSS CKT.
Checks for a short to voltage in the WSS CKT.
