Warning lights

[citiboy]

Yes, my cruise control normally works, but i never tried to put it ON when the ABS/TCS light was ON.

Before i erased the code, i checked the ABS/TCS snapshot from the Tech 2 and found that the RR wheel sensor speed is 0km while the 3 sensors at 55km.

I first check the wiring from the RR wheel sensor to the EBCM and found no problem as per GM service manual flowchart.

I just changed the RR wheel sensor, road test with the Tech 2 and all wheel sensors reading are the same.

It's all good for now.

The following are the main components of the Cruise Control System:
 The accelerator pedal
 The stop lamp switch
 The body control module (BCM)
 The cruise control switches
 The engine control module (ECM)
 The throttle actuator control (TAC) motor
 The vehicle speed sensor (VSS)

Cruise Control Inhibited
The engine control module (ECM) inhibits the cruise control operation when any of the following conditions exist:
 The ECM has not detected a brake pedal activation from the body control module (BCM).
 A Cruise Control System DTC has been set.
 The vehicle speed is less than 40.2 km/h (25 mph).
 The vehicle speed is too high.
 The vehicle is in PARK, REVERSE, NEUTRAL, or 1st gear.
 The engine RPM is too low.
 The engine RPM is too high.
 The system voltage is not between 9-16 volts.
 The Antilock Brake System (ABS)/Traction Control System (TCS) is active for more than 2 seconds.
