TRACTION CONTROL SYSTEM (TCS) TROUBLESHOOTINGTroubleshooting notes
Some of the electrical components of the TCS are shared with the ABS and engine control. Malfunction of the TCS electrical components is judged by the on-board diagnosis function within the engine control module and/or ABS/TCS control module. Malfunctions are indicated by the warning light in the instrument panel. The technician can locate the malfunctions by using the SST (NGS set).

^ When TGS OFF is selected by the TCS OFF switch.
The warning light will be oft and the TCS will be ready for operation when the TCS OFF switch is pressed again.
^ When (while the vehicle is jacked up or stuck) the front wheels only are spun for 60 seconds or more.
The warning light will not illuminate a second time when the ignition is switched OFF then back ON, and there will also be no diagnostic trouble code entry made to the control module memory.
^ When there is insufficient battery voltage.
The warning light will be oft and the TCS will be ready for operation when the battery voltage rises. There will also be no diagnostic trouble code entry made to the control module.
^ When the engine coolant temperature is extremely low.
The warning light will be off and the TCS will be ready for operation when the engine coolant temperature rises. There will also be no diagnostic trouble code entry made to the control module memory.
