Test F
PINPOINT TEST F: THE TRACTION CONTROL IS INOPERATIVETest F1-F3:
CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.
Normal Operation
Engine torque modulation is achieved by regulating fuel and spark to the cylinders. The traction control system operates using the ABS module to interact with the PCM to reduce engine torque if one or both rear wheels lose traction and begin to spin during acceleration.
Voltage is supplied by circuit 20-CF54 (PK/WH).
Possible Causes
^ Traction control switch C280.
^ Power circuit 20-CF54 (PK/WH).
^ Module.
