Low Traction Indicator Inoperative

Circuit Description
Four-way serial communication is sent back and forth between the EBCM, IPC, PCM, and the BCM. A message from the IPC is sent to the BCM within seven seconds after ABS initialization. A serial communication failure does not allow the proper warning indicator commands to be sent back to the IPC.

Diagnostic Aids
The following conditions may cause an intermittent malfunction:
^ A poor connection
^ Rubbed-through wire insulation
^ A broken wire inside the insulation
Use the Lamp Test function of the Scan Tool in order to turn the indicator ON and OFF while looking for an intermittent malfunction.
Thoroughly inspect any circuitry that may cause the intermittent complaint for the following conditions:
^ Backed out terminals
^ Improper mating
^ Broken locks
^ Improperly formed or damaged terminals
^ Poor terminal-to-wiring connections
^ Physical damage to the wiring harness
