4E-42 ABS:
Traction Control Indicator Always On
Circuit Description
The TRAC OFF indicator is controlled by the instrument cluster via class 2 serial data messages from the electronic
brake control module (EBCM). When the body control module (BCM) sees the traction control switch input grounded
through the momentary traction control switch, it sends a class 2 message to the EBCM that tells the EBCM that the
traction control switch has been pressed. The EBCM then disables traction control and sends a message to the
instrument cluster to turn the TRAC OFF indicator ON. Each time the ignition is cycled from OFF to ON, the traction
control system (TCS) is enabled.
The following conditions will cause the TRAC OFF indicator to illuminate:
• The EBCM has disabled the TCS due to a DTC.
• The driver manually disabling the TCS via the traction control switch.
• The instrument cluster bulb check. When the ignition switch is turned to ON, the TRAC OFF indicator will turn on for
approximately 3 seconds and then turn OFF.
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.
• Thoroughly inspect any circuitry that may be causing the 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
• The following conditions may cause an intermittent malfunction:
– A poor connection
– Rubbed-through wire insulation
– A broken wire inside the insulation
• If an intermittent malfunction exists refer "Inducing Intermittent Fault Conditions: " in Wiring Systems for further
diagnosis.
