### Traction Active Telltale Circuit Fault

The traction active telltale lamp should turn On for a bulb check when the ignition is turned to RUN. Three seconds later, if the ABS control module doesn't detect a fault, the telltale lamp should turn Off. The ABS control module turns the traction active telltale lamp On by providing a ground path for the telltale lamp circuit.

### Code Parameters

Code 13 sets if:

The traction active telltale lamp circuit is open, grounded, or shorted to battery.

When code 13 sets:

The service telltale lamp is turned On.

ABS is enabled.

### Diagnostic Aids

Important: Grounding the circuit from the cluster to the ABS control module will cause the telltale lamp to turn On. Opening the circuit will turn the telltale Off.

When attempting to diagnose an intermittent problem, use the Scan tool to review supplemental diagnostic information. The supplemental data can be used to duplicate a problem.

Select Malf History from scan tool ABS menu.

Check tightness of the female terminal grip with a spare male terminal.
