2001 CHRYSLER VOYAGER brake

Symptom:
*TRAC ON INDICATOR NEVER/ALWAYS ON
POSSIBLE CAUSES
CAB -- INTERNAL FAULT
CHECK TRACTION CONTROL SYSTEM
CLUSTER FAILS SELF TEST
CAB - NO TRAC MESSAGE
TEST ACTION APPLICABILITY
1NOTE: The DRBIIItmust be able to communicate with the CAB prior to
performing this test.
NOTE: Note: If any CAB DTC's are present, they must be repaired prior to
performing this test.
Perform the KEY-ON bulb test.
Did the TRAC Indicator illuminate and then go out?All
Ye s®Go To 2
No®Go To 3
2 Make sure the Traction Control system has not been deactivated with the TRAC OFF
switch.
NOTE: The purpose of this test is to determine if the Traction Control
system is operating.
With the DRBIIItin Inputs/Outputs, read the ABS Pump Motor voltage state.
Accelerate sufficient to cause drive wheel slip.
Does the TRAC Indicator illuminate and the DRBIIItdisplay approximately 9 volts?All
Ye s®The traction control system is functioning normally.
Perform ABS VERIFICATION TEST - VER 1.
No®Replace the Controller Antilock Brake in accordance with the
Service Information.
Perform ABS VERIFICATION TEST - VER 1.
3NOTE: The purpose of this test is to perform the Instrument Cluster self
test.
Depress and hold the Odometer Reset Button.
Turn the Key from OFF to ON and then back to OFF.
Release the Odometer Reset Button.
Do the Instrument Cluster Indicators and Gauges activate and deactivate?All
Ye s®Replace the Controller Antilock Brake in accordance with the
Service Information.
Perform ABS VERIFICATION TEST - VER 1.
No®Replace the Instrument Cluster in accordance with the Service
Information.
Perform ABS VERIFICATION TEST - VER 1.
