DESCRIPTION
Code 3 is generated by the anti-lock electronic control module's detection of an open circuit in line 664 (Y/LG) or 274 (BK/W). The code may also be generated by a failed dump solenoid (open coil) internal to the RABS valve or a failed internal anti-lock electronic control module circuit.
POSSIBLE CONTRIBUTING BASE BRAKE COMPONENT/VEHICLE WIRING CONCERNS
- Terminal backout in the anti-lock electronic control module harness connector at Pins 8 or 14
- Terminal backout in the RABS valve harness connector at Pin 4
- Bulkhead connector (between engine compartment and instrument panel) terminal backout or loose connection
- Anti-lock electronic control module or RABS valve connectors not fully mated with component
- Intermittent open circuit in line 664 (Y/LG)
NOTE: Use Rotunda(r) 73 Digital Multimeter 105-00051 or equivalent for electrical tests.
