Pump/Motor Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see wiring diagram.
- Remove pump/motor fuse No. 48 (40-amp), located in Power Distribution Center (PDC). Turn ignition off. Remove pump/motor relay. Inspect, clean and repair connector as necessary. Using scan tool in ohmmeter mode, check resistance of Red/Dark Green wire at pump/motor relay connector. If resistance is less than 5 ohms, repair short to ground in Red/Dark Green wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
- Disconnect modulator assembly 10-pin connector. Using scan tool, check resistance of Brown/White wire at pump/motor relay connector. If resistance is less than 5 ohms, repair short to ground in Brown/White wire. Perform TEST VER-1A. If resistance is more than 5 ohms, go to next step.
- Replace ABS PUMP/MOTOR fuse, fuse No. 48 or Gray fusible link. Reconnect all disconnected connectors. Using scan tool, actuate pump/motor. Check ABS PUMP/MOTOR fuse, fuse No. 48 or Gray fusible link. If fuse or fusible link is open, replace modulator assembly. Perform TEST VER-1A. If fuse or fusible link is okay, pump/motor circuit is operating properly at this time. Perform TEST VER-1A.
