Circuit/System Testing
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the rear window wiper motor.
- Ignition ON, test for B+ between the signal circuit terminal E and ground.
- If less the specified value, test the signal circuit for a short to ground or an open/high resistance.
- Rear washer switch closed, test for less than 10 ohms of resistance between the signal circuit terminal E and ground.
- If greater than the specified range, test the signal circuit for an open/high resistance. If the circuit tests normal, test or replace the rear wiper/washer switch.
- Ignition OFF, connect the harness connector at the rear window wiper motor. Disconnect the harness connector at the windshield washer pump.
- Test for less than 20 ohms of resistance between the ground circuit terminal 2 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Install a test lamp between the control circuit terminal 1 and the ground circuit terminal 2.
- Ignition ON, command the rear washer ON using the rear wiper/washer switch. The test lamp should illuminate.
- If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the underhood fuse block.
- If all circuits test normal, test or replace the windshield washer pump.
