DIAGNOSTIC PROCEDURE - WIPER ON/OFF RELAY OUTPUT SHORTED LOW
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition on. With the DRBIII®, clear all BCM DTC's. Actuate the Wipers. With the DRBIII®, read the DTC information. Does the DRBIII® read: Wiper On/Off Relay Output Shorted Low? Yes --> Go To 2 No --> The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires. Perform BODY VERIFICATION TEST - VER 1 . |

Does the Wiper Relay show CLOSED? Yes --> Repair the HI/LO Wiper Relay Control Circuit for an open condition. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 3 |
All |
| 3 | Turn the ignition off. Remove the HI/LO Wiper Relay. Disconnect the BCM from the junction block. Measure the resistance of the HI/LO Wiper Relay Output Circuit. Is the resistance below 5.0 ohms? Yes --> Repair the HI/LO Wiper Relay Output Circuit for a short to ground condition. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 4 |
All |
| 4 | Turn the ignition off. Install a known good relay in place of the HI/LO Wiper Relay. Turn the wipers on. Do the Wipers operate normally? Yes --> Replace the Wiper HI/LO Relay.
