Front Wiper Does Not Return to Stop Position When Front Wiper Motor Operates at Low Speed


CAUTION:
- When auto stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this symptom.
- This status can be checked by "DATA MONITOR" of "IPDM E/R" on which "WIPER PROTECTION" item shows "BLOCK".
1.CHECK FRONT WIPER STOP SIGNAL
With CONSULT-III
1. Select "WIP AUTO STOP" of IPDM E/R data monitor item.
2. Check that "WIP AUTO STOP" turns "ACT P" - "STOP P" linked with wiper LO operation.
Without CONSULT-III
GO TO 2.
OK or NG
OK - Replace IPDM E/R. Refer to Service and Repair.
NG - GO TO 2.
2.CHECK IPDM E/R





Check voltage between IPDM E/R harness connector and ground while front wiper motor is stopped and while front wiper LO is operating.
