Front Wiper Does Not Return to Stop Position (After Front Wipers Operate for
10 Seconds, They Stop for 20 Seconds, and after repeating the operations five
times, they become inoperative)
BKS001TS
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 front wiper output. That
causes this symptom.
This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIP PROT” item shows
“BLOCK”.
1. CHECK BCM DATA MONITOR
With CONSULT-II
1. Select “BCM” on CONSULT-II, and select “WIPER” on “SELECT TEST ITEM” screen.
2. Select “DATA MONITOR” on “SELECT DIAG MODE” screen.
Make sure that “FR WIPER STOP” turns ON-OFF according to
front wiper operation.

NG >> GO TO 2.
2. CHECK CIRCUIT BETWEEN IPDM E/R AND FRONT WIPER MOTOR
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and front wiper motor connector.
3. Check continuity between IPDM E/R harness connector (A) and
front wiper motor harness connector (B).
4. Check continuity between IPDM E/R harness connector (A) and
ground.
