After Front Wipers Operate For 10 Seconds, They Stop For 20 Seconds, And After Repeating The Operations Five Times, They Become Inoperative

NOTE:

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".

Check Wiper Motor Signal
1. With CONSULT-II
  Select "IPDM E/R" by CONSULT-II. With "DATA MONITOR", confirm that "WIP AUTO STOP" turns "ACT P" - "STOP P" linked with wiper operation.
  1. When front wiper stopped : WIP AUTO STOP STOP P
  2. When front wiper operated : WIP AUTO STOP ACT P
2. Without CONSULT-II
  GO TO 2 .
OK or NG
1. OK: Replace IPDM E/R.
2. NG: GO TO 2 .

Check Wiper Auto Stop Circuit
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 E7 terminal 32 (L) and front wiper motor harness connector E57 terminal 5 (L).
  1. 32 (L) - 5 (L) : Continuity should exist.
4. Check continuity between IPDM E/R harness connector E7 terminal 32 (L) and ground.
  1. 32 (L) - Ground : Continuity should not exist.
OK or NG
1. OK: GO TO 3 .
2. NG: Repair harness or connector.

Check Front Motor
1. Connect IPDM E/R connector and front wiper connector.
2. Turn ignition switch ON.
3. Check voltage between IPDM E/R harness connector E7 terminal 32 (L) and ground while front wiper motor is stopped and while it is operating.

OK or NG
1. OK: Replace IPDM E/R.
2. NG: GO TO 4 .
Check IPDM E/R (2)
1. Turn ignition switch OFF.
2. Disconnect front wiper motor connector.
3. Turn ignition switch ON.
4. Check voltage between front wiper motor connector E57 terminal 5 (L) and ground.
  1. 5 (L) - Ground : Battery Voltage should exist.
OK or NG
1. OK: Replace front wiper motor.
2. NG: Replace IPDM E/R.
