After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five Times, They Become Inoperative

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".

CHECK WIPER MOTOR SIGNAL
With CONSULT-III
1. Select "WIP AUTO STOP" of BCM data monitor item.
2. Check that "WIP AUTO STOP" turns "ACT P" - "STOP P" linked with wiper operation.
Without CONSULT-III

GO TO 2.

OK or NG

OK: Replace IPDM E/R.

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 and front wiper motor harness connector.
  32 - 5 : Continuity should exist.
4. Check continuity between IPDM E/R harness connector and ground.
  32 - Ground : Continuity should not exist.

OK: GO TO 3.

NG: Repair harness or connector.
CHECK FRONT WIPER 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 and ground while front wiper motor is stopped and while it is operating.
