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".
  1. CHECK WIPER MOTOR SIGNAL 

    With CONSULT-II

    Select "IPDM E/R" by CONSULT-II. With "DATA MONITOR", make sure that "WIP AUTO STOP" turns "ACT P" - "STOP P" linked with wiper operation.

    Without CONSULT-II

    GO TO 2.

    OK or NG 

    OK : Replace IPDM E/R.

    NG : GO TO 2.

  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 and front wiper motor harness connector E57 terminal 5.

      32 - 5 : Continuity should exist. 

    4. Check continuity between IPDM E/R harness connector E7 terminal 32 and ground.

      32 - Ground : Continuity should not exist.

  3. 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 E7 terminal 32 and ground while front wiper motor is stopped and while it is operating.
