CHECK IPDM E/R
With CONSULT-II
1.
Connect IPDM E/R connector and front wiper motor connector.
2.
Install front wiper reverse relay.
3.
Select “IPDM E/R” on CONSULT-II. Select “ACTIVE TEST” on “SELECT DIAG MODE” screen.
4.
Select “FRONT WIPER” on “SELECT TEST ITEM” screen.
5.
Touch “LO” or “HI” screen.
6.
Check voltage between IPDM E/R harness connector and
ground while front wiper (HI, LO) is operating.
Without CONSULT-II
1.
Connect IPDM E/R connector and front wiper motor connector.
2.
Install front wiper reverse relay.
3.
Start up auto active test. Refer to
4.
Check voltage between IPDM E/R harness connector and ground while front wiper (HI, LO) is operating.
OK or NG
OK
>> Replace front wiper motor. Refer to
WW-44, "Disassembly and Assembly of Front Wiper Drive
NG
>> Replace IPDM E/R. Refer to
PG-31, "Removal and Installation of IPDM E/R"
.
Front Wiper Does Not Return to Stop Position (After Front Wiper Operate for 10
Seconds, They Stop for 20 Seconds, and After Repeating the Operations Five
Times, They Become Inoperative)
NKS003WO
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”.
