2.
POWER CIRCUIT INSPECTION
1.
Turn ignition switch off.
2.
Disconnect IPDM E/R harness connector E118.
3.
Check voltage between IPDM E/R harness connector E118 terminals 1, 2 and ground.
OK or NG
OK
>> GO TO 3.
NG
>> Repair or replace IPDM E/R power circuit harness.
3.
GROUND CIRCUIT INSPECTION
1.
Disconnect IPDM E/R harness connectors E122 and E124.
2.
Check continuity between IPDM E/R harness connectors E122
(A) terminal 38, E124 (B) terminal 59 and ground.
OK or NG
OK
>> Inspection End.
NG
>> Repair or replace IPDM E/R ground circuit harness.

Inspection with CONSULT-II (Self-Diagnosis)
EKS00G8M
CAUTION:
If a CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on which control unit(s) carries out CAN communication.
1.
SELF-DIAGNOSIS RESULT CHECK
1.
Connect CONSULT-II and select "IPDM E/R" on the "SELECT SYSTEM".
2.
Select "SELF-DIAG RESULTS" on the "SELECT DIAG MODE" screen.
3.
Check display content in self-diagnosis results.
NOTE:
The Details for Display for the Period are as follows:
●
CRNT: Error currently detected by IPDM E/R.
●
PAST: Error detected in the past and stored in IPDM E/R memory.
Contents displayed
NO DTC DETECTED. FURTHER TESTING MAY BE REQUIRED.>>Inspection End.
