IPDM E/R Power/Ground Circuit InspectionEKS00JLQ
1. FUSE AND FUSIBLE LINK INSPECTION
Check that the following fusible links or IPDM E/R fuses are not blown.
OK or NG
OK >> GO TO 2.
NG >> Replace fuse or fusible link.
2. POWER CIRCUIT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R harness connector E42.
3. Check voltage between IPDM E/R harness connector E42 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 E46 and E48.
2. Check continuity between IPDM E/R harness connector E46
(A) terminal 39, E48 (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)EKS00JLR
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) carry out CAN communication.
1. SELF-DIAGNOSIS RESULT CHECK
1. Connect CONSULT-II and select "IPDM E/R" on the "SELECT SYSTEM" screen.
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.

Removal and Installation of IPDM E/REKS00JWA
: Vehicle front
REMOVAL
1. Lift up the IPDM E/R while pushing and opening pawls (A) or
(B), and remove the IPDM E/R while pushing and opening the
other side pawls.
2. Disconnect harness connector.
