gram - IGNITION POWER SUPPLY -"

.

• Open circuit or short circuit in harness between IPDM E/R harness connector terminal 61 and TCM harness

connector terminal 47, and 48.

• 10A fuse (No.46, located in the IPDM E/R). Refer to 

PG-85, "IPDM E/R Terminal Arrangement"

.

• IPDM E/R
Is the check result normal?

YES

>> Check intermittent incident. Refer to 

GI-49, "Intermittent Incident"

.

NO

>> Repair or replace malfunctioning parts.

YES

>> INSPECTION END

NO

>> Go to 

TM-169, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000009177624

1.

CHECK TCM INPUT/OUTPUT SIGNAL 

With CONSULT

1. Start the engine.

2. Select “Data Monitor” in “TRANSMISSION”.

3. Select “RANGE”. 

4. Shift selector lever.

5. Check that selector lever position, “RANGE” on CONSULT screen, and shift position indicator display on

combination meter are identical.

 Is the check result normal?

YES

>> INSPECTION END

NO-1 (“RANGE” is changed but is not displayed on shift position indicator.>>Check “Self Diagnostic Result”

in “TRANSMISSION”.

NO-2 (“RANGE” and shift position indicator are different.)>>Check “Self Diagnostic Result” in “TRANSMIS-

SION”.

NO-3 (Specific “RANGE” is not displayed on shift position indicator.)>>Check “Self Diagnostic Result” in

“METER/M&A”.
