DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If “DTC CONFIRMATION PROCEDURE” is previously c onducted, always turn ignition switch OFF and wait at
least 10 seconds before performing the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
With CONSULT-III
1. Shift the selector lever to “P” and “N” positions.
2. Turn ignition switch ON and wait 2 seconds or more.
3. Perform “Self Diagnostic Results” in “TRANSMISSION”.
Is
“P0615” detected?
YES >> Go to TM-104, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000006226803
1.CHECK STARTER RELAY SIGNAL
1. Turn ignition switch ON.
2. Check voltage between IPDM E/R connector terminal and ground.
Is the inspection result normal?
YES >> Check starter relay circuit. Refer to STR-7, "Wiring Diagram".
NO >> GO TO 2.
2. CHECK HARNESS BETWEEN A/T ASSEMBLY AND IPDM E/R (PART 1)
1. Turn ignition switch OFF.
2. Disconnect A/T assembly c onnector and IPDM E/R connector.
3. Check the continuity between A/T assembly vehi cle side harness connector terminal and IPDM E/R vehi-
cle side harness connector terminal.
