DTC Confirmation ProcedureINFOID:0000000001703480
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Start engine.
4. Drive vehicle for at least 2 consecutive seconds.
5. If DTC is detected, go to CVT-62, "
Diagnosis Procedure" .

DTC P0615 START SIGNAL CIRCUIT
Diagnosis Procedure
INFOID:0000000001703482
1.CHECK STARTER RELAY SIGNAL
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “STRTR RLY OUT”, “STRTR RLY MON”(PNP relay) ON/OFF.
Without CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between the TCM connector terminal and
ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2.DETECT MALFUNCTIONING ITEM
Check the following:
• Starter relay. Refer to PG-69
.
• Open or short-circuit in the harness between TCM and the starter relay. Refer to CVT-61, "
Wiring Diagram -
CVT - STSIG" .
• Ground circuit for the starter relay. Refer to SC-10, "
Wiring Diagram - START -" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3.CHECK DTC
Perform CVT-60, "
DTC Confirmation Procedure" .
OK or NG
OK >>INSPECTION END
NG >> GO TO 4.
4.CHECK TCM
1. Check TCM input/output signals. Refer to CVT-45, "
TCM Terminal and Reference Value" .
2. If NG, re-check TCM pin terminals for damage or loose connection with harness connector.
OK or NG
OK >>INSPECTION END
NG >> Repair or replace damaged parts.
