P0615

DTC P0615 START SIGNAL CIRCUIT

Description
- TCM controls starter relay in IPDM E/R.
- TCM switches starter relay ON at "P" or "N" position and allows to crank engine.
- Then it prohibits cranking other than at "P" or "N" position.

CONSULT-III Reference Value in Data Monitor Mode:

On Board Diagnosis Logic
- This is not an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0615 STARTER RELAY/CIRC" with CONSULT-III is detected when starter relay switched ON other than at "P" or "N" position. (or when switched OFF at "P" or "N" position).

Possible Cause
- Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
- Starter relay

DTC Confirmation Procedure

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 confirm 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 "Diagnostic Procedure" below.

CVT-STSIG-01:

TCM TERMINALS AND REFERENCE VALUES
Refer to CVT-45, "TCM Terminal and Reference Value". Continuously Variable Transmission

Diagnostic Procedure

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.
- Open or short-circuit in the harness between TCM and the starter relay.
- Ground circuit for the starter relay.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.

3. CHECK DTC
Perform "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". Continuously Variable Transmission
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.
