P0615

DTC P0615 START SIGNAL CIRCUIT

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





CONSULT-II Reference Value

On Board Diagnosis Logic
^ This is not an OBD-II self-diagnostic item.
^ Diagnostic trouble code "STARTER RELAY/CIRC" with CONSULT-II or 14th judgment flicker without CONSULT-II is detected when detects as irregular when park/neutral (PNP) relay (starter relay) is switched "ON" other than at "P" or "N" position. (Or when switched "OFF" at "P" or "N" position).

Possible Cause
^ Harness or connectors
[The Park/Neutral Position (PNP) relay (starter relay) and TCM circuit is open or shorted.]
^ Park/Neutral Position (PNP) relay (starter relay)

DTC Confirmation Procedure

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, perform the following procedure to confirm the malfunction is eliminated.

WITH CONSULT-II
1. Turn ignition switch "ON". (Do not start engine.)





2. Select "DATA MONITOR" mode for "A/T" with CONSULT-II.
3. Start engine.
4. Drive vehicle for at least 2 consecutive seconds.
5. If DTC is detected, go to "Diagnostic Procedure".

Diagnostic Procedure
1. CHECK STARTER RELAY
With CONSULT-II
1. Turn ignition switch "ON". (Do not start engine.)





2. Select "SELECTION FROM MENU" in "DATA MONITOR" mode for "A/T" with CONSULT-II and check monitor "STARTER RELAY" ON/OFF.

Without CONSULT-II
1. Turn ignition switch "ON". (Do not start engine.)








2. Check voltage between the IPDM E/R connector and ground. Refer to "Wiring Diagram-AT-".

OK or NG
OK >> GO TO 3.
NG >> GO TO 2.

2. DETECT MALFUNCTIONING ITEM
Check the following items:
^ Starter relay, Starting System
^ Open or short-circuits in the harness between TCM and the IPDM E/R.

OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.

3. CHECK TCM
Perform TCM input/output signal inspection.

OK or NG
OK >> GO TO 5.
NG >> GO TO 4.

4. DETECT MALFUNCTIONING ITEM
Check the following items:
^ Power supply and ground circuit for TCM. Pinout Values and Diagnostic Parameters
^ The A/T assembly harness connector pin terminals for damage or loose connection with harness connector.

OK or NG
OK >> Replace the transmission assembly.
NG >> Repair or replace damaged parts.

5. CHECK DTC
Perform DTC Confirmation Procedure.

OK or NG
OK >> INSPECTION END
NG >> GO TO 3.
