This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “P0615 STARTER RELAY/CIRC” with CONSULT-II or 14th judgement flicker
without CONSULT-II is detected when starter relay is switched ON other than at “P” or “N” position. (Or
when switched OFF at “P” or “N” position).
Possible CauseNCS001KS

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

Starter relay circuit
DTC Confirmation ProcedureNCS001KT
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.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “A/T” with CONSULT-II and check monitor “STARTER
RELAY” ON/OFF.
3. Start engine.
4. Drive vehicle for at least 2 consecutive seconds.
5. If DTC is detected, go to AT- 11 0 , "
Diagnostic Procedure" .

minal and TCM connector terminal.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG >> Replace open circuit or short to ground and short to power in harness or connectors.
4. DETECT MALFUNCTIONING ITEM
Check the following.

Starter relay, Refer to SC-8, "STARTING SYSTEM" .

IPDM E/R, Refer to PG-18, "IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE
ROOM)" .
OK or NG
OK >> Replace the control valve with TCM. Refer to AT- 2 3 6 , "Control Valve With TCM and A/T Fluid
Temperature Sensor 2" .

DTC P1815 MANUAL MODE SWITCH
Revision: 2007 April2007 M35/M45
TCM terminals and data are reference value. Measured between each terminal and ground.
Diagnostic ProcedureNCS001OZ
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" .
Is a malfunction in the CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to AT- 1 0 5 , "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK MANUAL MODE SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out ON/OFF switching action of “MANU MODE SW”,
“NON M-MODE SW”, “UP SW LEVER”, “DOWN SW LEVER”.
Without CONSULT-II
Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the
position mutually coincide when the selector lever is shifted to the “+ (up)” or “- (down)” side (1st ⇔ 5th gear).
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
