Diagnostic Procedure without CONSULT-IINCS001KI
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-135, "Generic Scan Tool (GST) Function" (for VQ35DE engine), EC-838, "Generic Scan Tool
(GST) Function" (for VK45DE engine).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-70, "Malfunction Indicator Lamp (MIL)" (for VQ35DE engine), EC-772, "Malfunction Indicator
Lamp (MIL)" (for VK45DE engine).
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
As a method for locating the suspect circuit, when the self-diagnostics start signal is input, the memory for the
malfunction location is output and the A/T CHECK indicator lamp flashes to display the corresponding DTC.
Operation Procedure
1. CHECK A/T CHECK INDICATOR LAMP
1. Start the engine with selector lever in “P” position. Warm engine to normal operating temperature.
2. Turn ignition switch ON and OFF at least twice, then leave it in the OFF position.
3. Wait 10 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does A/T CHECK indicator lamp come on for about 2 seconds?
YES >> GO TO 2.
NO >> GO TO AT- 1 9 0 , "
A/T CHECK Indicator Lamp Does Not Come On" .
2. JUDGEMENT PROCEDURE
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Release accelerator pedal. (Set the closed throttle position signal ON.)
5. Depress brake pedal. (Stop lamp switch signal ON.)
6. Turn ignition switch ON.
7. Wait 3 seconds.
8. Move the selector lever to the manual shift gate side. (Manual mode signal ON.)
9. Release brake pedal. (Stop lamp switch signal OFF.)
10. Move the selector lever to “D” position. (Manual mode signal OFF.)
11. Depress brake pedal. (Stop lamp switch signal ON.)
12. Release brake pedal. (Stop lamp switch signal OFF.)
13. Depress accelerator pedal fully and release it.
>> GO TO 3.
3. CHECK SELF-DIAGNOSIS CODE
Check A/T CHECK indicator lamp.
Refer to AT- 1 0 4 , "
Judgement Self-diagnosis Code" .
If the system does not go into self-diagnostics. Refer to AT- 11 3 , "

DTC P0615 START SIGNAL CIRCUITPFP:25230
DescriptionNCS001KP
TCM prohibits cranking other than at “P” or “N” position.
CONSULT-II Reference ValueNCS001KQ
On Board Diagnosis LogicNCS001KR

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" .

Revision: 2007 April2007 M35/M45
TCM terminals and data are reference value. Measured between each terminal and ground.
Diagnostic ProcedureNCS001KV
1. CHECK STARTER RELAY
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.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between the IPDM E/R connector and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2. CHECK HARNESS BETWEEN A/T ASSEMBLY HARNESS CONNECTOR AND IPDM E/R CONNEC-
TOR
1. Turn ignition switch OFF.
2. Disconnect A/T assembly harness connector and IPDM E/R connector.
3. Check continuity between A/T assembly harness connector and
IPDM E/R connector.
4. If OK, check harness for short to ground and short to power.
5. Reinstall any part removed.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
