Diagnostic Procedure without CONSULT-IIACS008CZ
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)
Refer to EC-144, "Generic Scan Tool (GST) Function" (for VQ35DE) or EC-835, "Generic Scan Tool (GST)
Function" (for VK45DE).
OBD-II SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Refer to EC-69, "Malfunction Indicator Lamp (MIL)" (for VQ35DE) or EC-760, "Malfunction Indicator Lamp
(MIL)" (for VK45DE).
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)
Description
In the unlikely event of a malfunction in the electrical system, when the ignition switch is switched “ON”, the A/
T CHECK indicator lamp lights up for 2 seconds, then flashes for 8 seconds. If there is no malfunction, when
the ignition switch is turned “ON”, the indicator lamp lights up for 2 seconds. As a method for locating the sus-
pect 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.
Diagnostic 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 3
.
2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch “OFF”.
2. Push 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”. (Do not start engine.)
7. Wait 3 seconds.
>> GO TO 3.
3. JUDGEMENT PROCEDURE STEP 2
1. Move the selector lever to the manual shift gate side. (Manual mode switch “ON”.)
2. Release brake pedal. (Stop lamp switch signal “OFF”.)
3. Move the selector lever to “D” position. (Manual mode switch “OFF”.)
4. Depress brake pedal. (Stop lamp switch signal “ON”.)
5. Release brake pedal. (Stop lamp switch signal “OFF”.)
6. Depress accelerator pedal fully and release it.
>> GO TO 4.

DTC P0615 START SIGNAL CIRCUITPFP:25230
DescriptionACS003LO

TCM prohibits cranking other than at “P” or “N” position.
CONSULT-II Reference ValueACS003K2
On Board Diagnosis LogicACS002MH

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 CauseACS003LP

Harness or connectors
[Starter relay and TCM circuit is open or shorted.]

Starter relay circuit
DTC Confirmation ProcedureACS002MJ
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 “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- 111 , "
Diagnostic Procedure" .
