4. Start engine and let it idle for 1 second.
5. If DTC is detected, go to "AT-135, "Diagnostic Procedure".
WITH GST
Follow the procedure "WITH CONSULT-II".
Diagnostic Procedure
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to AT-94, "SELF-DIAGNOSTIC RESULT MODE", CONSULT Inspection Procedure and AT-104, "Diagnostic Procedure without CONSULT-II". Transmission Control Systems
Is a malfunction in the CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to "DTC U1000 CAN COMMUNICATION LINE".
NO >> GO TO 2.
2. CHECK DTC WITH TCM
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT-II.
3. Depress accelerator pedal and read out the value of "ACCELE POSI" and "THROTTLE POSI".
4. Select "SELF-DIAG RESULTS" mode for "A/T" with CONSULT-II. Refer to "SELF-DIAGNOSTIC RESULT MODE"
With GST
Follow the procedure "With CONSULT-II".
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. CHECK DTC WITH ECM
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select "SELF-DIAG RESULTS" mode for "ENGINE" with CONSULT-II. Refer to "CONSULT-II Function (ENGINE)" (for VQ35DE) or "CONSULT-II Function (ENGINE)" (for VK45DE).
With GST

4. CHECK DTC
Perform "DTC Confirmation Procedure".
^ Refer to AT-134, "DTC Confirmation Procedure".
OK or NG
OK >> INSPECTION END
NG >> GO TO 5.
5. CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
