1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Perform AT- 1 0 3 , "
OBD-II SELF-DIAGNOSTIC PROCEDURE (WITH GST)" . (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Select Mode 4 with GST (Generic Scan Tool). For details, refer to EC-135, "
Generic Scan Tool (GST)
Function" (for VQ35DE engine), EC-838, "Generic Scan Tool (GST) Function" (for VK45DE engine).

1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Perform AT- 1 0 3 , "
TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)" . (The engine warm-up step
can be skipped when performing the diagnosis only to erase the DTC.)
3. Perform “OBD-II SELF-DIAGNOSTIC PROCEDURE (No tools)”. Refer to EC-68, "
How to Erase DTC"
(for VQ35DE engine), EC-770, "How to Erase DTC" (for VK45DE engine).
Malfunction Indicator Lamp (MIL)NCS001K1
DESCRIPTION
The MIL is located on the combination meters.
1. The MIL will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.

If the MIL does not light up, refer to DI-39, "WARNING LAMPS" ,
or see EC-714, "
MIL AND DATA LINK CONNECTOR" (for
VQ35DE engine), EC-1438, "
MIL AND DATA LINK CONNEC-
TOR" (for VK45DE engine).
2. When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.
