Circuit Description
WARNING: This page is about a different car, the 2002 Infiniti QX4, 2001 Nissan Pathfinder, and 2001 Infiniti QX4. However, it is still accessible from the selected car via links, so may be relevant.
This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis. This DTC will not be detected while the O/D OFF indicator light is indicating another self-diagnosis malfunction. This DTC is detected when the transmission does not shift into 4th gear, or the TCC does not lock-up as instructed by the TCM. This is not caused by electrical malfunction (circuits open or shorted), but by mechanical malfunction (such as control valve sticking, improper solenoid valve operation, malfunctioning oil pump or torque converter clutch, etc.).
