Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) for DTC P254F.

Circuit/System Testing

Note: An intermittent or momentary, less than 1 s, loss of system voltage during throttle tip-in may set DTC P060D.

1. Ignition ON, clear the DTC information with a scan tool. Observe the scan tool DTC information. Verify that DTCs P0602 or P2610 do not

fail this ignition cycle.

瀚慖f DTC P0602 failed this ignition, reprogram the ECM. Refer to Control Module References (See: Testing and Inspection/Programming

and Relearning). If DTC P0602 resets, replace the ECM.

瀚慖f DTC P2610 failed this ignition, test the ECM ignition, battery positive voltage, and ground circuits for an open/high resistance or a

short to ground. If the circuits test normal, replace the ECM.

2. Ignition ON, observe the DTC information with a scan tool. Verify DTCs P0601, P0603, P0604, P0606, P0607, P060D, P062F, or P16F3 do

not set this ignition cycle.

瀚慖f any of the DTCs set this ignition cycle, replace the ECM.

Circuit/System Description

This is an internal fault detection of the transmission control module. This fault is handled inside the transmission control module and no external

circuits are involved. The transmission control module is part of the control solenoid valve assembly, and is not serviced separately.

Conditions for Running the DTC

* The control solenoid valve assembly runs the program to detect an internal fault when the key is ON or the engine is running.
