Powertrain Diagnostic Trouble Code (DTC) Type Definitions (See: Diagnostic Trouble Code Descriptions/Powertrain Diagnostic Trouble Code

(DTC) Type Definitions)

Scan Tool Reference

Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information

Circuit/System Verification

1. Engine running for at least 1 minute.

2. Ignition OFF for 30 seconds.

3. Ignition ON, verify that DTC P0602 is not set.

瀚慖f the DTC is set, program the transmission control module (TCM). If the DTC resets, replace the control solenoid (w/body and TCM)

valve assembly.

4. Observe the DTC information with a scan tool. DTCs P0601, P0603, P0604, and P062F should not set.

瀚慖f a DTC sets, replace the control solenoid (w/body and TCM) valve assembly.

5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Repair Instructions

Important: Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and

Inspection/Programming and Relearning) any time a transmission related component is serviced.

Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptors

DTC P0601

- Control Module Read Only Memory Performance

DTC P0602

- Control Module Not Programmed

DTC P0603

- Control Module Long Term Memory Reset

DTC P0604

- Control Module Random Access Memory Performance

Circuit/System Description

This is an internal fault detection of the transmission control module (TCM). This fault is handled inside the TCM and no external circuits are

involved.

Conditions for Running the DTC

The TCM runs the program to detect an internal condition at key ON. The only requirements are voltage and ground. This program runs even if the

voltage is out of the valid operating range.
