control solenoid valve assembly.

6. 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) following all transmission related repairs.

* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:

Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General

Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).

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

DTC Descriptors

DTC P0641

- 5 V Reference 1 Circuit

DTC P0651

- 5 V Reference 2 Circuit

DTC P0697

- 5 V Reference 3 Circuit

DTC P06A3

- 5 V Reference 4 Circuit

Circuit/System Description

The engine control module (ECM) has 4 5 V reference circuits. The ECM provides the 5 V reference to various sensors. Each reference circuit

provides a 5 V reference for more than one sensor. An open, short to ground, or short voltage on one of the 5 V reference circuits can affect all the

components connected to that 5 V reference circuit. The ECM monitors the voltage on the 5 V reference circuits.

Conditions for Running the DTC

DTCs P0641, P0651, P0697, P06A3 run continuously when the ignition is ON.

Conditions for Setting the DTC

The 5 V reference circuit voltage is greater or less than a predetermined threshold.

Action Taken When the DTC Sets

DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.

Conditions for Clearing the DTC

DTCs P0641, P0651, P0697, and P06A3 are Type A DTCs.
