DTC Descriptors

DTC P0658

Actuator High Control Circuit Group 1 Low Voltage

DTC P0659

Actuator High Control Circuit Group 1 High Voltage

Circuit/System Description

The transmission control module (TCM) high side driver 1 is located inside the control solenoid valve assembly which has no serviceable components. The high side driver 1 provides power to the pressure control solenoid valves and shift solenoid valves.

Conditions for Running the DTC

P0658

• DTC P0658 is not set.
• High side driver 1 is enabled.
• Runs continuously when above conditions are met.

P0659

• DTC P0659 is not set.
• Runs one time when ignition transitions from OFF to ON.

Conditions for Setting the DTC

P0658

TCM detects an internal open or short to ground in the high side driver 1 circuit for 1 s.

P0659

TCM detects an internal short to voltage on the high side driver 1 circuit for 1 s.

Action Taken When the DTC Sets

P0658

• P0658 is a Type A DTC.
• TCM turns the high side driver OFF.
• TCM commands all solenoids OFF.
• TCM commands the TCC OFF.

Circuit/System Verification

1. Ignition ON.
2. Verify the scan tool High Side Driver 1 parameter displays ON.

If ON is not displayed

Refer to Circuit/System Testing.

If ON is displayed

3. Engine Running and the gear selector lever in the Park position.
4. Verify the scan tool parameters listed below do not display Malfunction:

• High Side Driver 1 Circuit Low Voltage Test Status
• High Side Driver 1 Circuit Open Test Status
• High Side Driver 1 Circuit High Voltage Test Status

If Malfunction is displayed

Refer to Circuit/System Testing.

If Malfunction is not displayed

5. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
6. Verify the DTC does not set.

If the DTC sets

Refer to Circuit/System Testing.

If the DTC does not set

7. All OK.

Circuit/System Testing

NOTE: You must perform the Circuit/System Verification first.

1. Ignition OFF, remove the Q8 Control Solenoid Valve Assembly.
2. Verify the Q8 Control Solenoid Valve Assembly is not contaminated with any debris. Refer to Control Solenoid Valve and Transmission Control Module Assembly Inspection.

If contaminated

Repair as necessary.

If not contaminated

3. Verify the resistance is within the specified range for each solenoid listed in the Control Solenoid Valve and Transmission Control Module Assembly Inspection.

If the resistance is not within range

Replace the Q8 Control Solenoid Valve Assembly.

If the resistance is within range

4. Place the Q8 Control Solenoid Valve Assembly on a clean work surface near the transmission assembly.
5. Connect the DT-48616-10 adapter harness between the vehicle harness connector, and the Q8 Control Solenoid Valve Assembly connector. Ignition ON.
6. Verify the scan tool parameters listed below do not display Malfunction:

• High Side Driver 1 Circuit Low Voltage Test Status
• High Side Driver 1 Circuit Open Test Status
• High Side Driver 1 Circuit High Voltage Test Status

If Malfunction is displayed

Replace the Q8 Control Solenoid Valve Assembly.

If Malfunction is not displayed

7. All OK.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
