DTC Descriptors

DTC P0658
- Solenoid High Control Circuit Group 1 Low Voltage

DTC P0659
- Solenoid High Control Circuit Group 1 High Voltage

Circuit/System Description

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

Conditions for Running the DTC

P0658

* DTC P0658 is not set.

* High side driver 1 is enabled.

P0659

* DTC P0659 is not set.

* 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 for 1 s.

Action Taken When the DTC Sets

P0658

* DTC P0658 is a Type A DTC.

* TCM turns the high side driver OFF.

* TCM turns OFF all solenoids.

* TCM commands maximum line pressure.

* TCM freezes transmission adaptive functions.

* TCM commands the torque converter clutch (TCC) OFF.

* TCM inhibits Tap Up/Down function.

* TCM inhibits manual shifting of forward gears.

* TCM limits the transmission to Reverse and 5th gear operation.

* TCM requests a reduced torque value based on input speed.

P0659

DTC P0659 is a Type C DTC.

Conditions for Clearing the DTC

* DTC P0658 is a Type A DTC.

* DTC P0659 is a Type C DTC.

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 transmission in Park.

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 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 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 47825-20 - adapter harness between the vehicle wire harness electrical connector and the Q8 Control Solenoid Valve Assembly electrical 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.
