DTC P0658 or P0659

Diagnostic Instructions
    • Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
    • Review Strategy Based Diagnosis for an overview of the diagnostic approach.
    • Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

High Side Driver 1

P0658

P0658

P0659

Circuit/System Description

The transmission control module (TCM) high side driver (HSD) 1 is located inside the control solenoid valve assembly which has no serviceable components. The HSD 1 provides power to the TCM pressure control solenoids and shift solenoids. This fault is handled inside the TCM and no external circuits are involved.

Conditions for Running the DTC

P0658

    • HSD 1 is enabled.
    • DTC P0658 is not set.

P0659

    • DTC P0659 is not set.
    • The ignition transitions from OFF to ON.

Conditions for Setting the DTC

P0658

The TCM detects an internal open or short-circuit to ground in the HSD 1 circuit for 1 second.

P0659

The TCM detects an internal short-circuit to voltage on the HSD 1 circuit for 1 second.

Action Taken When the DTC Sets

P0658

    • DTC P0658 is a Type A DTC.
    • The TCM turns OFF all HSDs.
    • The TCM turns OFF all solenoids.
    • The TCM commands the torque converter clutch (TCC) OFF.
    • The TCM commands maximum line pressure.
    • The TCM freezes transmission adaptive functions.
    • The TCM inhibits the Tap Up/Tap Down function.
    • The TCM inhibits manual shifting of forward gears.
    • The TCM defaults the transmission to 5th gear and reverse.
    • The TCM enables torque management.

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.

Diagnostic Aids

When DTC P0658 sets, the line pressure control solenoid, and pressure control solenoids 2 and 3, will default to maximum pressure. This results in maximum line pressure to the 3-5 reverse clutch, and low/reverse clutch, when reverse is selected, and the 4-5-6 clutch, when forward is selected.

For equivalent regional tools, refer to Special Tools .

Circuit/System Verification
  1. Ignition ON, verify with a scan tool the High Side Driver 1 parameter displays ON.
  2. Engine Running, gear selector lever in Park position. Verify with a scan tool the following test status parameters displays OK.
    3. • High Side Driver 1 Circuit High Voltage Test Status
    • High Side Driver 1 Circuit Open Test Status
    • High Side Driver 1 Circuit Low Voltage Test Status
  3. After performing the above steps, verify that the DTC does not reset by operating the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions you observe from the Freeze Frame/Failure Records data. If the vehicle passes the Circuit/System Verification procedure, then STOP. Do not perform the Circuit/System Testing or Component Testing as this may result in an unnecessary part replacement. Refer to Testing for Intermittent Conditions and Poor Connections .

Circuit/System Testing

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

  1. Ignition OFF, remove the control solenoid assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Replacement .
  2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection .
  3. Place the control solenoid valve assembly on a clean work surface near the transmission assembly.
  4. Connect DT-48616-10 harness between the vehicle wire harness electrical connector, and the control solenoid valve assembly electrical connector.
  5. Ignition ON, verify with a scan tool the following test status parameters display OK.
    6. • High Side Driver 1 Circuit High Voltage Test Status
    • High Side Driver 1 Circuit Open Test Status
    • High Side Driver 1 Circuit Low Voltage Test Status
    ⇒If any test status parameter displays Fault or Malfunction, replace the control solenoid valve assembly.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

    • Refer to Control Module References for control solenoid valve assembly replacement, set-up, and programming.
    • Perform the Transmission Adaptive Values Learn following all transmission related repairs.
