Scan Tool Reference

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

Circuit/System Verification

1. Ensure the transmission fluid temperature is between 50-80掳C (122-176掳F).

2. Operate the vehicle in 2nd gear long enough to ensure at least a 3掳C (5掳F) rise in transmission fluid temperature, then operate the vehicle in

Park for 5 s.

3. Observe the scan tool data Clutch Pressure Control Solenoid Valve 1 Current parameter, the reading should be between 0.1-1.1 A.

Circuit/System Testing

Command the Clutch Pressure Control Solenoid Valve 1 with a scan tool. The value should change from 0.0-1.0 A.

If the value does not change, turn ignition OFF, remove the K71 Transmission Control Module. Connect a test lamp between the low reference

circuit terminal 10 X2 at the K71 Transmission Control Module and the voltage supply component circuit terminal 11 X2 at the K71 Transmission

Control Module. Command the Clutch Pressure Control Solenoid Valve 1 with a scan tool. The test lamp has to illuminate brighter with increasing

current.

If the test lamp always illuminate or always does not illuminate, replace the K71 Transmission Control Module.

Component Testing

Dynamic Test

1. Perform the line pressure check. Refer to Line Pressure Check (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Testing and Inspection/Symptom Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Line Pressure

Check).

瀚慖f the line pressure check fails, replace the control valve body.

2. Verify the line pressure check does not fail.

瀚慖f the line pressure check fails, replace the replace the K71 Transmission Control Module.

3. Perform the Control Solenoid Valve Inspection (M36 and MXE) (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/AF40-6 - Automatic Transmission).

瀚慖f the inspection fails, replace the control valve body.

4. If all circuit test normal, replace the K71 Transmission Control Module.

Repair Instructions

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

* Control valve body replacement-Refer to Control Valve Body Replacement (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Valve Body/Service and Repair/AF40-6 - Automatic Transmission/Control Valve Body Replacement).

* TCM-Refer to Control Module References (See: Testing and Inspection/Programming and Relearning).

* Perform the Transmission Adaptive Functions (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Description and

Operation/AF40-6 - Automatic Transmission/Transmission Adaptive Functions).
