* Switch Signal C terminal C
* Switch Signal P terminal B
瀚慖f not the specified value, replace the control solenoid valve assembly.
7. Connect a 3-amp fused jumper wire between park/neutral switch signal circuit terminal F and IMS ground circuit terminal A on the TCM
assembly. Verify the ECM PNP Switch parameter changes from IN Gear to Park/Neutral.
瀚慖f not the specified value, test the park/neutral signal circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
8. If all circuits test normal, replace the IMS.
Repair Instructions
Note:
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning) following all transmission related repairs.
* 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) before replacing the TCM.
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
