Circuit/System Verification
Note: If other DTCs are set, diagnose those DTCs first.
1. Engine idling in Park, with parking brake applied and drive wheels chocked.
2. Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing
and Inspection/Initial Inspection and Diagnostic Overview/Transmission Fluid Level and Condition Check) to verify correct fluid level and
condition.
3. Perform the Control Solenoid Valve and Transmission Control Module Assembly Cleaning (See: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/Control Solenoid Valve and Transmission Control
Module Assembly Cleaning) to dislodge debris and free up the valves.
Note: Perform a scan tool snapshot, during the road test.
4. Perform the Road Test (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Initial Inspection and
Diagnostic Overview/Road Test). Verify the transmission operation performs as indicated, in the road test instructions.
5. Review the scan tool snapshot transmission data parameters. Verify the engine and transmission data parameters display the correct values in
