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/6L45/6L50/6L80/6L90 - Automatic Transmission/Transmission Fluid Level and
Condition Check) to verify correct fluid level and condition.
Note: Perform a scan tool snapshot, during the road test.
3. Perform the Road Test (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Initial Inspection and
Diagnostic Overview/6L45/6L50/6L80/6L90 - Automatic Transmission/Road Test). Verify the transmission operation performs as indicated
in the road test instructions.
4. Review the scan tool snapshot transmission data parameters. Verify the engine and transmission data parameters display the correct values in
all forward gear ranges:
* Engine Speed
* Vehicle Speed
* Transmission ISS
* Transmission OSS
* Shift Solenoid Valve 1
