Before performing a road test, configure and setup the scan tool for snapshot mode. This will allow you to display, monitor, and verify multiple

transmission data parameters at one time, after the road test.

For equivalent regional tools, refer to Special Tools (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Tools and

Equipment/6L45/6L50/6L80/6L90 - Automatic Transmission).

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.

3. Engine idling in Park, verify with a scan tool the Transmission ISS/OSS supply voltage test status parameter displays OK.

4. Engine idling in Park. Observe the Transmission ISS parameter on the scan tool, while varying the engine speed. The Transmission ISS

parameter should vary with engine speed and not drop out.

5. Operate the vehicle at 16-32 km/h (10-20 mph) while observing the Transmission OSS parameter on the scan tool. The Transmission OSS

parameter should vary with the vehicle speed and not drop out.
