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

* Transmission ISS

* Transmission OSS

* Vehicle Speed

* Shift Solenoid 2

* TFP Switches

5. Record the Freeze Frame/Failure Records data. Clear the DTCs.

6. Engine running, brakes applied, transmission gear shift selector in reverse. Shift to drive and accelerate to 56 km/h (35 mph) with calculated

throttle position greater than 15 percent. Perform this test 5 consecutive times. The DTC should not set.

7. Operate the vehicle within the Condition for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Perform the Line Pressure Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component

Tests and General Diagnostics/6L45/6L50/6L80/6L90 - Automatic Transmission/Line Pressure Check). Verify the transmission line

pressures are within the specified ranges.

瀚慖f not within the specified ranges, refer to Fluid Pressure High or Low (See: Transmission and Drivetrain/Automatic
