Diagnostic Aids

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.

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/Component Tests and General Diagnostics/6T70/6T75 - Automatic Transmission/Transmission Fluid Level and Condition

Check) to verify correct fluid level and condition.

3. Monitor the TFP Switch 4 parameter with a scan tool. Place the gear select lever in Park, Reverse, and Neutral range. Verify the TFP Switch

4 parameter states are correct for Park, Reverse, and Neutral. Refer to Transmission Fluid Pressure Switch Logic (See:

Specifications/Mechanical Specifications/Automatic Transmission/Transaxle/System Specifications/6T70/6T75 - Automatic

Transmission/Transmission Fluid Pressure Switch Logic).

4. Place the gear select lever in Drive range. Command the shift transmission with a scan tool through all forward ranges. Verify the TFP

Switch 4 parameter states are correct for all forward ranges. Refer to Transmission Fluid Pressure Switch Logic (See:

Specifications/Mechanical Specifications/Automatic Transmission/Transaxle/System Specifications/6T70/6T75 - Automatic
