CVT VERIFICATION TEST

Perform the following after completion of a diagnostic repair

1. Reconnect any disconnected components.
2. With the scan tool, erase all Transmission and Engine DTCs.
3. If the Transmission Control Module or the Transmission has been repaired or replaced, it is necessary to perform the scan tool Initialize CVT Re-learn Procedure. Refer to «STANDARD PROCEDURE»(ref-304335-S25493952562008110700000) .
4. With the scan tool, display Transmission Temperature. Start and run the engine until the transmission temperature is HOT, above 43° C or 110° F.
5. Check the transmission fluid and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure. CAUTION: The CVT uses a specific transmission fluid type that is green in color. Do not use a standard ATF fluid. Doing so can damage the transmission. Make sure to follow the Service Information fluid type and fill procedure.
6. Road test the vehicle. With the scan tool, monitor the engine rpm and throttle angle. Drive the vehicle from a standing start to 45 mph with a constant throttle opening of 20 to 25 degrees with an engine speed above 450 rpm.
7. For a specific DTC, drive the vehicle to the Symptom's When Monitored/When Set condition to verify the DTC is repaired.
8. If equipped with AutoStick®, upshift and downshift several times using the AutoStick® feature during the road test. NOTE: Use the OBDII task manager to run a Good Trip. This will confirm the repair(s) made and to ensure the DTC has not re-matured.
9. Check for any Diagnostic Trouble Codes (DTCs) during and after the road test.

Did any Diagnostic Trouble Codes set during the road test?

Yes

1. Repair is not complete. Refer to the Transmission DTCs and perform the appropriate symptom(s). See «DIAGNOSIS AND TESTING»(ref-304346-S25968872092008110700000) .

No

1. Repair is complete.
