Summary

. INFORMATION To properly diagnose the customer's complaint, the applicable test plan for the misfire faults stored in the DME must be performed to avoid repeat repairs. If a misfire fault is not stored in the DME memory and an engine related drivability complaint is received, follow the path below to manually start the misfire test plan (AT1214_TVD4_MISFIRE_20): 1. Perform a vehicle test. 2. Select "Function Structure." 3. Select "01 Engine." 4. Select "Engine electronics MEVD." 5. Select "Misfire detection." 6. Follow the steps in the test plan and select "Basic check (start)" first. Do not select "Additional check" at this time. 7. If the result of the "Basic check" indentifies a fuel system component failure, replace the identified component. If the result of the "Basic check" test plan was inconclusive, go to step 7. After the component replacement, perform the "Basic check" portion of the test plan again to verify if the diagnosis was correct and the vehicle condition has been rectified.
