4. Do you have a DTC?
YES: write down all code numbers and do the DTC CHECK
NO: the DTC can not help you find the problem.
1. GOTHROUGH "CHECK TRANS" CHECK
2. IF it is flashing and the flash is 0.2 seconds ON and 0.2 seconds OFF, this means that you should have a DTC stored. Please recheck GOTO DIAGNOSTIC CHECK and if you find the same problem, replace the Powertrain Control Module (PCM).
