Diagnostic Check






DIAGNOSTIC CHECK
This test determines if the transmission itself or its inputs or outputs connections or sensors are failing.
1. Connect the TECH 1: GO THROUGH TECH1 OBD II CONNECTION.
2. Turn on the ignition but not the engine.
3. Push "F2" on TECH1 to see the Diagnostic Trouble Code (DTC):
4. IF you have DTC?
YES: write down all code numbers and do the DTC CHECK
NO: the DTC can not help you finding the problem.
- GO THROUGH "CHECK TRANS" CHECK
- 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 Powertrain Control Module (PCM).
