FUNCTION
The Motronic Engine Control Module (ECM) -J220- for the fuel injection and ignition system is equipped with Diagnostic Trouble Code (DTC) memory.

If malfunctions occur in the sensors and components being monitored, they will be stored in DTC memory together with an indication of the type of malfunction.

The stored malfunctions are output by checking DTC memory.

After malfunctions have been eliminated DTC memory must be cleared.

The readiness code must be created again after each time the DTC memory is cleared, and when the voltage supply to ECM -J220- is interrupted.

NOTE: The On Board Diagnostic (OBD) system only monitors a part of the fuel injection and ignition systems. For troubleshooting also use the "Electrical Wiring Diagrams, Troubleshooting & Component Locations" binder.
