Diesel injection system (EDC) Diagnosis, basic knowledge | |||
| Battery voltage 11 up to 14 V | ||
| HHT connected to diagnostic socket | ||
Connect test wiring harness with socket box at control unit according to connection diagram. | Do not unplug control unit sockets unless ignition switched off | ||
| Electronic distributor-type fuel injection system (all connectors connected) | ||
| Cables, connectors and plug connectors are covered by the test with the HHT and may need to be tested again separately, if a fault is displayed, for open circuit, good contact and correct connection on the basis of the valid wiring diagram. | ||
