AD07.13-D-6000B | Diesel injection system (EDC) electrical test | 15.5.97 |
ENGINE 602.980 in MODEL 901.###, 902.###, 903.###, 904.### ## up to 614658 up to 31.5.96
| Diesel injection system (EDC) Diagnosis, basic knowledge | ||
| Battery voltage 11 up to 14 V | ||
| HHT connected to diagnostic socket | ||
| Remove left headlamp unit | ||
| 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 complete (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. | ||
