Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
Check the pre-postheating unit connections.
Check the connections on all the heater plugs.
Repair if necessary.
Check fuse F2 (70A) on the power supply fuse board.
Check the resistance of the heater plugs:
Replace any plug whose resistance is not below 2 Ω at + 20˚C.
Check the continuity and absence of interference resistance of the following connections:
preheating unit track 1 cylinder 3 heater plug
preheating unit track 2 cylinder 1 heater plug
preheating unit track 6 cylinder 4 heater plug
preheating unit track 7 cylinder 2 heater plug.
Check for presence of + 12 V on track 4 of the pre-postheating unit (via fuse F2, 70A).
If the fault is still present,
Check the injection computer connections.
Check the following connections for continuity and make sure there is no extraneous resistance:
Injection computer grey 32-track connector C, track A4 track 3 preheating unit connector
Injection computer grey, 32-track connector C, track E2 track 8 of the preheating unit connector
If the fault is still present, replace the pre-postheating unit.
