CAUTION
BEFORE CARRYING OUT ANY TROUBLESHOOTING,
CAREFULLY READ THE GENERAL TROUBLESHOOTING
CONCEPTS FOR ELECTRICAL DEVICES AT THE BEGIN-
NING OF THE CHECK AND CONTROL SECTION IN THE
ELECTRICAL SYSTEM CHAPTER.
DIAGNOSTIC TOOL: ACTIVATIONS
Front coil:
The secondary injection relay (no. 35 in the electrical circuit diagram, placed under the fuel tank, on the
right side of the filter housing. However, CHECK the relay identification with the cables colour - blue
taping) for 5 seconds and the pink coil cable is closed to ground for 2 ms per each second. It is rec-
ommended to disconnect the 4-way connector of the fuel pump to be able to hear the relay and injector
activation. Electrical continuity is required in the wiring for the relay to activate correctly: no errors are
generated in case of no activation.
