Checking the injector wiring
Tools:
88890074 Multimeter
1 NOTICE! Turn the starter key to the stop position.
2 Turn the main switch off.
IMPORTANT!
The
system must be disconnected from system voltage
and the
starter key must be in position 0 when the engine
control unit connector is disconnected or connected.
3 Remove the connector from the engine control unit.
Move the lock catch (1) upwards and pull the con-
nector (2) out.
4 Use multimeter 88890074 to measure the resist-
ance in the engine cable’s black (upper) connector
for the injectors.
IMPORTANT!
Be very careful when measuring inside the connector,
to ensure that no pin is damaged.
NOTICE! The measurement should exclude short cir-
cuiting or open circuit in the cable to the injector.
