In the event of a fault, look for any damage to the wiring and check the condition and connection of the connectors
for components 119 and 129.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the continuity and insulation of the following connection:
●connection code 5DU,
between components 119 and 129.
Check for + after ignition feed on connection BP42 of component 119.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
