1.DEF : relay cut out too soon
2.DEF : relay cut out too late
NOTESConditions for applying the fault finding procedure to a stored fault:
Only deal with this fault if it is stored.
Special notes:
The main relay is integrated into the UPC.
Use bornier Elé. 1681 for all operations on the injection computer connectors.
Check the Protection and Switching Unit connections.
Check the injection computer connections.
Repair if necessary.
Check the condition of the battery terminals making sure they are correctly tightened.
Repair if necessary.
Check for continuity and the absence of interference resistance on the following
connection:
Injection computer connector B,
brown 48-track track E1 Track D2 UPC brown connector D.
Repair if necessary.
IMPORTANT!If the fault is still present and remains present, refer to the Protection and Switching Unit
Technical Note.
WARNING
If the UPC no longer detects the injection computer frames then GMV 1 will be
started until the battery has been completely discharged.
In the event that engine cooling fan 1 is not working, GMV 2 will be supplied.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.
