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.
