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.

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.

STOREDCOMPUTER SUPPLY VOLTAGE
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after several starting attempts, or with the engine running.
Special notes:
Computer operating voltage: 9 V < operating voltage < 16 V.
If the battery voltage is too low this may cause the level 1 fault warning light to
come on.
It is then not possible to start the engine.
Use bornier Elé. 1681 for all operations on the injection computer connectors.
Check for continuity and the absence of interference resistance on the following connection:
Injection computer connector A, black 32-track track D1 Track 1 black connector of the UPC
Repair if necessary.
Check the condition of the FD5 fuse on the UPC (poor contact, or oxidation on the relay mounting clips).
Repair if necessary.
If the fault does not recur, start the engine and wait 1 min.
Carry out a road test and check the system faults.
If there are no faults, fault finding is complete.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.

Check the brake pedal switch connections.
Check the condition and adjustment of the brake pedal switch.
Repair if necessary.
Check the conformity of the brake switch:
Brake pedal released: continuity between tracks 3 and 4
infinite resistance across tracks 1 and 2
Brake pedal depressed: infinite resistance between tracks 3 and 4
continuity between tracks 1 and 2.
Replace the switch if necessary.
Check the condition of the 1H 15A fuse on the passenger compartment fuse and relay board.
Replace the fuse if necessary.
Check the following switch supplies:
+ 12 V after ignition Track 2 of the brake pedal switch connector
+ 12 V battery Track 4 of the brake pedal switch connector (via the UCH)
Replace the switch if necessary.
Check the continuity and insulation of the following connection:

overpressure valve.
Repair if necessary.
Measure the resistance of the flow regulator between tracks 1 and 2.
If the resistance is not 3Ω ±1 at 20°C, replace the injection pump.
Check the continuity and insulation from earth of the following connection:
Injection computer brown 48-track connector B, track M4 Track 2 of the fuel flow regulator
With the ignition on, check for + 12 V after relay feed on track 1 of the fuel flow regulator.
If the fault is still present, replace the injection pump.
