Check the cleanliness and condition of the UCH computer connections.
Repair if necessary.
Disconnect connector MN of the Protection and Switching Unit.
Check the cleanliness and condition of its connections.
Use the "Universal bornier" to check the insulation and continuity on the following connection:
Injection computer, connectorB, track D4Protection and Switching Unit, connector MN,
track 5
Repair if necessary.
If the fault is still present, carry out fault finding on the Protection and Switching Unit system (See87G, Engine

–Type 5 defect mode: ESP and the cruise control/speed limiter are deactivated and
the vehicle stalls at idle speed.
Check the cleanliness and condition of the manifold pressure sensor and its connections.
Repair if necessary.
If the fault is still present, check for + 5 V on track H2 and for earth on track H4 of connectorB of the injection
computer.
Contact the Techline if it is not correct.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
