NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears when the engine is running and the gear lever is at P.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Disconnect the battery.
Disconnect the modular connector and check the cleanliness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connections:
●connection code 5DA, between components 119 and 1017,
●connection code 5DB, between components 119 and 1017.
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 the wiring.
Reconnect the modular connector.
Measure the resistance of component 1017 between the following connections:
●connection code 5DA,
●connection code 5DB.
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 the wiring.
Replace the sensor or the wiring harness if the resistance is not: 300 Ω ± 40.
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
