CC.0 : short circuit to earth
CO.1 : open circuit or short circuit to + 12 V
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running or following a road test.
Special notes:
If the fault is present:
– the coolant temperature: PR064: Coolant temperature is fixed at 119°C,
– the preheating phase is greater than 10 seconds,
– the fan assembly is permanently supplied,
The level 1 warning light comes on.
Use bornier Elé. 1681 for any work on the computer connectors.
CC.0
NOTESNone.
Check the coolant temperature sensor connections.
Repair if necessary.
Measure the resistance of the coolant temperature sensor between terminals 2 and 3 of its black connector.
Replace the sensor if its resistance is not approximately: 12460±112Ω at -10°C
2252±112Ω at 25°C
811.4±39Ω at 50°C
283±8Ω at 80°C
115±3Ω at 110°C
Check the injection computer connections.
Check for continuity and the absence of interference resistance of the following connections:
Injection computer brown 48-track connector B, track F2 Track 3 coolant temperature sensor
Injection computer brown 48-track connector B, track H1 Track 2 coolant temperature sensor
Repair if necessary.
If the fault is still present, replace the coolant temperature sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.
