FLYWHEEL SIGNAL
NOTESThere must be no present or stored faults.
Information:
If the flywheel has been replaced or removed, reinitialise the flywheel target
programming.
Check the mounting and positioning of the TDC sensor (see MR 364 Mechanics, 10A, Engine and
peripherals).
Repair if necessary.
Check the cleanliness and condition of the TDC sensor and its connections.
Check the condition of the wire.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer, connectorB, track E4 Track 2 of the TDC sensor
Injection computer, connectorB, track F3 track 1 of the TDC sensor
Repair if necessary.
Measure the resistance of the TDC sensor between tracks 1 and 2.
Replace the sensor if the resistance is not 200 to 270 at 23 °C.
If the sensor has been replaced, reset the flywheel signal programming.
Flywheel signal programming reinitialisation procedure:
Accelerate up to 4000 rpm in third gear ratio, then decelerate to power take-up speed*.
Then repeat immediately.
(* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.)
If the fault is still present, check the cleanliness and condition of the flywheel.
AFTER REPAIRIf the TDC sensor has been replaced, reinitialise the programming (RZ005).
Repeat the conformity check from the start.
