If the voltage returns to normal after the coolant pressure sensor is disconnected,
Check the insulation against + 12 V of the following connection:
– Connection code 38Y between components 120 and 1202.
If the fault is still present, check the conformity of ET413 Cruise control/speed limiter function
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Clear the faults created by the multiple disconnections.
Carefully examine the engine management computer connections (for conductive particles, bent pins).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.
