NOTESSpecial notes:
If this fault appears during the engine starting phase, followed by a high idle speed
(warm engine), check the conformity of the alternator and its configuration in the UPC
according to the procedure below:
– Check that the part number of the alternator fitted on the vehicle conforms with the
part number in the World Vehicle Database.
– Using the CLIP tool, in the UPC field, check that the alternator's configuration CF001
Alternator type corresponds with the alternator fitted on the vehicle (and the World
Vehicle Database).
This last stage is only possible on first generation UPCs (in Vdiag 44). Second
generation UPCs (Vdiag 48 and higher) are self-configured.
Run a multiplex network test (see88B, Multiplex).
