CONDITIONS FOR STARTING THE ENGINE SATISFIED
NOTESNo particular instructions.
In the Keyless vehicle function, check that the starting conditions are met.
The UPC participates in the engine start function by managing the switches on the gearbox.
Check the operation of the gearbox switches using statuses ET004 Reverse gear selected and ET005
Manual gearbox gear lever position then run fault finding on UCH start and engine management functions.
If the conditions have been satisfied and the starter does not work, refer to ALP 2.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic

ALTERNATOR CHARGE
NOTESCheck in the configuration readings that the alternator type has been configured
correctly.
When the engine has stopped, the value must be constant and greater than 98 %.
