1.DEF : Internal electronic fault
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched off and back on.
If the fault is stored, clear the fault, switch off the ignition and disconnect the F8 (15A) fuse of the UCH supply
(component code 645) on the passenger compartment fuse and relay box (component code 1016).
–Refit the fuse and switch the ignition back on.
–Request locking and then unlocking, then start the engine.
Check the condition and connection of the PE1, PE2 and PE3 connectors of the UCH (component code 645)
(tabs pushed back, oxidised, broken).
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check for + after ignition feed on connection AP43 of component 645.
Check for + accessories feed on connection SP2 (for vehicles fitted with a manual gearbox) or SP15
(for vehicles fitted with a sequential gearbox) of component 645.
Check for earth on connection NAM of component 645. Check the earth on connection MAM of component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault reappears as stored, contact Techline.
If the fault does not reappear, switch the lighting, wipers, vehicle locking and climate control request controls on
and off several times, then read the faults again.
If the fault is still present. Do not operate on the computer, contact Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline): reconfigure the new
UCH (see Configurations and programming).
Deal with any other faults.
