Per eseguire l'autodiagnosi della centralina elettronica č necessario inserire la chiave ed accendere/spegnere il quadro per due volte, alla terza accensione del quadro, sul display dei Kilometri apparirā un numero, ad esempio "55". Scorrendo la lista dei codici sottostante si otterranno informazioni relative al codice mostrato, nel caso dell'esempio: Codice N° "55" = End of code. Trouble codes finished or none recorded.
Fine del codice. codici di errore finiti o nessun errore registrato.
in questo caso non ci sono problemi.
Codice, Descrizione e motivi probabili
12 Terminals 6 and 7 connected. If appears when terminals not connected and engine running, no signal between distributor and computer.
23 Charge air temp. sensor. Sensor input above or below acceptable voltage.
24 TPS voltage sensor input above or below the minimum acceptable voltage. Or TPS signal does not correlate to MAP sensor.
25 AIS motor circuits. An open or shorted condition detected in one or more of the IAC control circuits. Or target idle speed not met.
26 Peak injector current has not been reached or injector circuits have resistance
27 Injector # X control circuit Injector output driver does not respond properly to the control signal.
31 An open or shorted condition in Purge Solenoid circuit. Incorrect vapour flow detected. Possible leak or blocked between solenoid and fuel tank.
33 A/C clutch relay circuit An open or shorted condition detected in the A/C clutch relay circuit.
34 S/C solenoid circuits An open or shorted condition detected in the speed control vacuum or vent solenoid circuits. Voltage too high or low.
35 Radiator Fan Relay in open or shorted condition detected in the radiator fan relay circuit. ( 2.5L only ).
36 Air switch solenoid circuit (non-turbo) or the wastegate solenoid on turbocharged models
37 No speed difference detected at 3 to 4 shift or no lockup in torque converter. Problem with trans solenoid with wrong pressure or voltage. Speed to trans ratio below minium required. Park/Neutral switch stuck.
41 Alternator field circuit in open or shorted condition detected in the alternator field control circuit.
42 ASD ( auto shut down ) or fuel pump relay control circuit in open or shorted condition detected. Or no voltage sensed at controllers. No fuel sensor signal detected or changed over time at PCM.
43 Cylinder misfire detected.
44 Battery temperature voltage out of range ( too high or low ).
45 Trans temperature/ Governor pressure voltage out of range. Less than 1.55 or above 3.73volts for temperature and less than .1 or above 4.89 volts. Trans temp. to high or low. OD switch input too low for more than 5 mins.
46 Charging system voltage high. Battery voltage sense input above target charging voltage during engine operation.
47 Charging system voltage low. Battery voltage sense input below target charging voltage during engine operation.
51 O2 signal below centre. Oxygen sensor signal indicates lean fuel/air ratio condition during engine operation.
52 O2 signal above centre. Oxygen sensor signal indicates rich fuel/air ratio condition during engine operation or Adaptive memory at lean limit.
