Results of the tests
0PRELIMINARY CHECKSAll OKProblems metOperation
Preliminarily check that there is fuel in the tank and, if necessary, operate the inertia switch

Then check:

  • that there is no water, other fluid or dirt in the fuel tank
  • the state of the spark plugs and leads
  • the condition of the air intake circuit
  • for a possible obstruction in the catalyzer
 Continue to Step 1 Presence of dirt in the fuel tank Clean the fuel tank Op. 1040A24
Spark plugs dirty or damaged Clean or replace the spark plugs Op.   5510D10 
Spark plug leads damaged Replace spark plug leads Op.   5510D14 
Air intake circuit component damagedReplace component (See Assembly 1048A)
Catalytic converter obstructed Replace catalyzer Op.   1080B62 
1CHECK I.E. AND CODE FAILURE WARNING LIGHTSAll OKProblems metOperation

Place the key in the ON position and check that:

  • the i.e. failure warning light comes on for about 4 seconds and then goes out.
  • the CODE warning light comes on for less than a second and then goes out
 Continue to Step 2 The i.e. failure warning light comes on and remains on See table   K50 
The CODE warning light comes on and remains on See table   K52 
Both the warning lights come on and remain on See table   K56 
The i.e. failure warning light does not come on See table K53
The CODE warning light does not come on See table   K55 
2CHECKING WITH DIAGNOSTIC EQUIPMENTAll OKProblems metOperation
Connect diagnostic equipment (Examiner or other instruments) to the diagnostic socket.

Verify:

  • that there are no faults in the engine management control unit
  • the plausibility of all the parameters
 Continue to Step 3 An error is detected in the control unitContinue following the instructions for the diagnostic equipment
Lack of dialogue with the control unit Restore connection between the engine management control unit and the diagnostic connector ( See   E5030  PETROL ENGINE ELECTRONIC MANAGEMENT ).
No control unit connection to earthRestore the connection
