Specific tooling
020680Y Diagnosis Tool
The tester pages display the list of errors detecta-
ble by the auto-diagnosis.
Errors detected by the auto-diagnosis are marked
by one or two reference dots.
They are arranged on two lines:
Line A = current failures (present)
Line M = stored failures
Errors detectable by the auto-diagnosis may refer to the following system circuits or sectors of the
control unit:
- Throttle valve position signal
- ambient pressure signal
- coolant temperature signal
- intake air temperature signal
- wrong battery voltage
- Injector and relevant circuit
- HV coil and relevant circuit
- Stepper and relevant circuit
- Pump relay circuit
- Electric fan relay circuit
- RAM memory
- ROM memory
- EEPROM
- Microprocessor
- Signals panel (stroke - revolution signal - unsteady cycle)
Underlined failures cause the engine to stop.
In the other cases, the engine works managed by the basic data.
