Active diagnosis

The Fiat/Lancia Tester can be used to run the following tests:

• Injector
• Fuel vapour cut-off solenoid
• Rev counter
• Idle speed actuator
• Error deletion.

Recovery

In the event of sensor malfunction, the ECU replaces the value transmitted by the sensor with a 'Recovery' value. This is stored in the ECU for use in the case of certain faults or may be reconstructed approximately on the basis of other available information, thus allowing the vehicle to be driven to a service centre.

The value is also relayed to the Fiat/Lancia tester, and therefore it should be noted, when diagnosing, that in the event of a malfunction, the Fiat/Lancia tester indicates an error in the affected sensor and displays the recovery value.

Permanent memory

The control unit has a permanent memory, which keeps a record of the error even after its cause has been eliminated, or after the key has been turned to STOP; and a temporary, volatile memory (RAM), which loses error details as soon as the underlying cause has been removed.

This will allow more effective identification of occasional errors.

Before completing tests on «permanent» memory content, delete using a Fiat/Lancia Tester in Active diagnosis mode.

Otherwise, when reconnected, the tester will still display errors from a previous diagnosis.

Disconnecting the control unit from the system, even for a long period, does not delete the "permanent" memory.
