Fault storage

Activation of the engine diagnosis indicator lamp (EURO3/4)

or CHECK ENGINE (MIL) malfunction indicator lamp

After expiry of test duration and fault

No activation

3

Checking frequency

Continuous

4

Checked signal or status

Current/ voltage test at variable intake manifold switchover valve

5

Fault setting conditions

Limit values

Short circuit to ground

Short circuit to positive

Line interruption

Voltage lower than 2.5 V

Current higher than 4.2 A

No voltage at variable intake manifold switchover valve

Approx. 4 to 8 V at output of ME-SFI control unit under no load.

6

Check prerequisites

Battery voltage between 8 and 17 V

7

Actuation of the variable intake manifold switchover valve is checked for to detect a cable breakage and short-circuit (to ground or battery voltage). A short circuit to ground and a line interruption will be detected when the output stages are locked, whilst a short circuit to the battery voltage will be detected when the output stages are conducting.

The output stage is immediately no longer activated when a fault arises.
