FAILURE CODE DECODING
G-Drive appliance
The emission of the anomaly codes detected during self-testing and
stored in the ECU starts after pressing and releasing the BP1 push-
button on the Interconnection Electrical Unit.
The LED LD1 will signal, with two series of emissions at different
frequencies, the blink codes that indicate the anomaly with decimal
numbering.
Slow blinks identify the area of the anomaly (engine, injectors, etc.), fast
blinks identify a specific anomaly.
Every time the push-button is pressed and released, only one of the
stored codes is emitted; therefore, the procedure must be repeated
until an error indication identical to the first one is obtained, which
means the entire error memory has been analyzed.
If no anomalies are stored, the light comes on when the push-button
is pressed and comes off about 1 second after its release, without any
subsequent blinking.
