If the bulbs light but the system does not perform initialisation and no communication is possible, perform the
following checks:
Remove the timed power supply 40A relay A located in the passenger compartment fuse and relay box.
Check the condition of the connections and repair if necessary.
Measure the following resistance values:
–Power circuit: Resistance between tracks 85 and 86 of the relay.
If the resistance is not 65 ± 5 ΩΩ Ω Ω
, replace relay A.
–Control circuit: Resistance between tracks 30 and 87A of the relay.
If the resistance is not approximately 1 ΩΩ Ω Ω
, replace relay A.
Check the battery voltage and carry out the operations necessary to obtain a suitable voltage (9.5 V < battery
voltage <14.4 V).
Check for:
a + 12 V supply before ignition on track 16 of the diagnostic socket,
a + 12 V supply after ignition on track 1 of the diagnostic socket,
