I have a C4 Grand Picasso Diesel Auto 1.6 2013 and only have done 7700 miles.
Suddenly the Start Stop function has stopped working. The ECO light flashes
three times and nothing happens. The battery is fully charged and noting is
draining the battery. I have already checked all requirements for the function
to work to be ok. I have a Autel Maxidas d708 and it throws error A4D4 Fault:
Rear door sills or boot lighting fault : Short circuit to positive ,
I have checked all connections and lights to be working and nothing appears
to be short circuit. However on further diagnosis I found that in BIS system
one item failed ( Number plate illumination control Actuation failed ), however
the lights are working. The rest of functions on car are all ok. The DTC code comes back upon clearing.
Please help. Thanks in advance.
