Chart 2IDLE SPEED TOO HIGH (WHEN AIR CONDITIONING NOT
REQUESTED)
This fault may be connected to fast idle operation.
Check the condition of the pneumatic circuit for the fast idle solenoid valve.
Look for a short circuit to + 12 volts of the connection between track 11 on the injection computer and
track 20 on the BE connector for the air conditioning computer ("AC Inj. / fast idle" information).

Chart 3NO FAST IDLE WHEN AIR CONDITIONING REQUESTED
Only consult this customer complaint after a complete check using the XR25.
Look for an open circuit or a short circuit to earth on the connection between track 11 on the injection
computer and track 20 on the BE connector for the air conditioning computer ("AC Inj. / fast idle" infor-
mation).
This fault causes the absence of illumination of bargraph 9 LH side "air conditioning requested".

This vehicle is not fitted with ADAC at the moment.
If another bargraph is illuminated, refer to the fault finding for that bargraph.NOTES
If your vehicle has ADAC,
this method of fault finding will not be of use for this fault.
This bargraph is often illuminated or flashing in the following cases:
-Air conditioning compressor command mode G12*.
-Fault on fuel pump relay circuit.
-Other cases, which have not yet been noted, may well exist.

Connect the bornier in place of the computer and check the insulation and continuity of line 51 on the
computer.
Repair if necessary.
Check that the vehicle has air conditioning and if it is not fitted with air
conditioning, deal with the other bargraphs first.
Engine running, select the air conditioning function.
