These bargraphs visualise the control of the various relays:
- Preheating relay N° 1.
- Preheating relay N° 2 (not used).
- Power assisted steering pump assembly relay (for AC + PAS).
- Altimetric corrector relay.

Warning light control
XR25 aid :BG 10LH is illuminated if the warning light on the instrument panel
is controlled. This bargraph is normally illuminated; it extinguishes
when the engine is running if there is no fault.

Vehicles fitted with power assisted steering but without air conditioning must
be configured to "without PAS".NOTES
These bargraphs show the computer configuration for the air conditioning and pump assembly power
assisted steering options.
Computers sold by the Parts Department are systematically configured for vehicles with air conditioning
and with the PAS pump assembly.
If the vehicle does not have air conditioning, use the command mode G50*4* to reverse the computer
configuration (the opposite command exists for configuring to "with AC": G50*3*).
If the vehicle is not fitted with a PAS pump assembly (vehicle without air conditioning), use command
mode G50*9* to reverse the computer configuration (the opposite command exists for configuring to
"with PAS": G50*8*).
NOTE : Vehicles fitted with power assisted steering but without air conditioning must be configured to
"without PAS".

Erase the computer memory (G0**), switch the ignition off, then carry out a road
test.
Finish the operation by checking using the XR25.

REPLACING THE COMPUTER
A)On these computers it is necessary to programme the load lever full load position (this value is required to
replace and adjust the load lever position potentiometer).
Programming procedure:
• Enter code G31* on the XR25 (engine speed zero)
• Press the accelerator pedal until the display flashes
"PF".
The display then shows "bon", "Fin" then "6/7.dlE" when the procedure has been carried out correctly.
Bargraph 12 RH side must be extinguished.
• Switch off the ignition.
B)Lucas digital DPC injection computers are sold pre-configured to "with air conditioning".
If the vehicle does not have air conditioning, use command G50*4* on the XR25 to programme "without
air conditioning".
Lucas digital DPC injection computers are sold pre-configured to "with power assisted steering" (with po-
wer assisted steering pump assembly).
If the vehicle does not have a power assisted steering pump assembly (vehicle without air conditioning),
use command G50*9* on the XR25 to programme "without power assisted steering".
Vehicles fitted with power assisted steering but without air conditioning must be configured to "without
power assisted steering".
REPLACING THE LOAD LEVER POSITION POTENTIOMETER
The load lever position potentiometer may only be replaced in After Sales if the full load position has been
programmed into the computer before the fault with the potentiometer.
Procedure for replacing and adjusting the load lever position potentiometer:
• Fit the new potentiometer into position without locking the mounting bolts.
• Connect the potentiometer and set up the XR25 (S8 code D34).
• Start command G32* on the XR25, keep the accelerator pedal fully depressed (do not touch the load lever
directly) and turn the potentiometer until the display on the XR25 shows a value other than H.L (outside li-
mits). Adjust the setting by turning the potentiometer to obtain 0 on the display.
• Tighten the mounting bolts with the potentiometer in this position then press * to complete the adjus-
tment procedure.
