Try to illuminate BG 5RH when the starter is activated.
BG 5RH is often seen to flash if *25 = dEF as its permanent illumination is very
quick. In certain cases, BG 5RH may illuminate then extinguish.
NOTES
Check the resistance of the target sensor.
Replace the sensor if necessary.*25 = CO.0
*25 = CC.0
Check the condition of the flywheel, especially if it has been removed.
The fault persists! Replace the injection computer.
IMPORTANT: The computer has probably been damaged by an electric shock.
The cause of the damage must be found before fitting a new
computer.
Check the target sensor has been correctly connected (the sensor connector must
not be inverted).
Repair if necessary.*25 = In
The fault persists! Replace the sensor.

STARTING FAULTS
Only refer to this customer complaint after a complete check using the XR25.
NOTES
Erase the computer memory using G0** and carry out a road test.
Check there is fuel present
(fuel gauge faulty).
Check the fuel is of the correct type.
Check the hosesCheck no hoses are pinched
(especially after a removal operation).
Disconnect the pipe connecting the canister bleed solenoid valve
to the inlet manifold.
Plug the pipe to prevent an air leak.
If there is no other effect, the canister bleed is faulty.
