If BG 3RH is flashing, increase the engine speed to 2500 rpm for 5 minutes
If BG 3RH becomes permanently illuminated, deal with the fault.
NOTES
Check the connection and the condition of the connector on the oxygen sensor.
Check, ignition on during the timed phase, for :
-earth on track B of the oxygen sensor,
-+ 12 V after the fuel pump relay on track A of the oxygen sensor.
Repair if necessary.
Check for the presence of earth on track 4 on the injection computer.
Repair if necessary.
The fault persists. Replace the oxygen sensor.
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.

Try to illuminate BG 5RH when the starter is activated.
BG 5RH often seen to flash if *25 = dEF as its permanent illumination is very quick.
In certain cases, BG 5RH may illuminate then extinguish.
