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.
