NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after several starting attempts, or with the engine running.
Special notes:
The level 1 warning light is lit for a fault that does not require you to stop the vehicle.
The level 2 warning light is lit for a fault which requires the engine to be switched off.
If 5.DEF is still present, the OBD warning light will come on after three consecutive
driving cycles (starting + 5 seconds + switch off the ignition and wait 40 seconds).
