ENGINE OPERATION
NOTESSpecial note:
This signal comes from the injection computer and is transmitted to the Electric Power
Assisted Steering computer via the multiplex network.
STOPPED:The engine has not yet been started, or has been stopped normally with the starter
button.
STALLED:The engine has been stopped, but it stopped abnormally, without using the starter button.
This status may appear for a brief moment during a normal engine stop.
RUNNING:The engine is currently in operation.
STARTING:The engine is currently being activated by the starter.
If the status does not correspond to the actual operation of the engine, carry out fault finding on the multiplex
network (see 88B, Multiplexing) and on the injection (see 13B, Diesel injection and 17B, Petrol injection)
using the diagnostic tool.
AFTER REPAIRPerform a test using the diagnostic tool.
