3-54 FUEL SYSTEM (DFI)
Crankshaft Sensor (Service Code 21)
Start the engine and switch the diagnosis mode to Dealer
1 mode to know all the problem that the DFI system has at
the time of self-diagnosis. If the engine cannot be started,
the self-diagnosis system does not detect dynamic condi-
tion of the crankshaft sensor. In this case, turn off the igni-
tion switch and turn it on again to enter the Dealer 2 mode.
In this mode, the system tells all the troubles which the DFI
system had in both static and dynamic conditions.
