When reading Diagnostic Trouble Codes thru the MIL, the
following conditions apply:
• The flashing MIL is on for 0.4 second and off for 0.4
second.
• The MIL is off for 1.2 seconds between digits of two
digit DTCs.
• The MIL is off for 2.4 seconds between DTCs.
• Each DTC repeats 3 times before the next stored DTC
begins flashing.
• Up to 6 DTCs can be stored.
• Once all stored DTCs are flashed, the process repeats
with the first stored DTC.
• DTCs are stored in the order in which they were set.
CLEARING TROUBLE CODES
To clear the trouble codes from the ECM, the electrical
current running to the ECM must be shut off. To do this,
disconnect the negative terminal from the battery for a
period of approximately 15 minutes.
Engine Module and Sensors
CRANKSHAFT POSITION (CKP) SENSOR
The crankshaft position (CKP) sensor provides a signal
used by the Engine Module to calculate the ignition
sequence. The CKP sensor initiates the reference pulses
which the Engine Module uses to calculate RPM and
crankshaft position.
CAMSHAFT POSITION (CMP) SENSOR AND
SIGNAL
The camshaft position (CMP) sensor sends a CMP signal
to the Engine Module. The Engine Module uses this signal
as a "sync pulse" to trigger the injectors in the proper
sequence. The Engine Module uses the CMP signal to
indicate the position of the #1 piston during its power
stroke. The CMP uses a Hall Effect sensor to measure pis-
ton position. This allows the Engine Module to calculate
true sequential fuel injection (SFI) mode of operation. If
the Engine Module detects an incorrect CMP signal while
the engine is running, DTC 53 will set. If the CMP signal is
lost while the engine is running, the fuel injection system
will shift to a calculated sequential fuel injection mode
based on the last fuel injection pulse, and the engine will
continue to nun. As long as the fault is present, the engine
can be restarted. It will run in the previously established
injection sequence.
