DTC P0641, P0651
DESCRIPTION AND OPERATION
. The ECM controls 5V power from terminal
50 for sensor power-1 and terminal 68 for sensor power-2. The
ECM provides a common ground point for components through
terminal 61 for sensor power-1 and terminal 62 for sensor
power-2. The ECM monitors voltage on the 5V reference cir-
cuits and sets the DTCs below if the voltage goes out of range.
Refer to
•
DTC P0641 is displayed when sensor voltage 1 is out of
range. The 5V sensor power-1 circuit supplies the TCA,
VSS, jiffy stand sensor and sensor 2 of the TGS with a 5V
reference signal.
•
DTC P0651 is displayed when sensor power-2 is out of
range. The 5V sensor power-2 circuit supplies the TMAP
sensor and sensor 1 of the TGS with a 5V reference signal.

DTC P1001, P1002, P1003, P1004
DESCRIPTION AND OPERATION
With IGN ON and the engine stop switch at RUN, the ECM will
energize the system relay to complete the circuit to the in-tank
fuel pump, ignition coils and fuel injectors. They will remain
powered as long as the engine is cranking or running, and the
ECM is receiving ignition reference pulses from the CKP
sensor. If there are no reference pulses, the ECM will de-
energize the system relay within 2 seconds after ignition is ON
or engine has stalled, or immediately after the ignition is shut
OFF.

Within the ECM, there are two independent Analog/Digital (A/D)
converter modules used to validate the input of Twist Grip
Sensor 2 (TGS2). TGS2 inputs are sent into both converter
modules and if the output of the two readings are not within
the designated value of each other, for a specified time, then
DTC P1270 fault is initiated.
Unless the ECM has a poor or intermittent connection, DTC
P1270 indicates the ECM is defective and requires replace-
ment. See the service manual for replacement information.
NOTE
After replacing the ECM, perform password learning procedure
and clear codes.

DTC P1351, P1352, P1354, P1355
DESCRIPTION AND OPERATION
Ignition coil DTCs will set if the ignition coil primary voltage is
out of range. This could occur if there is an open coil or loss
of power to the coil. If front and rear DTCs are set simultan-
eously, it is likely a coil power failure or a coil failure.
The coil receives power from the system relay at the same
time that the fuel pump and injectors are activated. The system
relay is active for the first 2 seconds after the ignition switch is
turned ON and then shuts off until rpm is detected from the
CKP sensor, at which time system relay is reactivated. The
ECM is responsible for turning on the system relay by providing
the ground to activate the relay, which in turn powers the coil.
