* After correcting the condition, cycle the key switch
On-Off-On
The following test may help in determining the source of a
code:
NOTE: The EPS assembly is not serviceable and
must not be disassembled or EPS warranty will be
voided. Make sure to thoroughly troubleshoot the
entire system before replacing the EPS assembly.
Condition: Ignition Key Switch ON and NO EPS assist when
moving the steering wheel. Code flashing.
NOTE: Prior to troubleshooting below, make sure the
Ignition Key Switch has not been left on with the engine
not started. After five minutes, this will deactivate the EPS
and display the code. Turn the Ignition Key Switch OFF
and back to ON to reset and reactivate the EPS. If code
and symptom persists, continue as follows:
1. Check 30-amp EPS fuse.
2. Check EPS relay (may be switched with any other 4-pin
relay on PDM - replace relay if EPS normal after switch-
ing).
C1309 Temperature Above 120°
C
EPS internal 120° C over-temp condi-
tion has been detected
Clean the EPS housing and cooling fins. EPS will auto-recover when internal
temperature drops below 115° C
C1310 Vehicle Speed High
Vehicle speed signal received by the
EPS exceeds the maximum speed
specification
Intermittent main harness wires, defective
speed-sensor, or intermittent speed sen-
sor wires.
EPS will auto-recover when the
vehicle speed signal drops below
the maximum speed specification
C1311 Vehicle Speed Low
Vehicle speed signal received by the
EPS is zero or missing
Broken main harness wires, defective
speed-sensor, or broken speed sensor
wires.
EPS will auto-recover when the
vehicle speed signal returns to nor-
mal
C1312 Vehicle Speed Faulty
Vehicle speed CAN signal received by
the EPS incorrect or missing
Broken main harness CAN wires, defec-
tive speed-sensor, or broken speed sen-
sor wires.
EPS will auto-recover when the
vehicle speed signal returns to nor-
mal
C1313 Engine RPM High
Engine RPM signal received by the
EPS exceeds the maximum RPM
specification
Intermittent main harness RPM wires,
intermittent voltage regulator, intermittent
ACG stator wires.
EPS will auto-recover when engine
RPM signal drops below the maxi-
mum RPM specification
C1314 Engine RPM Low
Engine RPM signal received by the
EPS suddenly dropped below 500
RPM
Handlebar switch in the "OFF" position,
broken main harness RPM wires, defect
voltage regulator, broken ACG stator
wires.
EPS will auto-recover when engine
RPM signal returns to normal
C1315 Engine RPM Faulty
Engine RPM CAN signal received by
the EPS incorrect or missing
Broken main harness CAN wires or
defective ECM.
EPS will auto-recover when engine
RPM signal returns to normal
C1316 EEPROM Error
EPS internal memory error has been
detected
Internal EPS condition
Correct EPS condition*
C1317 CAN Bus Error
The EPS has lost CAN communica-
tion with the EFI ECM
Broken CAN wires in the main harness.
EFI ECM connector has been discon-
nected.
Correct EPS condition*
C1318 Internal CRC Error
EPS internal CRC calculation condi-
tion has been detected
EPS reflash has failed. Battery power
was lost, or the keyswitch was turned off,
during EPS reflash programming.
EPS must be reprogrammed
C1319 Boot Counter Exceeded
EPS internal application code condi-
tion has been detected
Intermittent power has prevented a suc-
cessful application code launch.
Correct EPS power condition*
C1320 Incorrect Vehicle
Speed-to-RPM Ratio
Vehicle speed signal received by the
EPS exceeds 10 MPH, but the engine
RPM signal less than 500 RPM
Intermittent or broken main harness RPM
wires, intermittent voltage regulator, inter-
mittent or broken ACG stator wires.
Correct EPS condition*
C1321 Vehicle Speed Erratic
Vehicle speed signal received by the
EPS changing at an unrealistic rate
Intermittent main harness, intermittent
speed sensor, dirty speed senor or trigger
wheel.
Correct EPS vehicle speed signal
condition*
C1322 Engine RPM Lost
Engine RPM signal received by the
EPS exceeds 500 RPM and then is
zero or missing
Handlebar switch in the "OFF" position,
broken main harness RPM wires, defect
voltage regulator, broken ACG stator
wires.
EPS will auto-recover when engine
RPM signal returns to normal
C1323 "EPS OFF" Gauge Dis-
play
Battery power has been applied to the
EPS for more than 5-minutes, but no
engine RPM signal has been
detected
The EPS has been automatically dis-
abled, after 5-minutes of inactivity, to con-
serve battery power.
EPS will auto-recover when engine
is started or the keyswitch is cycled
On-Off-On
C1324 Loss of CAN communica-
tion with EPS unit
The gauge has lost CAN communica-
tion with the EPS
Broken CAN wires in the main harness or
disconnected EPS. This is not an EPS
generated DTC; gauge DTC display only.
Gauge DTC display will clear when
the EPS-to-gauge CAN communica-
tion is restored.
C1325 Dual Loss
EPS loss of both the vehicle speed
and the engine RPM signals has been
detected
Handlebar switch in the "OFF" position,
the engine stalled (keyswitch "ON"), bro-
ken harness wires, loss of CAN data sig-
nal.
EPS will auto-recover when either
the vehicle speed or engine RPM
signal is restored.
C1326 Rotor Position Encoder
EPS internal rotor position encoder
variance condition has been detected
Internal EPS Condition
Correct EPS condition*
C1327 Voltage Converter Error
(Low)
EPS internal voltage converter
low-voltage condition has been
detected
