DESCRIPTION
CAUSE
ACTION
P0563
DPS
system voltage
high
Rectifier failure, damaged
circuit wires or connection.
Measure battery voltage with
engine stopped. (Expected
value: 11 to 13 volts)
Measure battery voltage with
engine Running at 3500RPM.
(Expected value: 13 to 14.7 volts)
Check connections
on voltage regulator.
Check ground and positive
connections on battery.
P0563
ECM
System voltage
high
Damaged regulator.
An external battery charger
may have been used.
Measure battery voltage with
engine stopped. (Expected
value: 11 to 13 volts)
Measure battery voltage with
engine running. (Expected
value: 13 to 14.7 volts)
Check connections
on voltage regulator.
Check ground and positive
connections on battery.
Check ground on vehicle frame
P0601
DPS
CALIBRATION
FAULT
DPS not calibrated or
damage DPS
Try updating the DPS
P0601
SCM-XMR
Bad checksum
of Calibration
memory section
Lost of power on reflash
If an update file is available reflash
the SCM, if not clear the fault, if it
returns, replace the SCM.
P0615
ECM
Starter Relay
circuit open
Damaged relay,
Danaged start switch,
damaged circuit wires,
damaged connector,
damaged ECM pins.
Check start button, Check
Run/Stop button, check if free
weeling diode is in the good way.
Disconnect starter solenoid relay
Measure resistance from harness
connector: ECM-L3 to SS2
(Expected value: < 2 ohms)
Measure resistance from harness
connector: MG2-6 to SS1
(Expected value: < 2 ohms)
Measure resistance between
terminals SS1 and SS2. (Expected
value: 3 to 6 ohms)
P0616
ECM
Starter Relay
circuit shorted
to ground
Damaged relay,
Danaged start switch,
damaged circuit wires,
damaged connector,
damaged ECM pins.
Check start button, Check
Run/Stop button, check if free
weeling diode is in the good way.
Disconnect starter solenoid relay
Measure resistance from harness
connector: ECM-L3 to SS2
(Expected value: < 2 ohms)
Measure resistance from harness
connector: MG2-6 to SS1
(Expected value: < 2 ohms)
