GENERAL INFORMATION
This Trouble Code Sets if the Regulator has
detected an internal fault Can be caused by a
faulty Voltage Regulator Module
This Trouble Code Sets if the Regulator is near
the thermal shutdown point Can be caused by
excessive power consumption or insufficient
cooling air flow
This Trouble Code sets if the ECU Supply Voltage
is above 17.00V Can be based by faulty wiring,
faulty regulator or ECU / Connections
This Trouble Code sets if the ECU Supply Voltage
is below 10.00V Can be based by faulty wiring,
faulty regulator or ECU / Connections
This Trouble Code sets if the Critical Supply
Voltage is above 17.00V Can be based by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code sets if the Critical Supply
Voltage is below 10.00V Can be cbased by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code sets if the Chassis Supply
Voltage is above 18.00V Can be based by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code sets if the Chasssis Supply
Voltage is below 14.00V Can be based by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code sets if the Peak Injector Supply
Voltage is above 24.00V Can be based by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code sets if the Peak Injector Supply
Voltage is below 20.00V Can be based by faulty
wiring, faulty regulator or ECU / Connections
This Trouble Code Sets if the Throttle Release
Switch Signal is Open Circuit or Shorted to
Battery Voltage. Can be caused by Damaged
Wiring/Connections, a Faulty Throttle Safety
Switch or ECU
This Trouble Code Sets if the Throttle Safety
Switch Signal is Shorted to Ground. Can be
caused by Damaged Wiring/Connections, a
Faulty Throttle Safety Switch or ECU
This Trouble Code Sets if the Throttle Release
Switch Signal Indicates a Throttle Stuck Open.
Can be caused by a Stuck Throttle or
Misadjusted/Stuck Throttle Linkage.
This Trouble Code Sets if the Accessory Relay
Driver Circuit is Shorted to Voltage. Can be
caused by Damaged Wiring/Connections, a
Faulty Accessory Relay or ECU
This Trouble Code Sets if the Accessory Relay
Driver Circuit is Open. Can be caused by
Damaged Wiring/Connections, a Accessory
Ignition Relay or ECU
