The ECM does not detect vehicle speed when conditions indicate vehicle speed should be present. This diagnostic code will not occur if programmed to 3000 rpm and desird engine pm is greater than VSL Protection.

VSL Protection is less than 3000 rpm, and vehicle speed is constant when engine parameters indicate it should be changing.

Indicates the Coolant Temperature is above 221°F (105°C) on 3116 engines and 224°F (107°C) on 3216 engines. Engine Monitoring must be programmed to WARNING or DERATE before this diagnostic code can occur. NOTE: This diagnostic code represents an event and not an Electronic System fault.

Indicates the coolant Tempeature is above 226°F (106°C) on 3116 and 230°F (110°C) on 3126 engines. Engine Monitoring must be progammed to WARNING o DERATE before this diagnostic can occur. NOTE: This diagnostic code represents an event and not an Electornic System fault.

The Boost Pressure signal voltage is above acceptable range.

The supply voltage for all engine sensors (except Speed/Timing and Throttle Position) is below normal level.

The “Truck Manufacturer Parameter” has not been programmed. The parameter must be programmed for the manufacturer of the chassis in order to configure the correct options and ranges for the engine.

Note: The “Truck Manufacturer Parameter” must be programmed before the “Customer Parameters” are programmed.

Probable Causes:

1) ECM not programmed correctly

The Engine Control Module (ECM) detects one of the following items after attempting to operate the injector:

•A low current condition (open circuit) exists in the wiring for the cylinder injector solenoid.
•A high current condition (short circuit) exists in the injector solenoid.

Probable Causes:

1) ECM Connection/Harness
2) Cylinder injector failure
3) Injector solenoid failure
4) Harness from ECM to valve cover connector
5) ECM failure
6) Injector harness under valve cover

The idle timer has expired to stop the engine. NOTE: This diagnostic code represents an event and not an Electronic System fault.
