Fault code E003

Fault

Internal fault in the control unit.

Cause

The control unit measures the engine speed on 
engine speed sensor 1 incorrectly due to an 
internal fault in the control unit.

Remarks

The fuel injection (the engine) is switched off 
as long as the fault is active.

As a result, the fault may also generate other 
fault codes.

Action

Clear the fault code and drive the vehicle for 
approximately 10 minutes. Check if the fault 
code has been generated again.

If the fault code has been regenerated, renew 
the control unit.

Fault code E004

Fault

Internal fault in the control unit.

Cause

The control unit measures the engine speed on 
engine speed sensor 2 incorrectly due to an 
internal fault in the control unit.

Remarks

The fuel injection (the engine) is switched off 
as long as the fault is active.

As a result, the fault may also generate other 
fault codes.

Action

Clear the fault code and drive the vehicle for 
approximately 10 minutes. Check if the fault 
code has been generated again.

If the fault code has been regenerated, renew 
the control unit.

Fault code E005

Fault

Internal fault in the control unit.

Cause

Remarks

The fuel injection (the engine) is switched off 
as long as the fault is active.

As a result, the fault may also generate other 
fault codes.

Action

Clear the fault code and drive the vehicle for 
approximately 10 minutes. Check if the fault 
code has been generated again.

If the fault code has been regenerated, renew 
the control unit.

Fault code E006

Fault

Internal fault in the control unit.

Cause

Remarks

The fuel injection (the engine) is switched off 
as long as the fault is active.

As a result, the fault may also generate other 
fault codes.

Action

Clear the fault code and drive the vehicle for 
approximately 10 minutes. Check if the fault 
code has been generated again.

If the fault code has been regenerated, renew 
the control unit.

Fault code E200

Fault

The fault code is generated when the coolant 
temperature is above 104°C.

Cause

For some reason, the coolant temperature has 
become too high.

Remarks

When the coolant temperature is above 104°C, 
the maximum engine torque is limited to 
prevent the engine from overheating. Engine 
power is gradually reduced, with a maximum 
reduction of 30% at 106°C.

Action

Ensure that the engine cooling system is 
functioning correctly.

Fault code E300

Fault

The program in the control unit has been 
altered in a prohibited manner.

Cause

The program in the control unit has been 
altered in a prohibited manner, e.g. by using a 
programming tool not approved by Scania.

Remarks

The fault results in 0% throttle actuation and 
engine speed drops to idle speed.

Action

Renew the control unit.

Fault code FFFD

Fault

Signal from the emergency shutdown switch.

Cause

A CAN message from the coordinator indicates 
that the emergency shutdown switch, which is 
connected to the coordinator, is activated.

Remarks

If the vehicle is stationary, the engine is 
switched off.

If the vehicle is moving, the engine will begin 
to idle. This allows the use of power steering 
etc.

It is not possible to use the cruise control.

The fault code is generated every time the 
emergency shutdown switch is used. The fault 
is no longer active as soon as the emergency 
shutdown switch is reset.

Action

Check the switch, connectors and wiring.

Fault code FFFE

Fault

There are fault codes in the coordinator.

Cause

There are one or more fault codes in the 
coordinator that have affected the function of 
the engine.

Remarks

The fault code is generated if there are fault 
codes in the coordinator which affect the 
function of the engine.

Action

If the fault code is active, check the fault codes 
in the coordinator.
