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 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is no longer active as soon as the emergency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.
