Fault code 3106

Fault

Internal fault in the coordinator or the EDC
control unit.

Cause

The EDC control unit and the coordinator do
not agree about the relation between the
accelerator pedal and the idle speed switch.

Remarks

The fault results in 0% throttle actuation and
limp home speed of 750 rpm as long as the
fault is active.

Action

First check if there are any fault codes relating
to the accelerator pedal in the coordinator and
rectify these.

Then clear the fault code and test drive the
vehicle for approximately 10 minutes.

If the fault code has been regenerated, renew
the coordinator.

Clear the fault code again and test drive the
vehicle for approximately 10 minutes.

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

Fault code 3200

Fault

The control unit has received information that
the battery voltage has been above 47 V for
0.2 seconds.

Cause

The voltage between pin 1/6 and 2/7 in
connector B1 is too high.

Remarks

The engine will shut down immediately if the
battery voltage exceeds 47 V and the vehicle
speed = 0 km/h.

If the vehicle speed is > 0 km/h, the engine will
idle for 5 minutes before it is shut down.

The fault can occur when jump starting the
vehicle.

Action

Check the battery and alternator.

Check the connectors and wiring.

Fault code 3201

Fault

The control unit has received information that
the battery voltage has been below 9 V for
0.2 seconds.

Cause

The voltage between pin 1/6 and 2/7 in
connector B1 is too low.

Remarks

The fault may arise during cold starting if the
battery is in poor condition.

Action

Check the battery and alternator.

Check the connectors and wiring.

Fault code 3202

Fault

Internal fault in the control unit.

Cause

The control unit could not process (convert) the
battery voltage signal.

Remarks

A pre-programmed value is used (28 V) as long
as the fault is active.

Action

Erase the fault code. Test start the engine and
accelerate the engine to full speed.

Renew the control unit if the fault code is
regenerated.

Fault code 3203

Fault

The control unit does not rely on the battery
voltage signal even though it is within the
tolerances.

Cause

The battery voltage signal has been implausible
when compared to the normal values at certain
operating stages.

Remarks

Action

Check the battery and alternator.

Check the connectors and wiring.

Fault code 3204

Fault

The battery voltage has been within the range
of 30.56 V - 47,00 V for 5 seconds.

Cause

The voltage between pin 1/6 and 2/7 in
connector B1 is too high.

Remarks

The engine will start to idle if the battery
voltage has been between 30.56 V and 47.00 V
for 15 minutes.

Action

Check the battery and alternator.

Check the connectors and wiring.

Fault code 3205

Fault

The battery voltage has been within the range
of 9.00 V - 21.44 V for 5 seconds.

Cause

The voltage between pin 1/6 and 2/7 in
connector B1 is too low.

Remarks

The fault code will not be generated if the
engine speed is below 400 rpm to prevent
incorrect generation of fault codes when
starting.

Action

Check the battery and alternator.

Check the connectors and wiring.
