When the ignition is switched on (circuit
15), the engine control unit sends a start
enable request to the DAS [FBS] control unit.
If during this request circuit 15 is switched off
or interrupted before the DAS [FBS] control
unit could respond, the variable code sent the
first time is used again the next time circuit 15
is switched on, since the original request is
saved by the DAS [FBS] control.

Replace the DAS [FBS] control unit.

RISK OF EXPLOSION AND PO ISONING - AS05.30-Z-0001-01A
Do not open sodium-filled valves. Wear protectiv e gloves and safety glasses when handling damaged
valves.
Exhaust valves fill ed with sodium
Potential risks
Risk of explosion
Explosion may occur when melting down sodium-filled va lves. Sodium has a very low self-ignition temperature
(121 °C) and may spontaneously ignite in moist air.
Improper disposal may lead to fires due to moisture in scrap containers.
Risk of poisoning
The inhalation of toxic vapors causes severe irritation, shortness of breath, headaches, nausea and vomiting.
Risk of injury
Leaked sodium that comes into contact with moist body tissue (perspiration on hands, tears) may undergo a
severe, explosive reaction and generate heat. This may lead to skin ir ritation and burns, and to corneal damage
with possible blinding.
Safety instructions/precautions
Keep water and sources of heat and ignition away from sodium.
When handling damaged, sodium-filled valves, wear su itable protective gloves and safety glasses, if
necessary.
Never machine sodium-filled valves.
Do not open sodium-filled valves.
Observe all additional safety requireme nts and regulations in your country.
First aid measures
Skin and eye contact
Remove sodium, treat the injured area with an oily solution, e.g. Biseptol and consult a physician.
Risk of explosion and poisoning caused by the melting down
or improper handling of sodium-f illed valves. Risk of injury
caused by skin contact with s odium resulting in heat or
chemical burns.ENGINE 111, 112, 113,
