Check the Oxygen Sensor wiring and the operation of the sensor. The value should fluctuate between 0.02 and 0.85V. Slow fluctuation indicates a polluted Oxygen sensor and negative values indicate a damaged sensor.

U3 SRS Fault Codes - System 3. 3 Seatbelt Tensioning System Firing Circuit - Driver Side Disconnect plug connection between seat wiring. BMW Airbag Diagnostic. The airbag lamps on all three of my E36 BMWs have been on at one time. Sometimes the light will stay lit, and then go out after about 3 minutes of driving. Recover my files 3.98 serial no. SRS and did a scan and came up with a 02 04 code Firing circuit, driver airbag.

Possible causes: Fuel tank ran empty, Incorrect Fuel Pressure, Injector valve defective or coked, Engine Temperature Sensor defective, Secondary air leak, Fuel evaporation control system defective, Air Flow Meter defective and/or the combustion is being disturbed by mechanical failure (Spark plugs,, compression, intake/exhaust valves.etc.) 1 2 1 5 A i r M a s s / V o l u m e S e n s o r T h i s c o d e i s s t o r e d i f t h e r e i s a b r e a k o r s h o r t - c i r c u i t a t: A i r Mass Flow Meter or its supply wires or the voltage supply to Air Mass Flow Meter insufficient. Cable damage is the most common cause of this trouble code. 1 2 1 6 T h r o t t l e P o t e n t i o m e t e r T h i s c o d e i s s t o r e d i f a b r e a k o r s h o r t - c i r c u i t o c c u r s i n t h e wiring to the Throttle Potentiometer or the potentiometer is defective. Damage at the throttle potentiometer connection is the most common cause of this fault.

Generally this code occurs with other defects. Causes may be a faulty Idle Speed Actuator, Injector Valves, Ig nition Coil on P lug, Oxygen Sensor Heating Relay, Fuel Evaporation, Control Valve, Malfunction Indicator Lamp (MIL) and/or EKP Relay. Delete the code after examining for other faults. If the code recurs, delete code, then disconnect the DME for a minimum of 5 minutes to initiate a reset. If code recurs and no other defects are found the DME is most likely damaged and must be replaced.
