airbag reset tool
control unit is not able to talk to the decoder, the anti-theft system and Abs are unable to talk to the decoder.
Fault diagnosis: the vehicle because the motor exhaust black smoke to fix, though the fault code read because of the car vital programmer
decoder, observed it difficult to communicate along with the motor regulate device, then the decoder with Abdominal muscles and anti-theft devices for communication, found that each can not connect. And Abs fault mild stays lit.
Voltage measuring the fault prognosis seat just about every foot: 16 toes (optimistic electricity offer) 12V, four feet (electric power detrimental) 0V, seven toes (facts communication traces) 57V. Within the measurement final results position of perspective,ECU programmer
the lower voltage of seven toes, beneath normal circumstances need to about 12V, discover the first automobile circuit diagram investigation observed 3 management device diagnosis, Block 7 ft interlinked. Are J104 (Ab muscles control device), J234 (airbag control unit) and J362 (anti-theft manage unit), the three control units information interaction line linked to collectively, and afterwards connected to the No. 7 pin on the fault prognosis socket, is suspected the hurt into the manage device in a single on the three management units. Disassemble the motive force aspect in the cab guard, discover the anti-theft control device.
Measurement info with the above point of check out, there exists no discovery, communication line voltage continues to be small, unplug the anti-theft manage device, measuring the voltage of your details line continues to be nine. 57V and decoder or unable to talk to Ab muscles Description can't talk failure is not really caused owing into the immobilizer manage unit.
When the Stomach muscles handle device is usually taken off, after which you can the decoder interaction examination, the anti-theft device can talk to the engine manage unit can connect, the above mentioned detection Description inside problems of the Abs handle unit. auto diagnostic tools
Time you measure the voltage about the data line to become twelve.3V, has actually been restored to standard.
