Instrument ignition swap failure prompted Audi brake pedal

Symptom: Audi A4L vehicle in ordinary driving , the situation will prompt retarding the ignition change when the meter malfunction , this phenomenon is multi-cardiag m8 specifically apparent once the uneven roads and every time occurs in the event the brake pedal . Shoppers have the 2nd repair service this fault.

Troubleshooting : Use VAS5054 question fault code , which 01 - Engine electronics stores fault code 5464 P2535 00, its that means could be the ignition / starter change circuit limited circuit to favourable ( occasional ) ; 46 - consolation program with all the ATA central module (J393) stored fault codes 03305006 , that means the engine begin request wire brief circuit to positive ( sporadic ).

When J393 right after recording a fault code 03305006 will likely be prompted to defective ignition swap during the instrument cluster , and if this failure persists , the motor will not likely start out. Should the sign line 50 comfort system central module (J393) and B42 engine manage unit autel maxidas ds708 review connector about the take a look at box in between limited circuit to constructive , will the failure phenomenon. Then query ELSA WI N, analysis on the job with the sign strains from the technique . Conclusion : the sign line separate with the motor manage device connected to the wire (J 623) to J393, identified for engine commencing , the suggestions signal to J393.

In the obvious once the higher than basic principle , so that you can simulate the failure phenomenon , the very first sign line along with the 30th line jumper , the instrument promptly alarm and J623 and J393 are recorded and prior to the identical fault code. This can be due to the fact it could possibly determine the sign line launch creader scanner short circuit to beneficial customer sparked Symptom described . Up coming, locate the place of failure, one particular investigation after the open aspect sill trim across the correct aspect and trunk interior panels , and eventually identified a metallic clip over the footrest to two traces frayed . Confirmed by measurement of which a person conclusion may be the fifty signal strains , coincidentally, is simply an additional one particular wire brake swap sign line , which clarifies why only when the brake pedal instrument will prompt the ignition switch failure.
