If a Bora 1.6L manual transmission cars, visiting more than 10,000 km, as a result of a major accident causing damage to the dashboard. Owners request an alternative control board assembly, have been replaced, though the emergence of anti-theft alarm lamp lit only immortal, after starting it only lasted 2s flame failure. However, before the replacement vehicle could start normally.
Volkswagen Bora sedan utilizes a third-generation anti-theft system, that is covered with combining instruments baked into anti-theft system control unit, a mix of anti-theft red light meter K117 (located on the instrument cluster speedometer), matching the multidiag engine control unit ignition coil switch on the identification and matching with D2 transmitting / transponder ignition key composition. Under normal circumstances, turn the ignition switch, electronic immobilizer anti-theft alarm light within the instrument cluster will illuminate after K117 3s off. When a failure occurs, such as following: the ignition key fit correctly; without sending / transponder in the ignition key; ignition key without authorization; engine control unit without authorization; identify faulty coil D2 or faulty data cable, etc., turn the ignition switch after, alarm system light will blink or stays on K117.
Analysis of vehicle faults that vehicles entering the security state, for the reason that no new instruments from the anti-theft system control unit caused by match. Having access to information, to find out if your new instruments are VDO production company, every once in awhile to complement the password, and enter a hard and fast code 13861. Data entered from the methods described on this fixed code, but nonetheless can not start. These units are portable not an authorized special maintenance station, people seriously isn't permitted an original data and also the corresponding technical support, so I can not know their own data entry error or even a wrong, so maintenance trouble.
Repeatedly thinking, considering that the original instrument is usually started, but not not commence a new instrument, which shows that the existing meter anti-theft system control unit isn't damaged. Unpack the original instrument to get a model for the 93C86 8-pin chip. At this point, I whim, can appear to be anti-theft solution because
Renault can clip V139 replacement chips? So after cutting each instruments inside the exchange of old chips. After refitted, still are not able to start. Apart again, but found that because of the negligence of the upper and lower legs welded obvious sign of backwards. At this time, I think it may come to naught beneath the chip will burn without doubt, however holding the dead horse a full time income horse medicine idea, your next chip re-welding, weld and refitted correctly, unexpectedly turned out to be capable to take up a. Simply by using a chip within the original instrument, the password is just not changed, will still be greater than 10,000 kilometers km. The employment of more(a) 12 months, this failure never occurs again.
With the above troubleshooting process, we can observe that for a similar situation just like the Passat B5, Audi A6 along with vehicles encountered and several in the sound with the antitheft device, we can by analogy, using the same technique to solve. Furthermore , it allows understanding of the author, from the repair process, encountered regarding the external environment just isn't allowed (eg no reasons for passwords, equipment and technical information, etc.), we need to use the experience accumulated in peacetime, broaden thinking solve the challenge. Some might appear impossible, but also by way of a thorough knowledge of the principles, boldly practice to ensure, and what happens if you receive unexpected results-
