Not so long ago I found in his car, Toyota Crown 1997 release complete with engine 2L-THE, still quite strange and not quite understandable at first sight damage. Previous history of this fault corny classic. Approximately as follows: "Everything was perfect, quiet travel on his typewriter is not a small one and a half years, no problems, but then yesterday it started. On the mound, and possibly even on a flat road (now and can not remember), suddenly on the dashboard lit lightbulb TRC, after a couple of seconds the machine stalled and went on. " An interesting problem, to say the word. Why? Yes, if only because the system TRC on this car with a diesel engine is different from the TRC system in a car with petrol unit, which has a dedicated servo control rod, located on the intake manifold. Here, internal standard, then there is no such, nor any of servo motors do not present any additional valve, just a standard intake manifold and an electronic fuel pump. Thrust is controlled entirely different way, through the electromagnetic relief valve "for mere words - through the valve" under pressure ". With the help define the diagnostic trouble codes, through contacts E1-Tc, which are right and just below the steering wheel on the round diagnostic connector. We discover that constantly "skips" codes 31-32-33-34 and 49. This means that out of order speed sensors or their chains and defective condition of the stop - the signals. With "stop" is understandable, not burned one of the bulbs, but here's the rest still quite interesting. From all this, there are not clear only one thing: how the ordinary fault can affect the way that the engine suddenly stalls when tidy lamp lights TRC? By the way, the performance speed sensors can be checked without removing them, and yes even in two ways. The first way is that you need from the cabin to get to the computer ABS, there will be written on the board which pins belong to the speed sensor. The second way - just the way to turn the wheel, first one way then the other, thereby providing access to the speed sensors and test them for performance, to check the rear speed sensor is not enough to push a lot of back seat and you will see sensor connector. How, in principle, one would expect, all the speed sensors are fully operable. As for the error code 49, replaced the bulb for the stop - signal and the code "left". But the cause of the problem was not discovered, the car still gloh once flew on the mound, the bulb lights tidy TRC and within seconds the car gloh. If the judge logically, we can assume that the light bulb between TRC and hillock there is some connection. I think you also think so and most likely we all think is correct. And here comes to mind, only one is the most common defect, which is called "aging". Over time, if not take care of their car, contacts have such a property as oxidized. I had been one such case with the Mitsubishi Diamante, which happened this strange thing: sometimes when reversing the car suddenly gloh, and sometimes without any problems. And the whole reason was that the mass of a strong oxidizing between engine and hull. That's the whole problem, Toyota Crown was "sick" the same. The same reason - a very strong oxidation of the masses, which stood almost in the air, just a few "hairs."
