Electronics-HU: The dark side of progress
Airbag and electronically controlled exhaust gas purification to ensure children develop the TUV auditors SONY BP-65H Battery. Especially with vehicles that are older than three years, the error rate increases dramatically.
Problems with electronic systems are emerging especially in airbags, ESP and environmental instrumentation. And the shortcomings quotas to increase as older vehicles are. Now this, although, only the first results of an investigation of the TUV Süd in Munich. But is “the tendency” to be confirmed with the increasing number of investigations, said spokesperson Frank TÜV-South people.
The main electronic investigation (electronic HU) is mandatory since April, and for many car owners SONY BP-90 Battery had brought them surprises – because failure to control units, the abatement or about the airbag going strong into the money. “For example, an airbag must be replaced, come quickly from 1000 to 1500 € together,” reckons people.
Given such costs, it is highly tempting for some car owners, rather disconnected the warning light for the airbag control, as so to dig deep into their pockets. In the previous Prüfprozedere was such a thing to spot. But apart from such manipulations, the experts fear that they know for the time being only the tip of the iceberg.
While were in the mid-TÜV only 81 seats in well 145 000 vehicles examined in the second quarter of this year, defective, however; may quickly on this component have serious consequences. can also shocking that this figure was reached in vehicles that were not older than three years – and a proposal TÜV-South CEO Horst Schneider Alert: “It is unacceptable that the air bag even in a relatively new vehicle does not function reliably. »
Even before the introduction of advanced electronic HU the experts had found by TÜV Süd more than 13,000 defective air bags in the 2008 general inspections. Schneider: “Thanks to new technology, we now find more errors, manipulations or, for example after an accident, not again mounted components.” That shows the high number of defective air bags that had been found in older cars. In the four-year olds, the number doubled to 161, where the seven and eight year old vehicles are driven up even without a functioning air bag 525. For the nine-year-old cars were once about 200 added.
Further anomalies are for vehicles that drove up the first time since April to HU, the ESP as well as error in engine management in relation to emission control systems. The remarkable figure: 245 times has failed, according to TÜV-analysis of the engine management system for the cleaning of exhaust gases from three year old vehicles, which can increase sharply in the rule of pollutant emissions – and in this area take the deficiencies figures as well, the older the vehicles are.
444 times the failed engine management systems in terms of emissions in the seven and eight year old car BP-GL65 Battery. Given these figures calls Schneider: “It must be ensured, given that the security level of a vehicle leaving the factory gate for the life remains.”
The advanced electronics HU is the case for all three years old vehicles that need first to HU. Studied are first installed, authenticity and operation of eight safety: braking, steering, active light devices such as light curve, seat belts or other restraint systems, airbags, speed, dynamic handling control systems such as ESP and convertibles and the rollover protection.
On the basis of the collected data of the different types of vehicles are targeted at the various systems tested parts of the chain of action with specific algorithms. This means, for example, the electronic parking brake that can be driven on the brake tester scan modes, in which the gradual effect of the brake is checked.
In ABS, the experts look first to determine whether all sensors are properly installed, whether they conform to the requirements of the manufacturer and if they are not damaged. Then, through various steps of the self out again checked on the basis of the collected data type specific functionality. The same procedure applies to air bags. Added another check of the sensors depends on the manufacturer’s specified places in the vehicle. In addition, the experts take a close look at whether the airbags not affected by additions or BP-GL95 Battery even can be dangerous.
This seems to be necessary. “Some drivers screw the mic for the speakerphone on the airbag on the A-pillar. If the trigger properly in an accident, ends up the mic, including the head of the screw driver, “Horst Schneider describes his experience examiner.
