Modern braking systems in trucks and buses consist of more than just pneumatic or hydraulic actuators. The ABS/ESP Control Unit makes use of multiple variables before it operates the brake calipers and Electronic Throttle Body (ETB). As long as trouble stays out, it really is a great piece of engineering.
But operating under the same conditions as an Engine Control Unit, the ABS/ESP Control Unit unfortunately also has a substantial failure rate. Temperature, engine vibrations and water are real threats for the delicate electronics. The current use of ceramics and embedded systems may have elevated the computing power and reduced weight and volume, but the minuscule hybrid connections are extremely vulnerable. Exposed bare dies are mostly covered with silicone gel, but even that doesn’t always protect them properly.
The complexity of the ABS/ESP Control Unit makes replacing rather expensive, therefore remanufacturing is a viable option. However, the combination of embedded systems, hybrid connections and sensitive parts complicates the remanufacturing process. Alec GmbH uses advanced machinery, such as the wire bonding machine in order to renew all hybrid wire connections. This guarantees the same or higher quality as an OEM ABS/ESP Control Unit.
