Voltage stabilizer (J532)

Voltage stabilizer (J532)

The voltage stabilizer (J532) is installed inside the instrument panel behind the glove compartment. It stabilizes the voltage fluctuations in the vehicle electrical system to 12 volts, which are caused by the Stop/Start System.

This is what happens if the voltage stabilizer is faulty:

If the voltage stabilizer is faulty, vehicle equipment such as the radio, the radio/navigation system or the telephone will reset if the voltage supply is insufficient when the starter is operated. If the start/stop system for the above-mentioned electrical consumers reset each time the engine starts, then this indicates a defective voltage stabilizer. Currently there is no entry in the diagnosis interface or the vehicle electrical system control module DTC memory if the voltage stabilizer malfunctions. If the radio, the radio/navigation system and the telephone all malfunction at the same time, first check the fuse for the voltage stabilizer.
