Voltage Stabilizer (J532), Removing and Installing

Voltage Stabilizer (J532), Removing and Installing

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 (J532) is faulty:

If the voltage stabilizer (J532) is faulty, vehicle equipment such as the radio, the radio/RNS or the telephone will reset if the voltage supply is insufficient when the starter (B) 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 (J532). Currently, no entry is logged (in either the data bus on board diagnostic interface (J533) or the vehicle electrical system control module (J519) DTC memory) for a failed voltage stabilizer (J532) function. If the radio, the radio/RNS and the telephone all malfunction at the same time, first check the fuse for the voltage stabilizer (J532).

• Turn off the ignition and all electrical consumers.

• Remove the key.

Removing

- Remove the glove compartment.

- Remove the plastic nuts - arrows -, the voltage stabilizer (J532) - 3 - and the bracket - 1 -, paying attention to the wires that are still connected.






- Disconnect the connector - 2 -.

- Remove the voltage stabilizer (J532) - 3 - from the bracket - 1 -.

Installing

Install in reverse order of removal. Note the following:

- Tighten the plastic bolts to 1.5 Nm.
