Voltage stabilizerJ532
Voltage stabilizer -J532-
The voltage stabilizer -J532- is located under the front passenger seat.
Its task is to stabilise the high voltage drop of the on-board power supply, resulting from the start-stop operation, to 12 volts.
If it becomes apparent that the electrical consumers (such as radio/navigation, telephone, dash panel insert) must be reset at each engine start, while operating the start-stop system, this indicates that the voltage stabilizer is defective.
If the above mentioned electrical consumers fail at the same time, first of all check the fuse of the voltage stabilizer see → Current flow diagrams, Electrical fault finding and Fitting locations.
A direct entry relating to a malfunction of the voltage stabilizer via → Vehicle diagnostic tester is not made at present.
Removing
–  Switch off the ignition and all electrical components.
–  Slide the front passenger seat as far forward as possible and lift it up (if possible).
–  Loosen the voltage stabilizer which is fastened to the floor covering with a velcro fastener from the seat backrest.
–  Disconnect the plug connection.
Install
Installation is carried out in the reverse order.
