Installation recommendations
– Before removing the original unit, always disconnect the vehicle battery (negative pole) and wait a few minutes to discharge the residual charges in the system.
– Work in a dry, clean environment and prevent moisture, dust or oil from entering the fuse box and connectors.
– When disconnecting the connectors, do not use brute force – release the fuses/locks first and only then pull out the connectors. Damage to pins or plastic locks can cause poor contact and subsequent electrical malfunctions.
– Before installing the new BSM R09 DELPHI unit, check the condition of the contacts in the vehicle wiring connectors (corroded or heated pins should be repaired or replaced).
– Place the unit firmly in the holders so that the cabling is not in tension and that it cannot come loose while driving. Even if one of the smaller mounts is damaged, the main mount must be fully functional.
– After reconnecting the battery, check the function of the main electrical circuits (lights, cooling fan, wipers, fuel pump, etc.).
– For modern cars, after replacing the unit, it is advisable to carry out a diagnosis using a diagnostic device, to erase any old errors and to verify the correct communication of the units in the vehicle network.
This part is a suitable choice for professional workshops and experienced home repairers who need a reliable R09 DELPHI BSM unit for Citroën and Peugeot with product number 9667199780 and related codes 6500HV and 6500HW.
