Kia Cee'd: Fuses and Relays / Relay Box (Passenger Compartment) Description and operation. Kia Cee'd Service Manual / Body Electrical System / Fuses and Relays / Relay Box. Door Lock/Unlock Relay. The SJB receives commands from the BCM, operating the Door Lock/Unlock relay. A short door lock actuator is probably most well-known cause here. I have a 2007 KIA Sportage 2.7L V6 and it has lost all audible warnings including the front.
KIA CEE’D – CENTRAL LOCKING ISSUE FAULT:The central locking on a 2007 Kia Cee’d sometimes doesn’t work when using the remote control. We’ve replaced the battery in the remote control and checked all of the accessible electrical connectors but the problem persists. Have you heard of this problem? FIX:This model can suffer from a sticking ignition key warning switch located in the ignition switch. The central locking system won’t operate because it thinks the ignition key is still in the ignition switch.
Disconnect the vehicle battery and remove the steering column upper and lower shrouds. Disconnect the harness multi-plug from the ignition switch. Insert the key into the ignition switch, turn to ACC position (see Fig 2.1), then simultaneously press and hold the ignition switch locking pin (see Fig 2.2) and pull out the ignition switch barrel (see Fig 2.3).
Apply a light coating of a proprietary low temperature lithium soap grease to the ignition switch barrel and ignition key warning switch (see Fig 2.4) and this should correct the problem.
