Introduced in 1998, the Kia Sedona is a minivan produced by Kia Motors. The Kia Sedona can develop electrical wiring problems that can negatively impact its operation.
If your Kia Sedona's CD player fails to properly accept or play CDs, a power supply fuse may be to blame. Locate the fuse box and check the diagram on the box cover for a fuse labelled "Stereo." Disconnect the fuse, wait at least 20 seconds for the player to reset and reconnect the fuse.
Anti-Theft Control Module
The Kia Sedona's antitheft control module receives a signal from the lock cylinder, which reads a chip in a Sedona ignition key. A bad antitheft control module may not accept this signal and immobilise, or disengage, the engine, resulting in difficulty starting the Sedona. Replace the antitheft control module to resolve the starting problems.
Stop Lamp Switch
The stop lamp switch in a Sedona, which signals the transmission to shift the car out of park when you press the brake, can malfunction due to improper positioning of the switch wiring harness. A misaligned harness can press against the steering column U-joint assembly, ultimately wearing away the harness's insulation. Inspect the harness for worn down insulation and replace it.
