What’s going on guys, welcome back to our Channel! Today we have a 2015 Kia Optima and, as the title states, we have a problem with this car – a non-start problem. The code that I’m getting is P1B87, indicating a blown fuse for the Hybrid battery.
The symptoms of this issue include hearing one or two clicks when trying to start the car, instead of the typical three clicks. Additionally, the AV warning light may remain on, indicating a potential problem with the Hybrid battery. The specific part that’s causing the problem is a fuse switch located in the trunk.
To diagnose and fix this issue, I used an autel im608 for scanning the system and identified the faulty fuse. I tested the fuse using a multimeter and confirmed it was indeed the cause of the problem.
The replacement part needed is the PC300A fuse, upgraded to 150 amps as per the TSB. I demonstrated how to safely replace the fuse switch, which is crucial, especially when working with hybrid cars due to the high voltage involved.
After replacing the fuse switch and the battery, the car started up without any issues. I cleared the error codes and verified that the problem was successfully resolved.
