Order of inspection
P0800 Transfer Case Control System (MIL Request) Medium
The P0800 code means the transfer case module on a 4x4 vehicle detected a fault and asked the engine computer to turn on the check engine light. The specific code is stored in the transfer case module, so you need a compatible scan tool. Until it is repaired, the four-wheel drive may not engage or may stay engaged.
