Technical Description
DTC C0369 indicates a circuit malfunction in the Transfer Case Control Module (TCCM) actuator motor or clutch coil circuit. The TCCM continuously monitors circuit continuity and current feedback through its internal driver stage (H-bridge/MOSFET). If open circuit, short-to-ground, or short-to-power is detected when commanding the actuator or during passive circuit diagnostic monitoring, C0369 is triggered and AWD/4WD engagement is inhibited.
Possible Causes
1. Skadat kablage eller korrosion i kontaktdon vid fördelningslådan/underredet p.g.a. fukt, vägsalt och värme.
2. Internt avbrott eller kortslutning i ställdonets motor/kopplingsspole i fördelningslådan.
3. Defekt drivsteg (H-brygga/MOSFET) eller intern hårdvaruskada i fördelningslådans styrdon (TCCM).

Mechanic's Tip
Before replacing expensive components, always double-check wiring and connections. 80% of all sensor faults are actually due to corroded contacts or broken wires.
