Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Door Lock System
The system has a pair of circuits between door lock actuators and the MICU to improve safety of the system. One is for driver's side door lock actuators, and another is for front passenger's side door lock actuators. Each circuit has two fuses, and even if one of the fuses is blown, at least the driver's side, or the front passenger's side actuators continue to work normally. When one fuse is blown, another fuse in the same circuit must be checked (for example, when the under-dash fuse/relay box No. 35 fuse is blown, the No. 49 fuse also must be checked).
