DOOR LOCK TIMER UNIT INSPECTION

BME091467830202

## With Double Locking System

1. Remove the right side lower panel.

2. Measure the voltage at the door lock timer unit terminals as indicated below.

3. Disconnect the door lock timer unit connector before inspecting for continuity at terminals K, L, M, and N.

  • If not as specified, inspect the parts listed under "Action."
  • If the parts and wiring harnesses are okay but the system still does not work properly, replace the door lock timer unit.
