Inspect the condition of unlocking through the mechanical key.

(a) Use mechanical key to repeat

lock and unlock actions,
meanwhile use multimeter to
measure voltage of BCM wire
harness connector IP50 terminal
No. 24.

Observe whether the voltage reading
of the multimeter is changed between
0V and 10V.

Inspect the left front door lock assembly.

(a) Refer to 11.7.7.1 Replacement of

Left Front Door Lock Assembly
to dismantle the left front door
lock assembly.

(b) Simulate unlock action by using

mechanical key. Use multimeter
to measure resistance between
left front door lock assembly
DR04 terminal No.8 and No.7.
