Diagnostic steps:

Notes:

When there is no remote control key, use the special setting function of fault diagnosis tester to
drive the central control door locks. Select in sequence: the body control module/BCM special set
function/lock, unlock double-lock (all doors)/lock all doors.

1

Inspect locking through the remote control key.

Confirm whether triggering to lock by the remote control key.

2

Inspect the possible fault of the remote control anti-theft system.

A. Inspect and repair the remote anti-theft system for potential malfunction.

Confirm whether the electric door lock is working correctly.

Yes

3

Inspect the condition of locking through mechanical key or central control button.

(a) Use mechanical key or central control button on left front glass lifter switch to repeat lock

and unlock actions, meanwhile use multimeter to measure voltage of BCM wire harness
connector IP50 terminal No. 4.

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

4

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 lock action by
mechanical key, measure
resistance valure between left
front door lock assemblyDR04的
terminal No.9 and No.7 by
millimeter

Standard resistant value :is less than
1Ω

Confirm if the resistance conforms to
standard value.

Inspect the fastener switch.

(a) Dismantle central control door

lock button.

(b) Press central control door lock

button to carry out lock action,
meanwhile use multimeter to
measure resistance between wire
harness connector IP29 terminal
No.5 and No.4 of lock switch.

Standard resistant value :is less than
1Ω

Confirm if the resistance conforms to
standard value.

Replace the lock switch.

(a) Replace center control lock button , Refer to11.7.7.4 lock switch replacement .

Lock by a central door lock button to confirm whether the electric door lock normally locks.

8

Inspect the circuit between the BCM wire harness connector IP49 and the left front door
motor assembly wire harness connector DR04.

(a) For dismantling of BCM wire

harness connector, refer to
11.8.8.1 Replacement of BCM.

(b) Dismantle left frnt door lock

motor assembly wire harness
terminal. Refer to 11.7.7.1
Replacement of left front door
lock assembly.

(c) Use multimeter to measure

resistance between BCM wire
harness connector IP49 terminal
No. 16 and left front door motor
assembly wire harness connector
DR04 terminal No. 9.
