BODY ELECTRICAL SYSTEM – THEFT DETERRENT AND DOOR LOCK CONTROL SYSTEM

INSPECTION PROCEDURES

1   Check POWER M–fuse.

R/B No.2

POWER M-Fuse
N09001

P   Remove POWER M fuse from R/B No. 2

C   Check continuity of POWER M–fuse.

OK   Continuity

OK

NG   Check for short in all the harness and components connected to the DOOR fusible link (See attached wiring diagram). *1

2   Check voltage between terminals +B2 of ECU connector and body ground.

LOCK

+B2
BE3843
N12009

P   (1)  Remove the instrument panel.
           See BO section.
     (2)  Disconnect the ECU connector.

C   Measure voltage between terminals +B2 of ECU connector and body ground.

OK   Voltage: 10 – 14 V

NG

OK   Proceed to next circuit inspection shown on matrix chart (See page BE–123).

Check and repair harness and connectors between ECU and battery (See page IN–30).

*1:  The power source is supplied to the actuator (door lock motor, through the theft deterrent and door lock ECU. Accordingly, if a short circuit of the W/H or actuator occurs in the actuator circuit the POWER M–Fuse may become OPEN, so also inspect the actuator (door lock motor circuit on page BE–154).
