SRS Warning Light Circuit Malfunction (Always lights up, when
ignition switch is in LOCK position.)
CIRCUIT DESCRIPTION
The SRS warning light is located on the combination meter.
When the SRS is normal, the SRS warning light lights up for approx. 6 seconds after the ignition switch is
turned from the LOCK position to ACC or ON position, and then turns off automatically.
If there is a malfunction in the SRS, the SRS warning light lights up to inform the driver of the abnormality.
When terminals Tc and E1 of the DLC1 are connected, the DTC is displayed by blinking the SRS warning
light.

INSPECTION PROCEDURE
1 Check DOME fuse.
PREPARATION:
Remove DOME fuse from engine room junction block.
CHECK:
Check continuity of DOME fuse.
OK:
Below 1.0 W or continuity
NG Check for short in all the harness and compo-
nents connected to DOME fuse.
(See attached wiring diagram.)
OK
2 Check voltage between terminals +B and E of wireless door lock ECU connector.
PREPARATION:
Remove the wireless door lock ECU from No.1 instrument pan-
el brace.
CHECK:
Measure voltage between terminals +B and GND of wireless
door lock ECU.
OK:
Voltage: 10 ± 14 V
OK Proceed to next circuit inspection shown on
problem symptoms table (See page DI±809).

Door Unlock Detection Switch Circuit
CIRCUIT DESCRIPTION
The door unlock detection switch is built into the door lock motor assembly. The switch is OFF when the
door lock knob is in Lock position, and is ON When the Knob is in Unlock position.
Furthermore, the door unlock detection switch circuit has terminal +B connected inside the theft deterrent
ECU, when the door unlock detection switch is OFF, battery positive voltage is applied to the terminal of the
door unlock detection switch circuit of the wireless door lock ECU.

Door Key Lock and Unlock Switch Circuit (Unlock Side)
CIRCUIT DESCRIPTION
The Key±operated switch is built into the door key cylinder. When the key is turned to the lock side, the lock
terminal of the switch is grounded, and when the key is turned to the unlock side the unlock terminal is
grounded.
Furthermore, the door key lock and unlock switch circuit has terminal +B connected inside the theft deterrent
ECU, when neither the lock nor unlock terminal of the key lock and unlock switch are grounded, battery posi-
tive voltage is applied to the door key lock and unlock switch circuit of the wireless door lock ECU.
( Tr inside the ECU coming ON causes the wireless door lock ECU to output a signal to unlock all the doors.)
