NOTE: After inspecting intermediate connectors
C-05, C-04, C-205 and C-203 inspect the wiring
harness. If intermediate connectors C-05, C-04,
C-205 and C-203 are damaged, repair or replace
them. Then go to Step 5 .

Q: Is the check result normal?

YES :

Replace the combination meter (Refer to

GROUP 54A

−

Combination Meters

P.54A-72

). Then go to Step 5 .

NO :

Repair the harness wires between
SRS-ECU connector C-115 (terminal No.8)
and the ignition switch connector C-303
(terminal No.2). Then go to Step 5.

STEP 4. Connector check: SRS-ECU connector
C-115 and earth

Q: Is the check result normal?

YES :

Repair the harness wires between

SRS-ECU connector C-115 (terminal No.7)
and earth. Then go to Step 5.

NO :

Repair or replace it. Then go to Step 5.

STEP 5. Check whether the diagnosis code is
reset.

Q: Is diagnosis code 43 set?

YES :

Return to Step 1.

NO :

The procedure is complete (If no
malfunctions are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00

−

How to Use

Troubleshooting/Inspection Service Points

P.00-6

).

Code No.43: SRS warning lamp circuit open-circuited (Lamp does not Switch Off).

OPERATION

•

Power for the SRS warning lamp is supplied from
the ignition switch (IG1).

•

The SRS warning lamp illuminates when the
ignition switch is turned to the "ON" position and
goes out after approximately 7 seconds if there is
not a malfunction in the SRS system.

DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when a short to earth
occurs in the harness between the SRS warning
lamp and SRS-ECU while SRS-ECU is monitoring
the lamp and the lamp is ON. However, if the vehicle
condition returns to normal, diagnosis code 43 will be
automatically erased, and the SRS warning lamp will
go out.

DIAGNOSIS PROCEDURE

STEP 1. Connector check: SRS-ECU connector
C-115

(1) Disconnect SRS-ECU connectors C-115.

(2) Check the short spring for the warning lamp

inside the harness side connector for improper
contact or deformation.

Q: Is the check result normal.

YES :

Then go to Step 2.

NO :

Repair or replace the SRS-ECU connector
C-115. Then go to Step 4.

STEP 2. Check the SRS warning lamp.
(1) Disconnect the negative battery cable.

(2) Disconnect the combination meter connector

C-05.

(3) Connect the negative battery cable.
(4) Turn the ignition switch to the "ON" position.

Q: Does the SRS warning lamp go out?

YES :

Go to Step 3.

NO :

Replace the combination meter (Refer to
GROUP 54A

−

Combination Meters

Assembly and Vehicle Speed Sensor

P.54A-72

). Then go to Step 4 .
