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 

Assembly and Vehicle Speed Sensor 

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.

Malfunction of the SRS-ECU

•

Malfunction of the combination meter

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 .
