TROUBLESHOOTING

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-71

DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set if the voltage between the 
IG1 terminals (fuse No.2 circuit) and earth is lower 
than a predetermined value for a continuous period 
of 5 second or more. However, if the vehicle 
condition returns to normal, diagnosis code number 
41 will be automatically erased, and the SRS 
warning lamp will switch off.

PROBABLE CAUSES

•

Damaged wiring harnesses or connectors

•

Malfunction of the SRS-ECU

DIAGNOSIS PROCEDURE

STEP 1. Check junction block fuse number 2.

Q: Is the fuse burned out?

YES : 

Go to Step 4.

NO : 

Go to Step 2.

STEP 2. Measure the voltage at the SRS-ECU 
connector C-115.
(1) Disconnect the negative battery terminal.

(2) Disconnect SRS-ECU connector C-115.
(3) Connect the negative battery terminal.
(4) Turn the ignition switch to the "ON" position.

CAUTION

Do not insert a test probe into the terminal from 
its front side directly as the connector contact 
pressure may be weakened.
(5) Measure the voltage between C-115 harness 

side connector terminal 16 and body earth.

OK: 9 V or more.

Q: Is the check result normal?

YES : 

Erase the diagnosis code memory, and 

check the diagnosis code. If diagnosis code 
41 sets, replace the SRS-ECU (Refer to 

P.52B-178

). Then go to Step 8     .

NO : 

Go to Step 3.

STEP 3. Connector check: SRS-ECU connector 
C-115, ignition switch connector C-303, junction 
block connector C-203 and C-205

Q: Is the check result normal?

YES : 

Check the harness wire for open circuit 

between SRS-ECU connector C-115 
(terminal No.16) and the ignition switch 
connector C-303 (terminal No.2), and repair 
if necessary. Then go to Step 8.

NO : 

Repair or replace it. Then go to Step 8.

STEP 4. Check a burned-out fuse.
(1) Replace the fuse.
(2) Turn the ignition switch to the "ON" position, wait 

for at least one minute and then turn the ignition 
switch to the "LOCK" (OFF) position.

(3) Check the fuse.

Q: Is the fuse in good condition?

YES : 

Go to Step 8.

NO : 

Go to Step 5.

STEP 5. Measure the resistance at the junction 
block connector C-205.

(1) Disconnect junction block connector C-205, and 

measure at the wiring harness side.

CAUTION

Do not insert a test probe into the terminal from 
its front side directly as the connector contact 
pressure may be weakened.
(2) Measure the resistance between terminal 24 and 

body earth.

OK: Open circuit

Q: Is the check result normal?

YES : 

Check the other circuit, which flows through 

fuse number 2.

NO : 

Go to Step 6.
