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
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.

NO :
Go to Step 7.
STEP 7. Connector check: SRS-ECU connector
C-115 and junction block connector C-205
Q: Is the check result normal?
YES :
Check the harness wire for short circuit
between SRS-ECU connector C-115
(terminal No.16) and junction block
connector C-205 (terminal No.24), and
repair if necessary. Then go to Step 8.
