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 7 and
body earth.
OK: Open circuit
Q: Is the check result normal?
YES :
Check the other circuit, which flows through
fuse number 3.
NO :
Go to Step 6.

STEP 6. Measure the resistance at the SRS-ECU
connector C-115.
(1) Disconnect SRS-ECU connector C-115, 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 13 and
body earth.
OK: Open circuit
Q: Is the check result normal?
YES :
Erase the diagnosis code memory, and
check the diagnosis code. If diagnosis code
42 sets, replace the SRS-ECU. (Refer to
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.13) and junction block
connector C-205 (terminal No.7), and repair
if necessary. Then go to Step 8.
NO :
Repair or replace it. Then go to Step 8.

STEP 8. Check whether the diagnosis code is
reset.
Q: Is diagnosis code 42 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
).
Code No.43: SRS warning lamp circuit open-circuited (Lamp does not Illuminate).
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 an open circuit is
detected for a continuous period of 5 seconds while
the SRS-ECU is monitoring the SRS warning lamp
and the lamp is OFF (transistor OFF). 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 combination meter
DIAGNOSIS PROCEDURE
STEP 1. Check the SRS warning lamp.
(1) Disconnect the negative battery terminal.
(2) Disconnected the SRS-ECU connector C-115.
(3) Connect the negative battery terminal.
(4) Turn the ignition switch to the "ON" position.
Q: Does the warning lamp illuminate?
YES :
Erase the diagnosis code memory, and
check the diagnosis code. If diagnosis code
43 sets, replace the SRS-ECU (Refer to
NO :
Go to Step 2.
STEP 2. Measure the resistance at the SRS-ECU
connector C-115.
(1) Disconnect the negative battery terminal.
(2) Disconnected the 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 resistance between C-115 harness
side connector terminal 7 and earth.
OK: Less than 2
Ω
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Go to Step 4.
