(5)
caution |
Do not insert a test probe
into the terminal from its front side directly
as the connector
contact pressure may be weakened.
|
Voltage measurement between C-147 harness side
connector terminal 16 and body earth. OK: 9 V
or more.
Q.
Is the check result normal?
Erase the
diagnosis code memory, and check the diagnosis code. If
diagnosis code
41 sets, replace the SRS-ECU (Refer to ). Then go
to Step
7.
Go to Step
3.

Q.
Is the check result normal?
Check the
harness wires for open circuit between SRS-ECU connector
C-147 (terminal
No.16) and ignition switch connector C-307 (terminal No.2),
and repair if necessary. Then go
to Step 7.
Repair or
replace it. Then go to Step 7.
|
|
(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.

|
(2)
caution |
Do not insert a test probe
into the terminal from its front side directly
as the connector
contact pressure may be weakened.
|
Resistance measurement between terminal 24 and body
earth. OK: Open circuit
Q.
Is the check result normal?
Check the other
circuit, which flows through fuse number 2.
Go to Step
6.
|

|
(1)Disconnect SRS-ECU connector
C-147, and measure at the wiring harness side.

(2)
caution |
Do not insert a test probe
into the terminal from its front side directly
as the connector
contact pressure may be weakened.
|
Resistance measurement between terminal 16 and body
earth. OK: Open circuit
Q.
Is the check result normal?
Go to Step
7.
Check the
harness wire for short circuit between SRS-ECU connector
C-147 (terminal
No.16) and junction block connector C-205 (terminal No.24),
and repair if necessary.

|
Q.
Is diagnosis code 41 set?
|
|
Replace the SRS-ECU
(Refer to ).
|
|
|
|
An intermittent
malfunction is suspected (Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service
Points ).
