SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-155

NOTE:

After inspecting intermediate connector D-31 <L.H.
drive vehicles> or D-44 <R.H. drive vehicles> inspect
the wiring harness. If the intermediate connector
D-31 <L.H. drive vehicles> or D-44 <R.H. drive
vehicles> is damaged, repair or replace it. Then go to
Step 3.

Q: Is the check result normal?

YES :

Erase the diagnosis code memory, and

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

P.52B-178

). Then go to Step 3 .

NO :

Repair the harness wires between
SRS-ECU connector C-114 (terminal No.34
and 36) and side impact sensor (LH)
connector D-27 (terminal No.2 and 1). Then
go to Step 3.

STEP 3. Check whether the diagnosis code is
reset.

Q: Is diagnosis code 91 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

Code No.92: G-sensor of side impact sensor (LH) failure Code No.95: G-sensor of side impact sensor
(RH) failure

DIAGNOSIS CODE SET CONDITIONS
These diagnosis codes are set if the followings are
detected from the analog G-sensor inside the side
impact sensor output.

•

Analog G-sensor is not operating.

•

Analog G-sensor characteristics are abnormal.

•

Analog G-sensor inside the side impact sensor
output is abnormal.

PROBABLE CAUSE
Malfunction of side impact sensor (LH) (for diagnosis
code 92) and side impact sensor (RH) (for diagnosis
code 95)

DIAGNOSIS PROCEDURE
Replace side impact sensor (LH) (for diagnosis code
92) and side impact sensor (RH) (for diagnosis code
95). (Refer to

P.52B-186

).

Check the diagnosis code.

Q: Is any of diagnosis code 92 or 95 set?

YES :

Replace the SRS-ECU (Refer to

P.52B-178

).

NO :

The procedure is complete.

TROUBLESHOOTING

OPERATION
The side impact sensor includes an analog G sensor
and CPU, etc. The CPU monitors the analog G
sensor output signal. If the CPU judges that the side
air bags should be deployed, it sends a fire signal to
the SRS-ECU to deploy the side air bags. Besides
that, the CPU diagnoses the internal components of
the side impact sensor. If a malfunction occurs, it
requests the SRS-ECU to set a diagnosis code.

DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set if the power supply voltage
of the side impact sensor (RH) drops below the rated
value for a continuous period of 5 seconds or more.
However, diagnosis code number 94 will be
automatically cleared and the SRS warning lamp will
switch off if the condition returns to normal.

PROBABLE CAUSES

•

Damaged wiring harnesses or connectors

•

Malfunction of the side air bag module (RH)
(squib)

•

Malfunction of the SRS-ECU

DIAGNOSIS PROCEDURE

STEP 1. Measure the voltage at the side impact
sensor (RH) connector D-41.
(1) Disconnect the negative battery terminal.

(2) Disconnect side impact sensor (RH) connector

D-41, and measure at the wiring harness side.

(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 the D-41 harness

side connector terminal 2 and body earth.

OK: 9 V or more

Q: Is the check result normal?

YES :

Replace the side impact sensor (RH) (Refer

to

P.52B-186

). Then go to Step 3.

NO :

Go to Step 2.

STEP 2. Check the harness wires for open circuit
or short circuit between SRS-ECU connector
C-114 (terminal No.40 and 42) and side impact
sensor (RH) connector D-41 (terminal No.1 and
2).

Q: Are the harness wires between SRS-ECU

connector C-114 (terminal No.40 and 42) and side

impact sensor (RH) connector D-41 (terminal No.1
and 2) in good condition?
YES :

Erase the diagnosis code memory, and

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

P.52B-178

). Then go to Step 3 .

NO :

Repair the harness wires between
SRS-ECU connector C-114 (terminal No.40
and 42) and side impact sensor (RH)
connector D-41 (terminal No.1 and 2). Then
go to Step 3.

STEP 3. Check whether the diagnosis code is
reset.

Q: Is diagnosis code 94 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
