SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-51
STEP 2. Check the harness wires between SRS-ECU
connector C-74 and side impact sensor (LH) connector D-
12.
Q: Are the harness wires between SRS-ECU connector C-
74 and side impact sensor (LH) connector D-12 in good
condition?
YES : Go to Step 3.
NO : Repair them. Then go to Step 3.
STEP 3. Check DTC.
Q: Is DTC 91output?
YES : Replace the SRS-ECU. Refer to
NO : This diagnosis is compleate.(If no malfunctions are
not found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use

SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-52
•
Analog G-sensor characteristics are
abnormal.
•
Analog G-sensor output is abnormal.
TROUBLESHOOTING HINTS
•
Malfunction of side impact sensor <LH> (for DTC
92) and side impact sensor <RH> (for DTC 95)
DIAGNOSIS
Replace side impact sensor <LH> (for DTC 92) and side impact
sensor <RH> (for DTC 95). Refer to
.
Q: Is any of DTC 92 or 95 output?
YES : Replace the SRS-ECU. Refer to
NO : This diagnosis is complete.(If no malfunctions are not
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use

SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-53
CIRCUIT OPERATION
•
The SRS-ECU judges how severe a collision is
by detecting signals from the side impact sensor
and the analog G-sensor. If the impact is over a
predetermined level, the SRS-ECU outputs an
ignition signal. At this time, if the safing G-sensor
is on, the SRS air bag will inflate.
DTC SET CONDITIONS
•
This DTC is output 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, DTC number 94 will be
automatically cleared and the SRS warning light
will switch off if the condition returns to normal.
TROUBLESHOOTING HINTS
•
Damaged wiring harnesses or connectors
•
Malfunction of the side air bag module (RH)
(squib)
•
Malfunction of the SRS-ECU

SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-54
STEP 1. Check the side impact sensor (RH) line at the SRS-
ECU connector C-74 by backprobing.
(1) Do disconnect the side impact sensor (RH) connector D-02
(2) Connect the negative battery terminal.
(3) Turn the ignition switch to "ON" position.
(4) Measure the voltage between terminal 4 and the ground by
backprobing.
•
Voltage should be 9 volts or more.
(5) Check the continuity between terminal 1 and the ground by
backprobing.
•
Should be less than 2 ohm.
Q: Does the voltage meet the specifications or is the
resistance less than 2 ohm?
YES : Replace the side impact sensor (LH). Refer to
NO : Go to Step 2.
