STEP 2. Check the harness wires for open circuit or short
circuit between SRS-ECU connector E-07 (terminal No.34
and 36) and side impact sensor (LH) connector F-13
(terminal No.1 and 2).
NOTE: After inspecting intermediate connector E-19 inspect
the wiring harness. If the intermediate connector E-19 is dam-
aged, repair or replace it. Refer to GROUP 00E, Harness Con-
nector Inspection
. Then go to Step 3.
Q: Are the harness wires between SRS-ECU connector
E-07 (terminal No.34 and 36) and side impact sensor
(LH) connector F-13 (terminal No.1 and 2) in good
condition?
YES : Erase the diagnostic trouble code memory, and check
the diagnostic trouble code. If DTC 91 steps. Replace
the SRS-ECU (Refer to
).
NO : Repair the harness wires between SRS-ECU
connector E-07 and side impact sensor (LH)
connector F-13. Then go to Step 3.
STEP 3. Recheck for diagnostic trouble code.
Q: Is DTC 91 set?
YES : Return to Step 1.
NO : The procedure is complete. (If no malfunctions are not
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
).

DTC 92: Left Hand Side-Impact Sensor System for Fault 1
DTC 95: Right Hand Side-Impact Sensor System for Fault 1
.
DTC SET CONDITIONS
These DTC are set if the followings are detected
from the analog G-sensor output.
• Analog G-sensor is not operating.
• 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
Required Special Tool:
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: MUT-III USB Cable
• MB991911: MUT-III Main Harness B (Vehicles without
CAN communication system)
STEP 1. Recheck for diagnostic trouble code.
(1) Replace side impact sensor <LH> (for DTC 92) and side
impact sensor <RH> (for DTC 95) (Refer to
(2) Eras diagnostic trouble code memory, and check the
diagnostic trouble code.
Q: Is any of DTC 92 or 95 set?
YES : Replace the SRS-ECU (Refer to
).
NO : The procedure is complete.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

CIRCUIT OPERATION
The side impact sensor includes an analog G sensor
and CPU, etc. The CPU monitors the analog G sen-
sor 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-airbags. 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 diagnostic trouble
code.
.
DTC SET CONDITIONS
This DTC 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. How-
ever, DTC number 94 will be automatically cleared
and the SRS warning light will switch off if the condi-
tion returns to normal.
.
TROUBLESHOOTING HINTS
• Damaged wiring harnesses or connectors
• Malfunction of the side-airbag module (RH)
(squib)
• Malfunction of the SRS-ECU
.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: MUT-III USB Cable
• MB991911: MUT-III Main Harness B (Vehicles without
CAN communication system)
• MB991223 (MB991222): Harness set (Probe)
STEP 1. Check the side impact sensor (RH) power supply
circuit at the SRS-ECU connector E-07.
(1) Disconnect the negative battery terminal.
(2) Disconnect right hand side impact sensor connector F-19,
and measure at the wiring harness.
(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 F-19 harness connector
terminal 2 and body ground.
Voltage should measure 9 volts or more.
Q: Is the measured voltage within the specified range?
YES : Replace the side impact sensor (RH) (Refer to
NO : Go to Step 2.
