SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-167
STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the
."
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES : Go to Step 2.
NO : Repair the CAN bus line (Refer to GROUP 54C,
).
STEP 2. Check the side impact sensor. (Using scan tool
MB991958, read the diagnostic trouble code.)
(1) Disconnect the negative battery terminal.
(2) A side impact sensor is checked in the following way.
• Replace the side impact sensor (front) (LH) {In case of
code B1B72 (Regardless of "Active" or "Stored" faults)}
with the new part.
• Replace the side impact sensor (front) (RH) {In case of
code B1B75 (Regardless of "Active" or "Stored" faults)}
with the new part.
(3) Connect the negative battery terminal.
(4) After erasing the diagnostic trouble code memory, check the
diagnostic trouble code again.
Q: Is either DTC B1B72 or B1B75 set?
YES : Go to Step 3.
NO : The procedure is complete.

SRS AIR BAG DIAGNOSIS
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-168
STEP 3. Check the SRS-ECU (Using scan tool MB991958,
read the diagnostic trouble code.)
(1) Disconnect the negative battery terminal.
(2) Replace the SRS-ECU with a new one. (Refer to
(3) Connect the negative battery terminal.
(4) Check the diagnostic trouble code again.
Q: Is either DTC B1B72 or B1B75 set?
YES : Return to Step 1.
NO : The procedure is complete.
DTC B1B73: Malfunction of G-sensor Inside Side Impact Sensor (Rear) (LH)
DTC B1B76: Malfunction of G-sensor Inside Side Impact Sensor (Rear) (RH)
CAUTION
If DTC B1B73 or B1B76 is set in the SRS-ECU,
always diagnose the CAN main bus line.
.
DTC SET CONDITIONS
These DTCs are set if the following conditions 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 output is abnormal.
.
TROUBLESHOOTING HINTS
Malfunction of side impact sensor (rear) (LH) (for
DTC B1B73) and impact sensor (rear) (RH) (for DTC
B1B76)
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A (Vehicles with
CAN Communication System)
