Repair order (“Recheck SRS at each replacement.”)
1. Visually check the wiring harness connection.
2. Replace the harness if it has visible damage.
3. Replace the LH side air bag (satellite) sensor.
4. Replace the diagnosis sensor unit.
5. Replace the related harness.
* Follow the procedures in numerical order when repairing malfunctioningparts. Confirm whether malfunction is eliminated
using the air bag warning lamp or CONSULT-II each time repair is finished. If malfunction is still observed, proceed to the next
step. When malfunction is eliminated, further repair work is not required.

NOTE:
When diagnosis sensor unit is replaced with new one, “AIR BAG”
warning lamp will operate in User mode. Checking “AIR BAG”
warning lamp operation in Diagnosis mode is not required. Go to
step 6.
5. If “AIR BAG” warning lamp operates as shown in No. 1 in chart
above, turn ignition switch “OFF” to reset from Diagnosis mode
to User mode and to erase the memory of the malfunction.
Then go to step 6.
If “AIR BAG” warning lamp operates as shown in No. 2 or No.
3 in chart above, the malfunctioning part is not repaired
completely, or another malfunctioning part is detected. Go to
DIAGNOSTIC PROCEDURE 6, page RS-60, and repair mal-
functioning part completely.
6. Turn ignition switch “ON”. “AIR BAG” warning lamp operates in
User mode. Compare “AIR BAG” warning lamp operation to
the chart below.
NOTE:
When a malfunction is detected, switch from Diagnosis mode to
user mode by turning the ignition switch as follows:
1) Turn ignition switch “ON”.
2) After “AIR BAG” warning lamp lights for 7 seconds, turn igni-
tion switch “OFF” within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch “ON”.
SRS is now in User mode.
