INSPECTION PROCEDURE
HINT:
1 CHECK STEERING PAD (DRIVER SIDE SQUIB 2ND STEP)
CAUTION: Never connect a tester to the steering pad (driver side squib 2nd step) for measurement, as this may lead to a serious injury due to airbag deployment.
NOTICE: Do not forcibly insert the SST into the terminals of the connector when connecting.
Insert the SST straight into the terminals of the connector.

Data list / active test
1. DATA LIST
HINT:
Using the intelligent tester to read the DATA LIST allows
the values or states of switches, sensors, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered ...
Disassembly
1. FIX FRONT SHOCK ABSORBER WITH COIL SPRING
(a) Install 2 nuts and a bolt to the bracket at the lower
side of the front shock absorber with coil spring and
secure it in a vise.
2. REMOVE FRONT SUSPENSION SUPPORT SUBASSEMBLY LH
(a) Using SST, compress the front coil spring LH
