TESTING FOR ªSHORTSº IN THE CIRCUITNJGI0005S0303To simplify the discussion of shorts in the system please refer to
the schematic below.
SGI847
Resistance Check Method
1) Disconnect the battery negative cable and remove the blown
fuse.
2) Disconnect all loads (SW1 open, relay disconnected and sole-
noid disconnected) powered through the fuse.
3) Connect one probe of the ohmmeter to the load side of the fuse
terminal. Connect the other probe to a known good ground.
4) With SW1 open, check for continuity.
continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.
5) Close SW1 and disconnect the relay. Put probes at the load
side of fuse terminal and a known good ground. Then, check
for continuity.
continuity; short is between SW1 and the relay (point B).
no continuity; short is further down the circuit than the relay.
6) Close SW1 and jump the relay contacts with jumper wire. Put
probes at the load side of fuse terminal and a known good
ground. Then, check for continuity.
continuity; short is between relay and solenoid (point C).
no continuity; check solenoid, retrace steps.
Voltage Check Method
1) Remove the blown fuse and disconnect all loads (i.e. SW1
open, relay disconnected and solenoid disconnected) powered
through the fuse.
2) Turn the ignition key to the ON or START position. Verify bat-
tery voltage at the B + side of the fuse terminal (one lead on
the B + terminal side of the fuse block and one lead on a known
good ground).
3) With SW1 open and the DMM leads across both fuse
terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).
no voltage; short is further down the circuit than SW1.
4) With SW1 closed, relay and solenoid disconnected and the
DMM leads across both fuse terminals, check for voltage.
voltage; short is between SW1 and the relay (point B).

+The ªAIR BAGº warning lamp does not illuminate when the
ignition switch is turned ªONº.
+The ªAIR BAGº warning lamp does not go off about 7 seconds
after the ignition switch is turned ªONº.
+The ªAIR BAGº warning lamp blinks after about 7 seconds after
the ignition switch is turned ªONº.
2. Visually check SRS components.
1) Diagnosis sensor unit
+Check diagnosis sensor unit and bracket for dents, cracks and
deformities.
+Check connectors for damage, and terminals for deformities.
2) Air bag module and steering wheel
+Remove air bag module from steering wheel, instrument panel
or seatback. Check harness cover and connectors for damage,
terminals for deformities, and harness for binding.
+Install driver air bag module to steering wheel to check fit or
alignment with the wheel.
+Check steering wheel for excessive free play.
+Install front passenger air bag module to instrument panel to
check fit or alignment with the instrument panel.
+Install front side air bag module to seatback to check fit and
alignment with the seat.
3) Spiral cable
+Check spiral cable for dents, cracks, or deformities.
+Check connectors and protective tape for damage.
+Check steering wheel for noise, binding or heavy operation.
4) Main harness, body harness, side air bag module sub-harness
+Check connectors for poor connections, damage, and termi-
nals for deformities.
+Check harnesses for binding, chafing or cut.
5) Front seat belt pre-tensioner
+Check harness cover and connectors for damage, terminals
for deformities, and harness for binding.
+Check belts for damage and anchors for loose mounting.
+Check retractor for smooth operation.
+Perform self-diagnosis for seat belt pre-tensioner using ªAIR
BAGº warning lamp or CONSULT-II.
Refer to ªSRS Operation Checkº for details. (RS-59)
6) Side air bag (satellite) sensor
+Check side air bag (satellite) sensor (including bracket portion)
for dents, cracks or deformities.
+Check connectors for damage, and terminals for deformities.
CAUTION:
Replace previously used special bolts, hex bolts and ground
bolt with new ones.
