dicator light should come on within lour minutes.
. lf the light does not come on. remove the access
panel and disconnect the 3P connector from the
fuel gauge sending unit. Connect the A (BLV
WHT) terminal to the C (BLU,/WHT) terminal with
a jumper wire.
- lf the Iight comes on, the problem is either the
sending unit or its ground.- lf the light does not come on, the problem is
an open in the BLU/WHT wire to the gauge as-

The SRS is a safetv device which, when used in coniunction with the seat belt, is designed to help protect the driver and
front passenger in a frontal impact exceeding a cenain set limit. The system consists ot the SRS unit (including safing sen-
sor and imDact sensor), the cable reel, the driver's airbag, and front passenger's airbag
Operation t'Its
The main circuit in the SRS unit senses and judges the force ot impact and, il necessary, ignites the inflator charges. If bat-
tery voltage is too low or power is disconnected due to the impact, the back-up power circuii will keep voltage at a con-
stant level.
For the SRS to operate:
(1) The impact sensor and safing sensor must activate and send electric signals to lhe mictop.Goi
{2) The microprocessor must compute the signals and send signals to the airbag inflators'
(3) The inflators must ignite and deploy the airbags sE Lr.r

Self-diagnosis System
A self-diagnosis circuit is built into the sRs unit; when the ignition switch is turned oN (ll), the sRS indicator light comes
on and goes off after about six seconds if the system is operating normally'
lf the light does not come on, or does not go off after six seconds, or if it comes on while driving. it indicates an abnormal-
ity in the system. The system must be inspected and repaired as soon as possible'
For better servicesbility. the memory will store the cause of the malfunction, and the data link circuit passes on the infor-
mation from the memory to the data link connector (DLC). This information can be read with the Honda PGM Tester con-
nected to the DLc (16P).

Power Distribution Schematics
From Fuses to Relays and Components
The second half of Power Distribution shows the wiring "From Fuses to Relays and
Components." This can speed your troubleshooting by showing which circuits share fuses. lf
Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a
component in the other circuit. lf it works, you know the fuse is good and power is available to
the inooerative circuil.
