Transmitter Test
NOTE:
. lf the doors unlock or lock with the transmitter, but
the LED on the transmitter does not come on, the
LED is faulty; replace the transmitter.
. lf any door is open, you cannot lock or unlock the
door with the transmitter.
. lf you unlocked the doors with thetransmitter, but do
not open any of the doors within 30 seconds, the
doors relock automatically.
. The doors do not lock or unlock with the transmitter
if the ignition key is inserted in the ignition switch.
1. Using a keyless entry checker (07MAJ - SP003001:
. Place the transmitter on the keyless entry check-
er, and press the transmitter button.
- lf the indicator light does not come on, check
for:- a dead or low batterv- Faulty transmitter- lf the ray indicator light comes on, the trans-
mitter is OK.

Storing Transmitter Codes
. The codes of up to four transmitters can be stored in the control unit. {lf a {ifth code is stored, the code which was
stored tirst will be erased.)
. When the system enters the registration mode, all previously slored codes will be erased.
. The system leaves the registration mode and returns to the normal mode if you
- turn the valet swirch OFF, or
- turn the ignition switch OFF, or
- do not press the transmitter button for more than 10 seconds
Procedure:
NOTE: lt is important to maintain the time limits between steps

NOTE: lf the tuner is turned ON, it willgo off and come on again when the reg-
istration procedure is completed-

NOTE: lf you want to register the codesof more than one transmitter, repeat step4 within 10 seconds with the next trans'mitter.
NOTE: After storing its code, make sure

Description
)
The sRS is a safety device which, when used in coniunction with the seat belt, is designed to help protect the driver land
front passenger) in a frontal impact exceeding a certain set limit. The system consists of the sRS unit {including safing
sensor and impact sensor), the cable reel, the driver's airbag (and front passenger's airbag)

Operation
The main circuit in the SRS unit senses and judges the force of impact and, if necessary, ignites the inflator charge(s) lf
battery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power clrcult
resoectivelv will keep voltage at a constant level.
For the SRS to operate:
(1) The impact sensor must activate. and send electric signals to the mlcroprocessor'
(2) The microprocessor must compute the signals' and must send signals to the airbag inflator(s)'
{3) The inflator(s) must ignite and deploy the airbag(s)'

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 liglt 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 serviceability, the memory will store the cause of the malfunctlon, and the data link circuit passes on the infor-
mation from the memory to the data link connector (DLC). This intormation can be read with the Honda PGM Tesler con-
nected to the DLC (16P).
