2. Turn the ignition swilch ON (ll). The SRS indicator light comes on for about six seconds and then goes off. Then it will
indicate the DTC:- The DTC consists of a main code and a sub-code.- Including the most recent problem, up to three different malfunctions can be indicated.- ln case of a continuous failure, the DTC will be indicated repeatedly (see example 1 below).- In case of an intermiftent failure, the SRS indicator light will indicate the DTC one time. then it will stay on (see exarn-ple 2 beiow).- lf both a continuous and an intermittent failure occur, both DTCS will be indicated as continuous failures.- In case the system is normal (no DTC), the SRS indicator light will stay on {see example 3).

How the Circuit Works
The maintenance reminder light comes on to
remind the driver that the car is due for
scheduled mainlenance.
The maintenance reminder unit receives a vehicle
speed input from the vehicle speed sensor (VSS)
and uses this inlormation to compute the distance
traveled. For the first 6000 t 1 00 miles (9650 t 160
km) after the maintenance reminder light is reset, it
will come on for two seconds when you turn the
ignition switch to ON (ll) as a bulb check.
Between 6000 1 100 miles (9650 t 160 km) and
7500 t 100 miles (12070 I 160 km) the reminder
light will come on for two seconds when you turn
the ignition switch to ON (ll), and then flash for eight
seconds more.
Beyond 7500 t 100 miles (12070 t l60 km) the
reminder light will stay on when the ignition switch is
in the ON (ll) position until the unit is reset.
To reset the unit, the car must be parked and the
ignition switch in the ON (ll) position. Press the
reset button on the unit and hold it there for more
than three seconds, and the reminder light will
go off.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
