Removal and Installation
SRS components are located in this area. Review the
SRS component locations {see page 23-13) andprecautions and procedures (see page 23-14) in the SRS
section before performing repairs or service.
Removal
1. Make sure you have the anti-theft code for the radio,
then write down the frequencies for the radio's
preset buttons.
2. Disconnectthe battery negative cable, then
disconnect the positive cable, and wait at least
three minutes.
3. Remove the driver's dashboard lower cover (see
page 20-59).
4. Disconnect the connectors from the fuse side of the
under-dash fuse/relay box.
5. Remove the mounting bolt, and slide the under-
dash fuse/relay box (A) down from the bracket {B).
6. Disconnect the back side from connectors from the
back of the under-dash fuse/relay box, and remove
the fuse/relay box.
NOTE:The SRS connector is a spring-loaded lock
type (see page 23-1 1).
lnstallation
1. Installthe under-dash fuse/relay box in the reverse
order of removal and connect all connectors to the
under-dash fuse/relay box.
2. Installthe driver's dashboard lower cover.
3. Connect both the negative cable and positive cable
to the battery.

Self-diagnostic Procedure
The gauge assembly has a self-diagnosis function.. The Beeper Drive Circuit Check. The Indicator Drive Circuit ChecL. The LCD Segments Check. The Gauges Drive Circuit Check (Speedometer, Tachometer, Fuel gauge, Coolant temperature gauge). The Communication Line Check (the coolanttemperature signal line between the gauge and ECM)
NOTE: Indicators are also controlled via the communication line.
Entering the self-diagnosis f unction:
Before doing the self-diagnosis function, check the No. 9 (10A) fuse in the under-hood fuse/relay box and No. 10 {7.5A)fuse in the under'dash fuse/relay box.
1. Push and hold the trip/reset button.
2. Turn the lighting switch ON.
3. Turn the ignition switch ON (ll).
4. Within 5 sec., turn the lighting switch OFF, then ON and OFF again.5. Within 5 sec., release the trip/reset button, then push and release the button four times reDeatedlv.
NOTE:. While in the self-diagnosis mode, the dash lights brightness controller operates normally.'Whileintheself-diagnosismode,thetrip/resetbuttonisusedtostartthebeeperdrivecircuitcheckandthegauge
