8-142 METERS AND GAUGES - EGR Warning System
EGR WARNING SYSTEM
The EGR warning system consists of a microswitch connected
to the odometer, a reset switch, and a warning light bulb.
This system will cause the EGR warning light to light up every
50,000 miles that the vehicle is driven in order to inform the
driver that it is time to check the EGR system.
The warning light bulb will light up when the ignition switch is
set to “ON” while the engine is not running, thus allowing the
driver to confirm that the bulb is not burned out.
RESET SWITCH
Use the switch on the back of the odometer to reset the EGR
warning system.
NOTE
If the speedometer is to be replaced, set the new odometer to
the same reading as the odometer being, removed.

SPECIFICATIONS
GENERAL SPECIFICATIONS VEHICLE-SPEED SENSOR (REED-TYPE SWITCH)
The vehicle-speed sensor functions to substitute pulse signals
for the rotations (vehicle speed) of the transmission’s output
gear;/ t i is located within the speedometer.
Pulse signals are generated when the speedometer cable
rotates.
AUTbMATlC FREE-WHEELING HUB INDICATOR
CONTROL UNIT
The control unit is located at the upper part of the right cowl
side.
The control unit is composed of the pulse-detection circuit
(which receives the input signals from the pulse generator),
the vehicle-speed-detection circuit (which receives the input
signals from the vehicle-speed sensor), the lock-discrimination
circuit (which, based on both of these input signals, judges the
condition of the automatic free-wheeling hub ‘and then trans-
mits indicator output signals to the memory circuit), and the
memory circuit (which “memorizes” the indicator output
signals from the lock-discrimination circuti).
