DRIVE-CONTROL COMPONENTS - ABS
ANTI-LOCK BRAKE SYSTEM (ABS) N73ZNaQM
The ABS used in the 1995 Eclipse is similar to
the previous one. The AWD version ABS is a 4-sensor, 2-channel
type and is the same as the FWD system except
Combining the ABS with the AWD system has signifi-
for the following respects.

Part name No. Function
Wheel speed sensor 1 Sends an AC signal with a frequency proportional to the ro-
tating speed of the individual wheel to the ABS-ECU.
Sensor G-sensor 2 Sends an ON/OFF signal to the ABS-ECU depending on
vehicle acceleration/deceleration.
Stop light switch 3 Sends a signal to the ABS-ECU indicating whether the
brake pedal is pressed or not.
Controls braking pressure for each wheel depending on the
Hydraulic unit (HU) 4 signal from the ABS-ECU.
Includes built-in select-low valve
ABS power relay 5 Supplies power to the ABS-ECU.
Motor relay 6 Closes contact in response to a signal from the ABS-ECU to
Actuator allow the power to be supplied to the motor in the HU.
Valve relay 7 Is turned ON by the ABS-ECU signal and supplies power to
the solenoid valve in HU.
ABS warning light 8 Is in the combination meter and lights up when there is
trouble in ABS.
Data link connector 9 Outputs diagnostic trouble codes.
Electronic control unit (ECU) 10 Controls the actuators such as HU according to the signals
- from the individual sensors.
