11:28. Removal and installation of sensors of accelerations (G-sensors)

Details of installation of G-sensors on the all-wheel drive Galant models for 1993 the issue.

Forward G-sensor

1 — the Contact socket of an electrical wiring
2 — the Forward sensor of acceleration
3 — the Basic arm of the sensor

Back G-sensor

4 — the Contact socket of an electrical wiring

5 — a G-sensor Cover
6 — the Back sensor of acceleration
7 — the Basic arm of the sensor


G-sensors are used only on all-wheel drive (AWD) models and are installed in the luggage compartment under a carpet (the back sensor) and under assembly of the central console in interior of the car (the forward sensor). Sensors transfer information on the overloads arising during dispersal or braking of the vehicle to ECU ABS. The analysis of the arriving signals together with the data accepted from wheel sensors, and information on working parameters of the power unit allows ECU to define reliability of coupling of protectors of wheels with a paving and to exercise control of functioning of the hydraulic modulator taking into account this factor.

Removal

 PERFORMANCE ORDER

1. Remove assembly of the central console (the forward sensor) / a carpet in the luggage compartment (the back sensor).
2. Disconnect an electrical wiring from the sensor.
3. Uncover with the sensor (the back sensor).
4. Remove the sensor from a basic arm. In case of need dismantle as well an arm.


Installation

 PERFORMANCE ORDER

1. If removed, establish into place a basic arm of the sensor.
2. Install the sensor on an arm and connect to it an electrical wiring. Tighten fixing bolts with the required effort (11 H • м).
3. Establish a sensor cover (the back sensor).
4. Establish into place console assembly / carpet of the luggage compartment.
