Side Marker/Turn Signal/Hazard Flasher System

Description

To cope with dimensional requirements for the airbag components and to offer better operational feel, the turn signal

lever and the cancel mechanism are separated mechanically, and connected electrically instead.

The system cancels the turn signals electrically, by means of a solenoid, after a turn is made. A sensor mechanism which

consists of cancel cams on the steering shaft and a pair of switches, is used to monitor the steering shaft's position.

TURN SIGNAL LEVER

SOLENOIDProCarManuals.com

A cam plate is installed around the steering shaft. A pair of switches (A and B) are installed beside it.

When the steering is turned in direction of the arrow, switch A turns on first.

Then switch B turns on.

The cancel unit monitors the on-off sequence of both switches. Once it receives a full set of signals for a right or left

turn, it energizes the solenoid which then moves the turn signal lever back to neutral.

Turn Signal/Hazard Relay Input Test

1. Remove the dashboard lower cover. Remove the

turn signal/hazard relay from the left kick panel,

then disconnect the 6P connector.

2. Inspect the connector and socket terminals to be

sure they are all making good contact.

If the terminals are bent, loose or corroded, repair

them as necessary, and recheck the system.

If the terminals look OK, make the following input

tests at the connector.

— If any test indicates a problem, find and cor-

rect the cause, then recheck the system.

— If all the input tests prove OK, the control unit

must be faulty; replace it.

If the proper key has been used, the starter cut relay will be energized, and the ECM will energize the fuel supply sys-

tem. The immobilizer indicator light in the gauge assembly will simultaneously come on for about two seconds, then

go off, thereby signaling that the immobilizer unit has recognized the code sent by the transponder.

If a key has been used whose code was not received or recognized by the unit, or which was not approved by Acura,

the indicator light will come on for about two seconds, then it will blink continuously.

If the ignition switch is turned OFF, the indicator will blink for about five seconds to signal that the unit has been set

correctly, then the indicator will go off.
