TITLE:RS3OOO TVIP AUTOMATIC DOOR LOCK FEATURE PROGRAMMING

MODELS:All Models
Introduction

As a convenience feature, the RS3OOO TVIP system is programmed to automatically lock all of the vehicle's doors (for vehicles equipped with powerdoor locks) when the ignition key is turned to "ON" or "START", and unlock them when the key is turned back to "ACC" or "LOCK". The initial factorysetting of this programmable feature is "ON". For some customers however, this feature is not desirable due to instances of passenger lockout when thedriver enters the vehicle first and starts the ignition.

For vehicles equipped with RS3OOO TVIP, this bulletin advises the dealers to communicate the following information to the customers at vehicledelivery:

1. Inform the customers of the RS3OOO system's automatic (ignition controlled) door lock/unlock feature.

2. Inquire about the customers' preference for it to be set "ON" or "OFF".

3. Reprogram the feature's setting according to the customer's preference.
To change the feature's operation mode, follow the programming procedures.

Verification of the Dealer-Installed Option (DIO) or Port-Installed Option (PIO) RS3OOO TVIP System can easily be performed by identifying thestatus monitor and remote transmitter.

The remote transmitter has two buttons, Top and Bottom.

PROGRAMMING PROCEDURE
AUTOMATIC (IGNITION-CONTROLLED) DOOR LOCKING/UNLOCKING FUNCTION
The factory setting for the AUTOMATIC DOOR LOCKING/UNLOCkING FUNCTION is "ON".
To change this feature's operation, follow the steps below:

1. Sit in the driver's seat with driver's door open.

2.
Insert the key into the ignition switch, and turn it to 'ON" position (not "ACC") 5 times (ON > LOCK > ON > LOCK> ON > LOCK > ON>LOCK > ON) within a 10 second period.

System Response: The STATUS MONITOR's LED turns on, and the PIEZO BUZZER sounds once.

NOTE:

You must perform the next steps within 30 seconds.

3. Select the customer's preferred operating mode.

The ground points circuit diagram shows the connections from all major parts to the respective ground points.
When troubleshooting a faulty ground point checking the system circuits which use a common ground may help you identify the problem ground quickly.

The relationship between ground points (EA, IB and IC shown) can also be checked this way.

How to Read Power Source

How to Read Power Source

The "Current Flow Chart", describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to.
The chart shows the route by which current flows from the battery to each electrical source (Fusible Link, Circuit Breaker, Fuse, etc.) and other parts.

In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams startfrom the power source, the power source system must be fully understood.

Continuity And Resistance Check

A. Disconnect the battery terminal or wire so there is no voltage between the check points.B. Contact the two leads of an ohmmeter to each of the check points.

Continuity And Resistance Check

If the circuit has diodes, reverse the two leads and check again.
When contacting the negative lead to the diode positive side and the positive lead to the negative side, there should be continuity.
When contacting the two leads in reverse, there should be no continuity.

Continuity And Resistance Check

C. Use a volt/ohmmeter with high impedance ( minimum) for troubleshooting of the electrical circuit.10 k ohm/V
