OEM remote starter detection
If the vehicle has an active OEM remote starter it will program into convenience only (no immobilizer bypass). The reason
for this is to allow aftermarket security to be installed while keeping the factory remote starter active. If you wish for the
interface to control the remote start sequence, perform one of the following:
How to know if the vehicle is equipped with an OEM remote starter:
1- An “ENGINE STARTER”
sticker should be on the remote.
ENGINE
STARTER
x2
&
Press & Hold
for 3 seconds
2- Remote start the OEM remote starter:
Press the remote control’s lock button twice within 2 seconds, then press and hold the
lock button for 3 seconds.
ENGINE
STARTER
x2
&
Press & Hold
for 3 seconds
The parking lights flash after 3 seconds. The engine starts and the parking lights flash
repeatedly for 20 seconds.
If the vehicle is equipped with an Add-On Lexus/Toyota OEM remote starter
: The factory remote starter must be
permanently disconnected before programming the Directed interface as both modules cannot coexist. See locating the
OEM Remote Start on page 5.
If the vehicle is equipped with a BCM Enabled Lexus/Toyota OEM remote starter:
The vehicle does not have a physical
remote starter and only one module can be programed at a time. In this case temporally disable the OEM remote start
system using the following process:
1. Remove the fuse powering the OEM Remote Starter. See locating the fuse powering the OEM Remote Starter on
page 5.
2. Perform a module reset, see page 33.
3. Perform the Module Programming steps on page 30.
4. After programming is successful replace the fuse powering the OEM Remote Starter.
To remote start the engine, the hood, hatch, and all doors must be closed.
Unless specified otherwise, all connectors are displayed from the wire side, with the exception of the OBDII diagnostic
connector.
Refer to the "Vehicle wiring reference chart" following each installation type.
