P.28 Installation guide

TroubleshootingPoorTransmittingRange

In order to ensure optimal range, the antenna should be installed at least 7.5 cm (3 in.) from the roof –

2.5 cm (one inch) below the tint strip is generally the best location. Install the antenna as far as possible

from radio antennas, GPS, Onstar® or factory compasses.

Many factors may affect the operating range of the transmitter. Some of these are:

• The condition of the battery in the transmitter.

• The operating environment (for example: downtown radio-frequency noise, airports, cellular

phone towers…)

• Metal: any type of metal will affect operating range. This includes the metal in the car.

• The shape of the vehicle can affect range as well; vans in general have an especially poor

range.

• The shape of the roof and A-pillars brings about considerable radio-frequency deflection (in

this case the signal from the remote control). As a result, the direction in which the vehicle is

facing in relation to the remote control can affect the range. Straight on – standing in front of

the vehicle – generally gives you the greatest range; the second best performance is from

the back. Using the remote control from either side of the vehicle will usually give the lowest

range.

• The range will be significantly lower in a crowded parking lot than in open space.

• Always hold the transmitter high, approximately at shoulder height. Holding the transmitter

against your chin will also increase your range: your head acts as an antenna.

• The operating range will be somewhat lower on vehicles equipped with an aftermarket or

factory alarm.

• Windows and windshields tinted with lead or metallic tints will decrease the operating range.

• The antenna cable may have been cut and/or is grounded out on the chassis. Try using

another cable.

• The receiver may be faulty. Try replacing it with another.

Testing

Before putting the vehicle back together, it is recommended to check that the system operates properly.

The following testing procedures should be used to verify proper installation and operation of the system.

Before testing, make sure that all connections are soldered and that the unit is plugged in.

 If installed on a MANUAL transmission, make sure the system properly enters and exits

ready mode (see earlier in this Guide).

 Remote-start the engine and listen for starter drag. If the starter cranks for too long, carry out

another tach programming procedure.

 Hood switch shutdown. With the vehicle running under the remote car starter, open the hood; the

vehicle should shut down. If it does not shut down, check the hood pin-switch and its connector.

 Brakes shutdown circuit. With the vehicle running under the remote car start, press and release

the brake pedal. The engine should shut down immediately. If the engine continues to run, check

the brakes switch connection.
