Alternator sensing:

This is not voltage sensing. To use alternator sensing the engine sense input, (yellow/black) must be connected to the stator wire on the alternator. This will be a small gauge wire.

Alternator sensing procedure

(To test for alternator sensing set digital multi-meter for DC voltage. Alternator is pre-programmed in the control module and does not require programming. )

1.The stator wire will rest at 0-volts DC while the vehicle is off.

2.Turn the ignition to the run position with the key. The stator wire will test between 4 to 6-volts DC.

Start the vehicle with the key. While the vehicle is running at idle the stator wire

will test between 12 to 14-volts DC.

Diagnosing Remote Start Problems

If there is a problem auto-starting the vehicle, you will hear three chirps or see three parking light flashes when you attempt to auto-start it. Wait for 2 seconds and the cause for the error will be indicated by the number of times the parking lights flash.

Error Number	Error Reason
(# of times parking lights flash)
1	Engine On
2	Key On
3	Door Open
4	Trunk Open
5	Brake On
6	Hood Open
7	Reservation Off
	(Manual Transmission Only)
