A Vehicle Immobilizer is a device used to prevent vehicles from being accessed by unauthorized users and maintain electronic security. It works by vehicle’s engine system, starter making it only start with the authorized key. A Vehicle Immobilizer is used to increase vehicle safety and enhance security.
Test Procedure
Connect Ignition supply voltage to red wire w.r.t. ground i.e. 9V to 36V DC, variable power supply
Connect Tracker digital output signal to green wire w.r.t ground on 5V to 12V @10mA
Connect multimeter probes to the blue wire on the continuity test
Gives the 9V DC supply to the red wire w.r.t. Black wire, When supply is 9V DC and test the continuity on the blue wire and Red Wire it is NO (Normally Open) and test the continuity on the blue wire and Black Wire it is NC Normally Close)
Measure the voltage at yellow wire w.r.t. ground, It should be w.r.t red wire supply voltage. (Please consider voltage drop across the diode)
The next step is to apply the 5V To 12V @10mA supply to a green wire
Relay contact should be changed after time delay of 2 Second NO (Normally Open) to NC (Normally Closed) and NC (Normally Closed) to NO (Normally Open)
6 lines on Immobilizer
To know through one Digital Input to VTS that the immobilizer is connected i.e. 5V DC (1 Line)
To the Immobilizer from VTS i.e. One Digital Input Signal @ 5V To 12V @10mA (1 Line)
