If the TECH 1 displays ARM 0 V
before the first test step, the electronic immobilizer is still armed. It may
also be necessary to depress the middle button several times (twice or three
times) for the above test steps before the system reacts.
Ensure that a programmed
infrared key transmitter is used (see test steps 21 and 22).
The red LED in the infrared key
transmitter must illuminate every time the button is depressed (if not, this
means that the batteries are flat).
