Immobilisers

[quk@sievers.com (Phil Payne)]

As it seems that information about dumping engine codes is going to become more 
public, I thought I'd air a warning to the list.
 
Using a variant of the standard procedure, it's possible to work out why an 
engine won't start.  If you have installed an immobiliser by, e.g., cutting 
into the flywheel sensor wire or the Hall effect sensor wire, this can be 
determined very rapidly using the procedure.
 
It's essential that any immobiliser used on a car with one of the later ECUs 
also disables the starter motor in one of the fairly sophisticated ways known 
to installers.

Just a caution.
