JaegerCANtrol© Digital Control Module - Diagnostics

The JaegerCANtrol© Digital module has now been upgraded with the addition of a diagnostic LED at the back of the module.

This LED will show various signals in RED or GREEN to indicate normal operation or fault modes.

This now allows the installer to quickly diagnose any possible connection or fitment issue. They guide you in the direction of the most likely connection issue such as a broken earth or power connection as well as possible CAN signal connection issues.

It can sometimes take time to identify if the problem is due to a CAN signal error or a power/earth error. With this new system you will quickly know which connection issue it might be.

On vehicles with a two wire CAN (Excludes GM based vehicles that use only 1 wire) it is very easy to get the CAN High and CAN Low connections mixed up. This new LED will quickly tell you if this is the case.
