IDM error DT570

IDMs do go bad. Make sure your fuses in the battery box are good and clean. Check the power harness from the batteries up as far as you can follow. Check your relay box under the hood for any corrosion. The IDM is what runs the injectors and will log codes when there are circuit problems. Usually when you see multiple injector codes like this, the module is going bad. Always check the wiring harness first for any rubbed spots or loose connections.

 

I would clear the codes and retest to see if they come back.

 

It could cause a hard or no start. If you do the injector test, you should hear all 6 injectors click or buzz. Those codes are for 2 and 6 open coil, so if you do not hear them click or buzz in order, then you need to look further as to why. Normally the injector coil is bad which means you need new injectors.
