The prius won't start. Only error code is P0A0D We checked continuity on the service plug, the interlock harness and to the plug from the car to the interlock, all has continuity So the only thing I can think of is that the wiring harness going to the ECU might be cut somewhere inside the car Here is my question. Has anyone jumped out the interlock pins at the ECU and which 2 pins are they?
The interlock circuit is a very simple series circuit that passes from an ECU pin, through cover interlock contacts in the inverter, back to the rear of the car, through the interlock contacts of the battery service plug, and to body ground. It is simple enough that finding the actual problem and fixing it ought to be a matter of minutes. I would consider defeating it by jumping at the ECU only as a very, very last resort.
Does the car look like wires would be cut inside of it or otherwise be fubar . This is really a stretch . A Google question will bring you up a wiring diagram of the Interlock system I do believe on the Prius from the inverter to safety plug etc . Is the fuse good in the safety plug? Like chap said it's a pretty basic system
Remove the orange safety interlock plug and reinstall it per the directions below. There are three steps to install the orange safely plug. 1. Insert the plug into the socket. 2. Flip the lever of the plug. 3. Slide the lever with some force. This last step is sometimes not completed, which will cause the code. Here is a diagram from a Gen 2 Prius. View attachment 272365
Make sure the fuse is good in that plug. Continuity beep. Slam it down last step finger hurts click. You can check with meter to see the connection is made I think it's blk and white wire
