I've seen the TH relay but have never read about it. I always figured that the component on the end of the wires in the tank would change resistance (...

Where at on the backplane? I've never seen a VM not jumped.... yes they're orange. Which ones are the good ones to replace them with?

Not sure I know how to do the confidence test. I did the FLTP check on the PMIs and had no faults.

You don't have just the reader and PCB available do you?

I also hate running cars full speed into the buffers.

Why do I always forget to check for AC component??? I guess because I'm used to working on old relay stuff..... Thanks , I'll crank up the 5V a little...

I checked all the power supply voltages today, all were ok except the 5V was a little low at 4.970. I cranked it up to 5.012. Measuring at the DSP PCB...

F904 which is low line fault I believe. I think it's power related but can't prove it yet. Sometimes it traps people and/or I get there and it's OOS. ...

It does mean it's hot but, it's looking at the K55 signal. Look at the K55 LED signal on the prints.

I agree danzeitz. It's a better way than the old fashion ones.

They are on a CAN BUS with these kind of PB's.

Thanks. I thought they were red, maybe orange. I've seen them on LRV's but they are on lot's of different equipment now.

I would of thought you used IMS.
