Codes p01518, 1516, 2108, 0220 0120 and U0107

At the ignition switch, a white runs from the switch to the ignition 0 fuse. From there, it sends power to both the PCM and TCM. See pic 1 below. Check to see if there are any issues with power getting to its destination.

Let me know.

Hi,

I haven't heard from you for a couple of days. I was thinking of what you're dealing with and wondering if you have been able to make any progress. Just interested in knowing.

Regardless, I hope all is well. If you get a chance, let me know.

Take care,

Joe

Hi,

I just sent an email related to cycling the switch to turn it off. I sent it to the site owner. Hopefully, he will have some ideas to help.

As far as your requests, here is what I did. Pics 1-3 are the diagnostics specific to the B1001. Pics 4-7 are the wiring schematics for the instrument panel, and oil pressure switch. The last 4 pics are of the restraint circuits.

I hope this helps.

Let me know what I can do to help.

Take care,

Joe

Hi,

I spoke with Ken, and he is recommending having the can-bus scanned. By chance, do you know if any of the transmission codes are still active? (Or any other code)

When you think about it, as metal components warm, they expand. It's almost like when they expand, a connection is being made and it works normally. Since cycling the key eventually turns it off, I'm wondering if it is in the PCM or BCM. Ken indicated the same. That is why he would like you to scan the can system. Here is a link that shows how it's done. If you have already done this, let me know if there are codes and what they are.

Also, you indicated the dash lights flash. Are you referring to the warning lights or the illumination lights (back lights)?

Let me know.
