Dp fix- help identify 19 and 20 wire...

DailyN54 · 07-31-2016, 01:20 PM

Apparently who ever had my car before me had a piggy back on it. I noticed the ecu box tabs were broken. Anyways, I was installing a dp fix and notice the instructions said that the #19 wire has writing on it. However mine is solid yellow. Number 20 has writing on it also yellow wire. I was using the BMS instructions and don't know if this is a typo or if the previous owner may have mixed up the wires. I was getting a strange 02 code from time to time p2c7b. If you know which one is supposed to have writing on it please let me know.

Thank you for your help.

I'm pretty sure they got the pins swapped.

The last person who had the piggyback in it probably mixed them up. I did it once and caught it when I was putting my dbfix in once and switched them back.

Okay cool. So the JB4 instructions for the dp fix is correct?

Just put back where they were before you installed dpfix. It varies apparently. My yellow wires (like yours) are opposite from dpfix instructions. If reversed you will get "check sum" code.
