J can not run the diagnostics. I have checked door interlocks and they work. I have the fast blinking light and am currently checking the keypad. It appears that I have some anomalies. In some cases I get readings without pushing the switch and in others the switch does not change anything. I need to understand the nomenclature before going further, In the keyboard function table what does P 1-12 mean? 1 and 12, 1 or 12, or 1 thru 12. When checking do I need to run all combinations or just find one that works. I am taking the readings on the side as I do not have a probe small enough to go into the plug.
