Battery lamp only illuminates during initial lamp test when ignition is turned on, before cranking. It doesn't come on to accompany the P0562 code. Once engine is started, battery voltage immediately goes to ~14.15vdc +/- 0.1vdc, depending on accessories active. If I disconnect battery to reset codes, all is fine, with no codes (checked with Innova 3100 code checker) until 3rd or 4th start after 1-2 days pass. I'll check all connectors and open an Alldata account to troubleshoot harness in depth if needed.
Is code being set by disconnecting battery to clear codes? My code checker can't reset codes, so I have to resort to battery disconnect method.
I hope it's not the PCM. Years ago I had a Mitz Mirage that died due to leaking caps on the PCM. IT wasn't worth the replacement cost to keep the old car.
