Hi all,
Had all of these indicator lights come on (Airbag, E-brake, Batt, VSC TRAC, VSC OFF, and ABS warning lights and the fan running to full blast with any increase in engine RPM (step on the gas, climate control blower rips to full blast, let off the gas returns to low). Turning off the climate control did stop that, but indicators remain lit solid.
I did just replace both my O2 sensor and Air/Fuel sensor, but I've done that before without this happening. I replaced them due to getting a P0420 code, so my CEL and VSC lights were on already. Figured I would replace both while down there since they were replaced not too far apart last time about 7 years ago. Check engine light is now off, but all these others are now on.
From what I have seen on the forum, there have been some saying it could be ABS fluid level related, battery possibly going bad (my battery is stickered at 12/2016), although that timing would be crazy. Suppose one of the sensors could have been bad out of the box, I did not measure their resistance. I have also seen some worse things like ECU going bad, although the truck still runs and drives fine mechanically. She is approaching 300k, so who knows but she's always been so solid.
Anyway, going to auto parts store to try to get a code tomorrow morning, but wanted to throw this out here in case someone had any ideas.
