Anybody had the C1248 code before? My service manuals say nothing about this code, its like they left out AH from the service manual in '99.

Thanks

I checked si2000 (gm's service info) c1248 does not show up for a 99 c5, i did find it for 98. dtc c1248 instrument panel cluster indicated low brake fluid. The document number is 317427, ask your local dealer tech if they will print the chart for you.The chart looks really basic, check you fluid level and your fluid level switch

Thank you! The brake fluid is low because I'm working on it. I still wanted to be sure that is the cause.
