ODB1 trouble codes.. need help!

Postby Bassistofbodines [OP] » July 15th 2011, 4:56am

I was driving my van home today when I noticed the brake light started flashing. It flashes 8 times then holds on the 9th flash... Any idea what this means? And what I have to do to make it stop? thanks a lot!

How are your brakes working ? as this is usually an indicator that something has gone wrong with the braking system ,,,,,proportioning valve damage or some other malfunction , if it be OBD related a code will be stored in the memory ,

I had that exact same thing happen to the brakes on my 1988 silverado. It was traced back to a false alarm. People on the forums told me it was the switch under the pedal

Should never be mushy.

I like changing out calipers at 100K whether I think they need to or not. Calipers frequently cycle between cold and hot and I treat them as maintenance items. Rebuilt units are cheap and mine came with lifetime guarantee from Advanced Auto. I also replaced the hydro boost unit with one bought online for $136 free shipping. In every case, I didn't notice the degradation until after the new stuff.

I had my brake light come on and found the parking brake lever didn't fully return. A shot of WD40 fixed that.

Beyond that, I suggest you chase down any and all codes and correct if only to eliminate possibilities. Jumping two of the OBD1 contacts will flash stored codes via the SES light and charts are easy to find on line. Car accidents are much more costly and painful.

Good luck and keep us posted.
