so i got the C0035 Front LH circuit malfunction code (probably about 7 months ago, but just pulled the code). I followed the manual and the WSS reads ~1kohm at the sensor and from connector C1 (pins 20,21) from the EBCM. Continuity from every cable harness from the sensor to C1. i put the car in run, engine off, and got <1V from 20 to gnd and 21 to gnd.

The manual says the EBCM is bad, anyone run into this? How does an entire module go bad? A sensor i can understand, but a computer?

the manual you referring to is the GM service one..? if so it could possibly be the EBCM they can develop internal faults..try a junkyard one for function..goodluck

Yea i was refering to the gm 3 vol service manual

couple of newbie questions here: how can i tell if i have Traction control? i'm a 98 5spd 3.8L, no switch for traction control, but i do have a low traction amber warning light.

Also how can i tell what ch EBCM i have? Thanks!

After reading the above links i'm a little confused. Will an EBCM from a 99-02 Camaro 3.8 w/o TC work on my car, or do i need to find one from 98?

OK found a BPMV and EBCM. Should i install it as an assembly? or just the EBCM? if just the ebcm does anyone know where i can buy a seal, screws, and the spings?
