    Ok, I've fixed the neutral safety switch, feed 12 volts to th correct pin for brake feed. Changed tune, still will not let me do crank relearn. What is the scan tool looking for, I'll start there??

    How do the guys running a stand alone harness get this done?

    Vehicle needs to be within a certain temp range. Must be in Park, and see Foot applied on the brake signal. No DTC's pending.

    That's all I can recall at the moment.

    An old thread, but very relevant. Trying to do a crank relearn with no luck. LS1B 2001 Camaro manual tune Operating System 12202088 on a 24x conversion Ramjet 350 . I have both the Brake and clutch switches. C1 32 Normally Closed to ground, C1 33 NC to 12v. Using Ver 8 Scan and Tune, with a V3 device. Thinking about trying Ver 7.5 Scan if that will even work with my V3. It starts, but runs rough. Throwing P0200 injector codes, P0480/P0481 fan codes along with the P1336 CKP relearn code. Clear them before relearn, still nothing. I think ill try grounding C1 34 to fake park/neutral even though it is a manual tune. Any thoughts or suggestions??? Thanks!

    I'll have to look at the GM service manual to see all the required conditions.

    That would be great. I have tried all I could think of. made sure there were no current faults, foot brake on, clutch in, grounding C1 34 P/N. still no go. I just set it to No MIL for now to deal with later. P0327 KS is kicking my ass now!
