I installed a new tune tonight and my car idled horribly and shut off. I got a DTC 1233 FPDM disabled/offline. I tried to install my old tune and it won't start can someone help me?
did you check the fuses? did you remove the fuel pump fuse while installing tune?
you have the fuse at the BAP, fuse at the box in the engine bay and fuse for the wire upgrade. also, the fuse at the engine bay box should be a 30. stock is a 20, but you put a 30 in for the BAP
Did you install the interia switch? If so jumper (bypass) it.
