Error codes# 6 + 49

Newbie here? I bought 2009 E2 with 12,00 miles in Nov 19. I have all three lights flashings (R-DL-DH) and no click from contactor going forward with error code #6. When I go to Rev lights only show R, beeping and I get click from contactor, starts to move and goes to error# 49. I’ve replaced Forward-Reverse
switch, no change? Any help would be appreciated. Thanks, HLF

Check direction wires at controller. P4 and P5. One but not both need to be near battery volts.
Throttle switch P7 needs to be <1.4v at zero throttle.

#49 is something else.

Thanks for your help! Turned out to be a bad controller.
