Hi

2134 it's about Voltage Problem... Batterie near death? load it full an watch about this code on next time...

2131 Breaklight switch... do you step the breakpedal before blink out the codes?

3221 It's the Switch for the reverse gear - or the wiring on it... and it's the most suspect part... change it...
