last few days, my 6 years old car start giving me weird problem which rarely heard from any wajarian.....
it was the reverse sensor and reverse lights....now the reverse sensor and reverse light seems doesn't activated whenever i engage reverse gear....i only realised that when i bang into parking wall inside basement parking (reverse parking)...my sensor doesn't produced any sound which made me felt the wall still far away, then suddenly bang!!!! i was like SH*T!!!!

....luckily i wasn't 'bang' into a car and it just like a minor 'bang' only

....
at first thought i suspect my reverse sensor malfunction already or going weirdo (coz i just finished washing the car before that)...but then i noticed my reverse light also not turned on when i engaged reverse gear

...after several attempts of re-engaging my reverse gear then the reverse light & sensor working as usual....
now each time before i reverse, i have to ensure the lights & sensor is activated....if not, i'll keep on re-engaging the reverse gear until the reverse light & sensor working...it's annoying, i cannot afford to do that in emergency situation or rushing time....it's also dangerous if i reverse without the reverse light coz anyone behind me may not aware of my actions.....
my car is manual 4G18 engine...anybody happen to experienced the same thing and have DIY solution???

i don't wanna bluntly head to EON on Proton Edar which may end up my gear box being dissemble to diagnose the problem and get con

Just bring your car to accessories shop , it's just the reverse wiring/thingy malfunction. Happen to me once for my wira.
Less than fourty bucks if not mistaken.
