First make sure fuse 56 in the under his fuse block is good and has power to it. Next remove the RCDLR and make sure a test light glow bright between red/white wire terminal H and a good ground on terminal S black/which wire. Next check for a toggling voltage between terminal L and ground between 0 and 7V, if it's steady at 0,7, and not fluctuating or above 7V reply back, if all check out good replace the RCDLR. Please give a positive rating. Thanks

The voltage is good , when I replaced the RCDLR the ignition can not turn on and door can not open. I used the GM MDI to program the RCDLR and when i try to program the key by TECH 2 can not program .
