Hello,

SNR: 1A400947

Have this issue with an Rc5500 that wont start up correctly.
The display lights up the battery indicator and the keypanel but wont show the model and other info in the middle when putting keyswitch in startup.
Display beeps twice and wrench symbol lights up.

The display is ok, will show rekey 109 error if not putting keyswitch all the way.

Have checked and switched out relays k1, k2 in distribution panel.

CANBUS is ok 60ohms no shortage.

have checked powersupply to all Accesses, its ok.

I get a message from the backside of access 7 through the indicator lights where it blinks 7 4 10. Have not found any info about this.

How to proceed? Any help most appreciated!
