1998 V70: Remote not working and no alarm

Post by **Goupil** » 17 May 2019, 10:41

Hi,

I bought my V70 with a pair of non working remote.
As per the seller, one just needed a new battery while the other wasn't programmed, but I couldn't get any to work

Car was built in late 97, and it has the red light on the dash. I've never seen it being lit.

Central locking works fine and I fixed the door lock switches a few weeks ago.

It had an aftermarket alarm, which seemed inactive since I didn't have any of the remotes for it. The alarm featured a LED (K6 and K8 on the schematics), which flashed when I did the remote programming procedure, but the remote still wasn't working.

Thinking the aftermarket alarm could have been the issue, I removed it (what a great day of fun this was

). It did not make a difference, and I'm not sure what to try next

Could the alarm module be bad and keep the remote from working

Or maybe the stock alarm was deactivated (if even possible) when the aftermarket one was installed ?

Newbie here.

Hy. How did you remove the aftermarket alarm ? You post a wiring. Did you find cables on your own installation ? There must be another wiring board more precise, no ?

No factory wires were cut, the aftermarket alarm ones where just soldered right onto them.
I just cut them off, soldered the stock ones if needed and insulated everything.

This schematic is the only one I could find, there's not much with the alarm being at least 10yo from what I could find.

I just found the massive pdf of Volvo wiring diagram for the 1998 x70, i'm off to a good read !
