It is weird , I installed 2014D today, but I still have not see CCM calibration option. From youtube, I saw other people have 6 options on 'Advance' tab, but I only have 4. Is it normal for 2003 XC90?

There is more then one Gn-R at the fuse box. One going to the starter relay from the CEM and one from the starter relay to the starter. Pull the starter relay at the fuse box. Clean the connections. If that does not work, swap the starter relay with one of the others that is the same. This might di...

I did check based on xc90 wiring document, ignition switch is fine (output voltage is 14.2), but fuse box Gn-R voltage is 0, sounds CEM or ECM problem.

Can Vida Disc reset/reload CEM ? If yes, I would like to pay $60 on ebay to get it.

Your Immobilizer Antenna maybe on the fritz. It may not be reading the key security codes reliably. You might try holding the plastic part of one key right next to the antenna ring as you turn with the other key. Today, I measure the voltage on ignition switch output Y-W cable, which is connected t...

However there are somethings that could be a common root cause to both. Ignition switch is one. Before you go after the Ignition switc...

Thanks, any idea on how to check central electronic module?

Hi, Ok, I will try it next time, but it looks like not wire connection problem. This morning, I failed to start on first time, then tried second time immediately with push very hard of key, it started. We had something like this not to long ago. But the guy had trouble following instructions and nev...

Hello everyone, I need your advice. 2003 XC90 T6 w/ 10.5K miles, it has no click, no cranking, no start issue intermittently. Dash lights come out, AC not start, headlight is on for 1 seconds. No any alerts. Looks like no electric power supply to starter. I have replaced started and battery, I also ...
