1999 volvo s80 no start

Searched many threads of no start issues with no luck. My problem started when I left one night from work. Car was running fine, but spedo and tach read 0. Check eng, ABS, SC and brake lights were on. Got home shut off car and restarted ran real rough. Shutt off and decided to come back after dinner. Car would not crank at all. Ignition Antenna light stayed on and ended up Killin battery over the week, while I waited for a new ignition switch. Replaced ign switch and recharged battery. Still nothing. When turned to normally crank only the check eng light comes on. No other instrument lights. Electric door locks, windows or sun roof do not work either. Radio and air work. Front Driver and passenger door jam lights stay on as well now, but the ignition ant light does not anymore. Help what is wrong, where to gonext.

You should check the car with Vida/dice. It could be the cem that is faulty and not communicating the immobilizer codes to the ecm and vice versa. But without a high level Volvo capable scan tool, it's tough to tell.

So hooked up the vaida/dice. Would not show power or Ignition. It would also run through the test for a few minutes. But when it would end the test it would have no codes or anything. You could not click or check on any of the control modules. The dice does work as it was hooked up to another car afterwards. Power wise I do have lights, radio air blower. Everything on the doors, sub roof inop as well as car does not turnover at all. There is a sound of a click from the engine, but that's it. Battery is good. And I have good voltage coming from the positive terminal in the engine compartment.

IIRC, the entrance to the car's CAN bus is through the CEM. If that module has failed, you will be unable to start the car.

I'm going to see if I can find a diagram of the power supply to the CEM. It's possible it's just the fuse to the CEM killing the CAN bus and preventing the start.

It looks like 11C/7 which is fuse 7 in the passenger compartment fuse panel.

So tried #7 fuse by the drivers door and still nothing. Checked all those fuses to just in case and nothing. Something else I noticed just now is that the blinkers aren't working either. I think the only things I am getting power to is courtesy lights, door lights, radio and ac blower. Only dash light that comes is the check engine light. I do here clicking coming from the front of motor, not the starter. I am getting power to the starter, The main power wire. But the small one Going to the solenoid nothing. Any other insight would be great. Thanks

I did check as well I have power across fuse 7 as well, as well as the rest in that fuse box.

So the vida/dice setup I used is working on other cars. So not sure why it is not communicating with my car, it did a month ago. Another question is when does the antenna ring light up? It isn't coming on at all anymore. It did before when I pulled the ignition switch, waited for the new one, stayed on and drained the battery cause it didn't shut off. Now it won't even illuminate. Related ?

I had a similar issue. It ended up being the CEM. I had a forum post about it with more details here.

Yes it has been awhile since I have touched my no starting, non cranking, missing power 1999 S80. Between the US Navy and family she has had to be sidelined for awhile. Now I am trying to put some life back into her. I have searched the site and the internet and unfortunately a lot of similar but they are different answers here is what I have. Driving home from work and car was driving fine went over a speed bump slowly(which is where I think it started) and speedometer and tach went to zero. A variety of lights all came on. AC started blowing hot air. My DIM message window doesn't work so I had messages I there. The odometer worked. But car was driving fine, So I drove home with no problems at all. I got home and shut car off and tried to restart. I tried to turn over and clunked a little and nothing. Sounded like something in the transmission was moving, but not anymore. The key antenna light stayed on at first but doesn't even come on now, driver and front passenger door jam lights stay on no matter if open or closed(back doors are off). Head lights and brake lights on with no control over them. All the door controls on all 4 doors don't work. The only thing that happens on the dash is a Check engine light and that's it no matter key position and A slight click coming from the ETM followed by a hum when turned to start position. The only things I have control over right now are the radio, heater blower and the upper center lights above the rear view mirror, but they sometimes don't work.
So hear is what I have checked. Currently the alarm siren is out. Battery was low but not drained. But I left it out, everything I have read so it should really only affect the sunroof operation. Should I reconnect? I just don't want to replace parts that aren't needed. Don't want to dump a lot into the car really. I was working on the drivers door window and had the door module out as well as the passenger door module. Could those be a problem. Can I read either out? Those are all back installed and plugged in.

Battery is good and new with good voltage
Voltage to positive post in the engine compartment good
Good voltage to battery post on starter
Good power coming across all fuses in eng fuse box, driver door fuse box and the one in the trunk
I swapped the engine management relay with the starter relay with no change at all
I hooked up a code reader and it doesn't read car, also tried a friends VIDAS/DICE which worked before but didn't this time. Is there something I can check for that?
I also checked for power off of the ignition switch as per the wiring diagram and have power off of all 5 wires as per key position dictates.
Seems there is no power to the DIM at all except the Check engine light.
Looked at the CEM and doesn't seem to have had water intrusion, doesn't smell burnt but I didn't totally pull it out of the housing just the metal bracket.

Is there anything else that I can trouble shoot down to before I have to try a DIM, ABS module, CEM or ECU, which neither I want change as I said before don't want to just throw parts at it. Thanks for the help in advance.
