05 V70 P2 multiple fuse box location, troubleshooting Topic is solved

[daparish]

volvo v70 2005. had to have vehicle towed after 2 flat tires on freeway, after tires installed got car back started and drivable, but no power windows function (front both sides).
no functions from drivers door control panel or passenger panel .
no central locking function from door control. No mirror control.
also manually operating door lock does not activate solenoid (no click).rears ok. ambient temp display "--". climate system blower fan does not operate, but indicator lights are operatin
drivers power seat controls do not operate.
drivers window stuck in down. sun roof is operational. passenger side door switches (windows, lock) non functional. all were working before this.

Vida gives CCM-00A1 blower signal missing, CEM-1A53 DDM signal missing CEM-1A53 PDM signal missing. Hard
to believe all 3 modules went bad at the same instant (when towed for 10 mins). All were working correctly immed
before tow. Also why driver seat and ambient air temp non functional (no codes for those)?

VIDA codes
CCM-00A1 blower sig missing
CEM-1A53 DDM signal missing
CEM-1A53 PDM signal missing

Checked fuses in cabin pillar dash side panel. Fuses good but no 12v at fuse socket.

So, after checking the wiring diagram, found a listing for the "cargo area" fuse panel next to battery,
location 11E in fuse list. part num for this fuse panel is 9162321,
Now this is NOT the fuse panel in the side panel of the cargo area, its under the floor next to the battery.
In fact you have to remove the battery to even see it. This fuse panel has mostly 50 amp fuses that are bolted
in place. Part # is 9162326 for the 50 amp fuse.
In this case I checked fuse 11E/6 which is 50amp and supplies power to fuse panel 11C/ fuses 1 through 6 (bingo - all the circuits not functioning).
It was open circuit but visually looked good. Replaced this fuse and all came back to life, problem thankfully solved.
(local Volvo dealerships didnt stock it (special order) so I substituted EZGO 50 amp charger fuse 28106G01, which is the same
part and was in stock at local EZGO parts dealer).

Now the Volvo service place I took it to for the VIDA readout charged $130 for just that (readout). There recommendation was to replace the DDM, cost $500 or so, plus reprogramming and service costs would probably be over $1000 and there was "no guarantee" it would fix the problem.
(clearly it wouldnt after what I found out). presumably they would likely want to replace the CEM after the DDM didnt fix it.

Now I could not find anything on the web that even discusses problems with the 11E fuse panel (or checking these fuses). So this was all done from
the wiring diagram and basic electrical testing with a meter.

I am posting this because someone else may have a similar problem and can benefit from my experience.

This model V70 has at least 6 fuse panels (if you consider the engine bay is double layer), but not all of them
are discussed in the forums. I wish the ECM/TCM cooling was as over engineered as the fuses are.
Now if only VIDA could put 2 and 2 together to figure out in reverse what fuse to check when certain module
combinations are out.

Moral of the story is if there are multiple "no signal" issues at once, its useful to know that the 11C fuse panel is fed in groups by the 11E panel.

Way to go!

Attaching picture of the fuse panel, showing battery tray and removed bad fuse.

Good detective work there, that fuse panel looks more like a buss bar on a boat.

Great solution post. I have exact issues with 2005 S60 T5, I hope similiar 50 amp fuse panel exists on my vehicle... documentation of panel is nowhere to be found. Thank you for sharing.

turns our to have been a corroded contact from fuse box to ground; problem solved. I would have bet the ranch it was one of the 60 amp fuses on bus bar! oh well.

Now if all the trouble posts could end this quickly /well
Good post.
