I have this car with Blind spot message, i scan the system but failed to get any info relating to this, checking on the scan tool among volvo multi controllers list, there is no controller name BLIS or blind spot module...

this car come with camera fitted to the driving mirror, now when i scan all controllers all things were okay except PDM which has rear right window failure, please i want to know how to solve this problem in other to get the message off, i look on wiring schematics but there is no related info about it, so please help me which module has this incorporate blind spot and what must i check out for... because the panel or cluster has this message display continuously

The cameras in the mirrors works through the relavent door module .. i guess your code reader cant read them .. most likely fault is the heater on the camera lenses . if you leave the ignition on for 5 or 10 minutes you should feel the lenses heat up ..

Now the scan tool i have is Launch master x431, which reads all the controllers but i cannot find the blind spot module, could it be that there is a failure to that module or could it be that the car did not come with that module or what at all need to be done, how does the blind spot works,

anyone with wiring schematic for his system

Read Clan's post again - the BLIS system works through the door module.

There is no Blind spot module .. Any fault codes will be in one of the door modules or perhaps the CEM .. Are the lenses warming up ?

this re the codes in the pdm, and the camera is not warming up

PDM-B1B7087
PDM-B1B7086
PDM-B1B7083

PDM-B117C07

upon this code all, the rear right windows rolls up and down by using the DDM or the RDM controller.

so can this be the reason why the Blind spot is not working and the message on the DIM displaying blind spot need service

Getting somewhere now , so this launch thing doesnt tell you what the codes are? Pretty useless :-)


The last code indicates a problem with the digital signal to the left rear door controller from the left front door controller

The other 3 indicate a problem with the digital signal from the left door module to the left BLIS camera ...

This network signal goes from the door module to the BLIS camera AND the rear door module so that is where your fault is , The wire is green with a white stripe ...

YOu don't seem aware that there is a BLIS camera in BOTH door mirrors ..

when you turn the ignition on and start up the BLIS orange lights should flash about 3 times to show no faults are present .

are you going to do some fault tracing or get a new door module and hope for the best?
