Hello!
I am desperate for help. I would like to offer a small award to anyone who can offer help that leads to a solution. This award will likely be around $100 and will be offered by paypal or bitcoin if the helper is willing. This is not a guarantee of any award, just a willingness to offer it. I will check this VERY frequently until the problem is solved and I'm very happy to answer questions or provide more informaiton.
I have a 2004 Volvo S60 that I have owned since 2009 or so. When I bought the car the original owner warned me that it was possessed, but I felt brave enough to take the car anyway.
The problem can be best simplified as follows: When the ambient temperature is above 70F degrees and the relative humidity is high the instrument cluster "clicks" out, the ABS & Brake lights comes on, the status menu reads "Brake Failure Stop Immediately", the Temperature gauge, Speedometer, and tachometer all report 0. If this occurs while driving at interstate speeds it is sometimes accompanied by a violent jerk that feels as if I've run over a brick.
We live in Tennessee, our warm summer months are from April to October - this condition has ONLY occurred during these months.
I have learned that failures during heat and humidity may signal a problem with a relay - I have replaced several relays, specifically PN 9441158 at the CEM Module in the trunk for Power Supply Relay A & B to the ABS module.
I sent my ABS module to Xemodex last year and they sent back a different ABS module with their custom upgrade, but nothing changed. I also purchased an ABS module from ebay and had Darrell Waltrip Volvo (great shop!) flash the firmware with no change.
Darrell Waltrip Volvo in Nashville has been my preferred service center but they haven't been able to identify or solve the problem either. In 2012 they kept the car for several weeks during the summer and observed the problem. They eventually replaced the housing for the electronic module in the front right of the car, but this didn't solve the problem either (this was awhile ago and I may be somewhat mistaken about what work they performed).
I own a Diagnostic System PPC by BSR code reader and I have collected the codes that were in the car this morning:
TCM E000 Control module communication
TCM E003 Configuration Fault
CEM 1A61 Communication with TCM
CEM E000 Communication control module
PDM 0040 Outside temperature sensor
PDM 0030 NOT A RECOGNIZED CODE
ECM 0030 Temperature sensor of control unit
PDM 0032 NOT A RECOGNIZED CODE
Here are some videos that may be helpful:
This video is from 2010 when I first became determined to understand the problem. It isn't very descriptive, but you can see around second :24 where the car jerks as if I hit a brick.
This video is from yesterday, it is about 10 minutes as I describe what I'm seeing as I try to get the car going again so I can get home. Some of my descriptions are a little confused/inaccurate as I'm trying to drive, video, and talk. (Video gets boring when I start driving - nothing except talking about details)
This image shows the most common manifestation of this problem. The car was travelling on the interstate while the picture was taken:
Last thing - this information fails to capture the "clicking" aspect. When the event occurs while driving, it is usually accompanied by audible clicking that appears to originate from the instrument cluster area. I am beginning to wonder if the relays below the instrument panel could be related.
