Help with trailer module installation
Posted: Fri Jul 12, 2019 6:54 am
Hi everyone - hoping some of you can help me with the following problem.
I have a 2014 Ranger Wildtrak (2015 model year, built August 2014). I purchased it new when I lived in Malaysia (it was built in Thailand, not South Africa like the European Rangers are), and have imported it into the UK. I have fitted a tow bar and a wiring kit purchased from PF Jones. I installed the wiring kit carefully following all instructions, used my new Windows 10 Forscan USB Adaptor to re-programme the computer, and plugged my caravan into my newly fitted 13 pin plug on the tow bar. Unfortunately the caravan’s LED lights don’t work at all (nothing when connected to my truck, but Ok when connected to other cars). On further investigation I discovered that the trailer module from PF Jones (it is LED trailer light compatible) that I installed under the passenger seat was showing a constant red LED light. The manufacturer (Conwys) has told me this means either that the earth to the module is not connected properly or that the module is not receiving the correct CAN bus signals. I was able to confirm that the earth is connected properly and that the two CAN bus wires going into the module carried around 2.5V meaning (according to Conwys) that everything should work - but it doesn’t. They even sent me a replacement module and wiring, but those have made no difference. It has been suggested that being an import, the Can bus frequency might be different (newer) that PX1 European Rangers. A trailer module to fit 2016 and on Rangers is being sent - but I am doubtful this will work (thoughts?).
When I used Forscan to programme the truck’s computer, I was only able to make changes to the primary module. I was not able to work out how to change the secondary module. I made changes to the following four items in BCMii Central Configuration (Main)
• Rear foglight tow function
• Trailer module
• Towbar
• Trailer Stability Assist (the wiring instructions didn’t ask me to change this but I did - should I have?)
Although everyone has told me that the re-programming should have no effect on the trailer module making the trailer lights work, I have since changed the settings back to their original, but that hasn’t helped either.
The other thing I have noticed is that the number of DTCs detected is increasing (see attachment below). I was expecting there to be some associated with the ABS as during the import process the rear axle was driven at high speed on a roller whilst the front axle was stationary and this resulted in the ABS light coming on. The tester told me to expect fault codes as a result. However I am unsure about the other fault codes that have now appeared - is it something to do with the changes I made and/or fitting the trailer module and might any of them be the reason for the trailer module not working properly?
Any hints, tips, thoughts on any of the above would be very welcome.
Cheers
