Hi All,
I’ve been a member for quite a while now, and have read most every post, but this is my first post.
I have an issue with reverse in my PC Challenger Auto. The car was purchased new in 2014 and has only 21000 klms on the clock. It isn’t a daily driver, tows a 1.56 Tonne Tare – 2.06 Tonne ATM caravan when we can get away, no big trips yet, 300 klms at most so far. The warranty expired this year. It has been serviced by Mitsubishi since new and has been reliable.
I drove the Challenger last weekend, not towing, and noticed it engaged reverse more harshly than normal. I thought little of it at the time, but when I drove it again today, the harshness was still there. The car drove normally and reversed normally, but when I was reversing out of a picnic ground, I noticed my reverse camera wasn’t operating. I drove home before looking to much into it. When I got home, I realised the reverse sensors weren’t picking anything up, and that the reverse lights were out. I checked the fuses and they were all fine. It was then I realised there was no ‘R’ in the digital display on the dash. P, N, and D show up, just no R.
I dropped the third bash plate so I could watch the selector as the gearbox was cycled through the gears and all looked fine. It is all very clean and like new underneath as the bulk of the off road use this car gets is beach and sand driving. I have a Navara dual cab that gets dirty.
The car selects reverse mechanically; it just doesn’t seem to know it’s in reverse electronically.
There are 3 things I’ve done to the car lately that may or may not have had an impact on this but are worth mentioning. I have recently reinstalled my updated Automate. I don’t think this is the issue as I have run Automate since it was available for a PC, and Lockup Mate before that. Never had an issue before and couldn’t imagine towing without it again. To be sure though I tested the car with Automate turned off and then disconnected. The reverse issue continued.
I have changed my rear springs from KCRS-23 Raised to KCRR-23HD Raised. I can’t see how this would cause the issue, but there may be wiring to the back of the car I have damaged unknowingly but doubt it. The reverse light and automatic fuses were fine though. I both checked and replaced them.
The third was to feed a twin core 8mm2 wire through the large grommet on the passenger side firewall and feed it through behind the glove box. I had the dash in this area partly disassembled to see as best I could when feeding a solid wire through first. I took a few goes to get the solid wire through. Is there anything behind the glove box that I could have disconnected, without knowing, that could cause this? I ran this cable under the passenger side kick panels to my drawers. It's not connected to anything yet, just a cable from under the bonnet to the cargo area.
Where is the reverse light switch? My next thought is to check the switch to see if it is connecting, try to connect it to see if it makes a difference.
The car did throw a P1901 code when I reconnected Automate, but that is normal, at least for mine. I find I can clear this code straight away with my UltaGauge if I have the ignition on but the car not running. It’s hard to clear with the car running. There is no check engine light on at the moment.
Any thoughts guys? Thanks for your time in advance and thanks for all the tips and advice I have read on this forum in the past few years. It’s a valuable resource for Challenger owners like me, although I can’t recall reading about a problem quite like mine.
Edit: I just put the car away and it threw a P0705 code. I cleared the code, and the problem persists.
Cheers,
Despicable.
