Puffwagon Posted April 19 Share Posted April 19 What's up everybody?! My territory wont upshift via the shifter in manual mode. It will downshift however and will go in and out of performance mode. It is an AWD 6 speed, the box is a zf6 hp26 hybrid. All other automatic functions work fine. There is a circuit board attached to the shifter, the shifter has a magnet in it and the magnet passes over sensors to tell it when it goes from park to r, to n, to d and over to performance mode. In the performance mode side there are 2 sensors, one to upshift and one to down shift, obviously when you move the shifter it triggers a sensor and it shifts. If I earth the performance pin it will light up performance mode on the dash and if I earth the downshift pin at the same time it will go into first. If I earth the upshift pin nothing happens. The wiring fucks off through the floor under the centre console and I suppose it goes up to the pcm or maybe straight to the tcm? I'm wondering where is the best place to check for continuity? I've cleaned the fark out of the zf plug etc. It was working when I bought the car and stopped working after I flashed the trans. It now has a different trans in there, I've tried a different shifter circuit board and I've looked for anything obvious in the tune that did it. I can't put the box back to stock as it is from a different car and will go into limp mode if I flash the stock TCM file into it. I think it is a coincidence about the flashing thing but worth a mention in case anyone has come across it before. There's a high 5 and a 6 pack of beer in the post for whoever nails it lol. Thanks for the help 😁 Quote Link to comment Share on other sites More sharing options...
Bill Posted April 19 Share Posted April 19 Check continuity between tip+ at the shifter & pin 5 at the TCM connector. Tip- is pin4. Check the pin isn't pushed back in the ZF connector & the TCM pin isn't damaged. Wiring damage near the connector is possible too. Sorry for the poor quality wiring diagram. I had to zoom out further than I wanted before being able to snip the image. 1 Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted April 20 Author Share Posted April 20 Thanks mate, I'll check it later when I get a chance. 1 Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted April 20 Author Share Posted April 20 I had a check, there is continuity on pin 4 but nothing on pin 5. I guess I'll take the centre console out and pull the carpet back to find exactly where the loom goes through the floor. Asking a perhaps obvious question, does the shifter wiring go straight to the trans? Quote Link to comment Share on other sites More sharing options...

I guess I'll take the centre console out and pull the carpet back to find exactly where the loom goes through the floor. Asking a perhaps obvious question, does the shifter wiring go straight to the trans? The wiring from the ZF6 connector goes to the C20 connector which is the large main engine wiring loom connector, passenger side of the engine. It's not uncommon to find broken wires here or near the ZF connector. Image is FG but the wiring location is the same. Wire colours may differ From the C20 connector, it goes to a connector in the passenger footwell. It's also not uncommon to find this section of wiring loom has rubbed through on the aluminium AC pipe near the passenger shock tower. If water has made it into these connectors, there'll be corrosion on the connector pins. It's rare to find any broken wires in the cab, but it's possible. The territory manual I have for SY doesn't have wiring diagrams for the ZF6, only BTR so is not useful. The FG manual shows the ute wiring loom goes directly from the passenger footwell to the shifter whereas the sedan shows an additional connector beside the passenger seat that may be accessible if the foot scuff plate is removed. I wouldn't go searching for this one unless there was an issue between the footwell & shifter. I've run out of time to get more images, but it gives you a starting point. 1 Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted April 21 Author Share Posted April 21 There is continuity between the zf plug and the main connector on the upshift wire. I guess I'll be looking between the shifter and the other side of the connector. Quote Link to comment Share on other sites More sharing options...
Puffwagon Posted April 21 Author Share Posted April 21 I followed the wiring from the shifter into the passenger footwell and there is continuity after the grey plug that goes into the main wiring harnesses. There is no continuity from the interior plug into the main wiring harness plug under the bonnet. I ran some speaker wire from the plug in the footwell into the plug under the bonnet and it upshifts. Obviously the break is somewhere under the dash or in the engine bay. I should have investigated this while the engine was out 2 weeks ago but I didn't. I'm just going to run another piece of wire for now, be farked digging into the wiring when there is so much stuff in the way. Thanks for the help Bill, pm me your address if you want some beer. 1 Quote Link to comment Share on other sites More sharing options...
Bill Posted April 21 Share Posted April 21 Not a problem mate & whilst I don't mind a beer, I don't expect anything. Have a beer for me 2 Quote Link to comment Share on other sites More sharing options...
