can id´s 4 Gear Selector

[medolino]

Hi, does anyone happen to have the can bus ids for the jaguar or land rover gear selector, am testing whether it would be possible to make them usable for the LDU

Best regards

[medolino]

that´s what i find out

die anderen pins hab ich leider noch nicht herausgefunden

to the can bus messages, I have found the following so far

0x02c 0x00 0x00 0x09 0x00 0x00 0x00 0x00 0x00 rising the Knob
0x02c 0x00 0x00 0x10 0x00 0x00 0x00 0x00 0x00 lower the Knob
0x02c 0x00 0x00 0x00 0x40 0x00 0x00 0x00 0x00 unlock the Knob to spin
all of that, every 100ms

What model year is the part from?

Have you had it working outside the car with just sending those can bus commands?

[medolino]

the part is from a Jaguar f-pace, production year 2018, is the same as in Range Rover, yes it works outside the car

[tom91]

Very cool, but the light does not come on on the position?

Can you rotate the knob to select other positions, it should be easy to decode the feedback of that.

[medolino]

to rotate the knob, i must send every 100ms this code 0x02c 0x00 0x00 0x00 0x40 0x00 0x00 0x00 0x00, to unlock, but nothing Receives on Savvy

I've been looking at a Jaguar XK rotary gear selector which has the EPB and Start/Stop button. This will be an older unit but I must test your CAN data above to see if it responds.

Believe this is the correct pinout for my unit. What connector detail is on your unit? Could it be that it needs a signal like wake-up or P/N etc before you see any more CAN data?

I saw a few of these units and wondered if they tested all functionality but doesn't look to be. But for the basic testing they do, look to be 6 wires minimum to the connectors:

I think it's the same message for all models

I got one of those on the way so hopefully can add some info soon.

[tom91]

I got the tested.

Turns out the Yellow wire, ignition, is a switched 12V it raises and lowers the older style Jaguar knob, large connector.

[tom91]

Guess there is some form of check sum in byte 5

This is for raised and P illuminated, byte 4 is cyclising counter, message id 0x02C

Code: Select all

1E	0	2F	52	0	21	0	80
1E	1	2F	53	10	BC	0	80
1E	2	2F	54	20	6	0	80
1E	3	2F	55	30	9B	0	80
1E	4	2F	56	40	6F	0	80
1E	5	2F	57	50	F2	0	80
1E	6	2F	58	60	48	0	80
1E	7	2F	59	70	D5	0	80
1E	8	2F	60	80	BD	0	80
1E	9	2F	61	90	20	0	80
1E	10	2F	62	A0	9A	0	80
1E	11	2F	63	B0	7	0	80
1E	12	2F	64	C0	F3	0	80

1E	14	2F	66	E0	D4	0	80
1E	15	2F	67	F0	49	0	80

Also found some interesting ones with same check sum but different message info.

Code: Select all

1E	0	2F	40	80	FB	1	0
1E	0	2F	41	0	FB	2	0

[medolino]

do you have a log file, would like to analyze the whole thing

to turn the nightlight ON is id 0x244, 0xF7 0x40 0x00 0x00 0x00 0x00 0x00 0x00
OFF is id 0x244, 0x00 0x40 0x00 0x00 0x00 0x00 0x00 0x00

Here are the logs I took of it connected to the tester.

[medolino]

Many thanks for the effort, try to pick up the messages from the tester, not from the Knob, which messages come from the tester

[tom91]

only the 0x02C is the tester. Knob is the other ID.

[LRBen]

I've figured out most of the pinout for the 12 pin connector:
1. 12v main feed
2. Ign
3.
4.
5. Can H
6. Can L
7.
8.
9.
10.12v
11.
12. Gnd

On mine once I connect the ignition I get messages on the canbus and the backlight. ID 0x312 at about 20ms intervals. Canbus log attached.
Sending the messages to raise and lower the knob seems to have no effect, similar with playing back logs from Tom. But possibly due not having whatever pin 4 is attached.

[tom91]

You possibly have another version.

What build year is yours?

The Jaguar knob I have, the one with the park brake and other switches also send 0x312. I will upload the captures to the github.

I have not looked at the older knob log to figure out what ids are from my chinese tester and which are from the knob.

[LRBen]

Not sure on the year, but model number is BH42-7E453-AJ.

I did have success playing back the Gen 1 Logs with 0x312. Raises the knob, lets me rotate it, changes lights, but doesn't lower again, even playing back awake lower knob.

Edit: looks like 0x3F3 is the only message needed to unlock the knob and change the lights. 0x299, 0x2A0, 0x422 also look like they came from the tester but dont seem to do anything, with only 0x312 coming from the gear selector. It's possible they have something to do with raising and lowering the knob though.

[LRBen]

Looked through the canbus logs and figured out the rough patterns. These are the two important messages from what I can tell.

Code: Select all

Model number on mine is BW83-7E453-AC and I get the same result as you. Playing back some of the different logs raises the knob, allows it to rotate, changes light between P-R-N-D but doesn't lower the knob in any. The knob raised on the first playback and stayed there.

Haven't figured out how to get the knob back down yet either. What wires do you have to the connector? I'm thinking potentially whatever is on pin 4 is somehow important, since canbus messages alone are not enough to lower it it seems.

[tom91]

To lower the older knob, remove the ignition power.

doesn't work on the newer ones
