I just had 'barrel' ask me to clarify the Police Mode setting.

The Offsets for writing to the ODO are:

00 = ODO
01 = Body/Fuel - and maybe more. The data in here is very cryptic and we've been working for awhile to decode it without much luck.
02 = Police Mode 'Offset' for fine tuning the digital speedo (usually 00)
03 = A bunch of settings. I'll focus on this.

To write by offset remember that it's 3B. So go back to the original post for setting up an ELM to write to the IC.

For offset 03, low series clusters use 1 byte, and high series clusters are 2 bytes.

Byte 1:

Bit0 = Seatbelt Reminder
Bit1 = TCM Jewel
Bit2 = Police Mode
Bit3 = May be the Shift Alert - but not sure yet

Bute 2:

Bit0 = HDC Jewel
Bit1 = DSC Jewel.

So if you have a low series cluster, when you read offset 03 you type '2103' and you should see something like:
727 03 61 03 03

It''s the last byte we're interested in here.

A high series cluster with DSC on and TC off may look like:
727 04 61 03 01 0E

It's the last 2 bytes we're interested in.

03 HEX = 11 Binary (Or 00000011).
01 HEX = 1 Binary (0000001), 0E HEX = 1110 Binary (00001110)

(Note: I don't yet know what the bits 2 and 3 do yet in the high series Byte. )

Bit 0 is LSB - or Least Significant Bit - and is the rightmost bit. To enable Police Mode you need bit 2 set to 1, so thats 00000111, or 07 Hex. So you write this as:

3B0307 for low or
3B03050E for high

Hope this helps.

Hi mate sorry to bother you but i am having a hard time getting head around this i have a BA falcon RTV ute and have managed to get police mode on with TC jewel on also can turn police mode off but for life of me cant get TC jewel to turn off either have a high series cluster trying to figure command to turn both TC jewel off and police mode,

Yeah I have so far written 2 programs, B Series Cluster Tool which is an ELM compatible Instrument Cluster tool that allows you to setup all the options via the can bus, also has functions to check speedo/tacho calibration etc.

My other program is the B Series Cluster EEPROM Tool, which allows you to edit a Cluster EEPROM file (which you would need to get from the on board EEPROM). This allows you to do alot more as in set different speedo ranges, change cluster to a High series and also change the odometer etc.

Both of these are in final testing stages now.

I am looking at developing at least another 2 or 3 programs, B Series PCM Tool and BEM Tool and a B Series DTC Tool. The DTC tool will be released on here when its complete.
