0x42 OBC Remote Control

Cluster 0x80 → GT 0x3b
GT 0x3b → Cluster 0x80

This command is used to configure which of the 12 available functions are recalled on the high (IKE) cluster character display.

No. Function Display
1. Clock "TIME 2:40PM"
2. Date "DATE 12/02/2020"
3. Consump. 1 "CONS1 10.1 L/100"
4. Consump. 2 "CONS2 13.2 L/100"
5. Range "RANGE 22 KM"
6. Distance "DIST 17 KM"
7. Arrival "ARRIVAL 3:22PM"
8. Limit "LIMIT 60 KM/H"
9. Avg. Speed "SPEED 59.9 KM/H"
10. Timer (Stopwatch) "STOPW 2:02 MIN"
11. Auxiliary Timer 1 "*TIMER1 11:03 PM"
12. Auxiliary Timer 2 " TIMER2 2:54 AM"

It has two use cases which work in sequence:

  1. edit the configuration via the GT/BMBT (Cluster 0x80 → GT 0x3b)
  2. memorise the configuration to the IKE (GT 0x3b → Cluster 0x80)

Examples

80 0F 3B 42 10 0F 0E FF FF FF FF FF FF FF FF FF 18

Function 7 6 1 Bitfield
Function 8 7 1 Bitfield
Function 9 8 1 Bitfield
Function 10 9 1 Bitfield
Function 11 10 1 Bitfield

Use Cases

Edit Configuration

Cluster 0x80 → GT 0x3b

IKE will send the current configuration to GT, which in turn will load the "Remote Control" screen with applicable functions preselected.

Note: the options Delete all and Memorise are handled by the GT, so neither will return 0x31 like radio or telephone menus.

Remote Control Programming

Example

# Load "Remote Control" configuration (Distance, Limit)
80 0F 3B 42 07 09 FF FF FF FF FF FF FF FF FF FF F8
Parameter Func. Func. F. F. F. F. F. F. F. F. F. F.
Data 07 09 FF FF FF FF FF FF FF FF FF FF
Function Distance Limit -- -- -- -- -- -- -- -- -- --

Memorise Configuration

GT 0x3b → Cluster 0x80

GT will send the selected functions to IKE, at which point the configuration is updated.

The order of the functions will reflect the sequence in which they were selected. This will also be the order in which they are recalled for display.

Example

# Memorise "Remote Control" selected functions
3B 0F 80 42 10 02 06 FF FF FF FF FF FF FF FF FF 1D
Parameter Func. Func. F. F. F. F. F. F. F. F. F. F.
