Notes:
1. Several Programmable Parameters describe options in terms of bits. For all of them, b7 is the msb, and b0
is the lsb. As an example, the PP 2C default value of E0 can be shown as 11100000 in binary. This number
has has b7, b6 and b5 set to 1’s, while b4 to b0 are all 0’s.
2. When b4 of the CAN options PPs is set, the CAN baud rate will be increased by a factor of 8/7. For example,
if you set PP 2C b4 to 1, and PP 2D to 06, the actual baud rate will be 83.3 x 8/7 = 95.2 kbps. If you are
unsure of your setting, the display protocol (AT DP) command may be used to display the baud rate.
3. The PPS command makes provisions for PP numbers 00 to 37, but not all have been assigned functions. If a
PP number is not shown in this table, then it does not currently have a function and it will not affect the
operation of the ELM329.
