Is anyone aware of an OBD command that allows for scheduling multiple PID requests (instead of requesting them one at a time)?
I have seen an example but I can't find any support for it. It's possible that it's a GM specific command.
Here's the example (it's only one step of what appears to be many to complete the transaction), any help will be appreciated!:
REQUEST : 07 E0 06 2C FE 00 0C 00 0D 00
The request broken down is:
• 07 E0 = ECU CAN ID
• 06 = length of PID request
• 2C = Dynamic PID Message Scheduling
• FE = ID for this DPID
• 00 0C = Engine Speed (RPM)
• 00 0D = Vehicle Speed (kmh)
