6.2 ISO 14230-4 (Fast Init)
After switching to the ISO 14230-4 protocol with fast init option, the PIM will
print the following status message:
It will not respond to any requests until the bus is initialized. After a successful
initialization sequence, the PIM will print:
At this point, the virtual ECUs will start responding to OBD requests. However,
if five seconds pass without a supported request (or a keep-alive message)
being received, the ECUs will time out and the PIM will go back to waiting for
initialization:
6.3 SAE J1850 and ISO 15765-4
Protocols 1, 2, and 5 do not require initialization. Once the PIM reboots after
the set protocol command and prints the configuration summary, it will
immediately start listening to, and responding to OBD requests.
6.4 Monitoring OBD Traffic
By default, each PIM prints incoming and outgoing OBD messages including
the message headers, but without the checkbyte. Here is an example of
communication between a tester and the PIM on J1850 PWM:
Rx: 616AF1 01 00
Tx: 416B10 41 00 BE 1B 30 13
Tx: 416B18 41 00 88 18 00 10
Tx: 416B28 41 00 00 08 00 10
J1850 VPW, ISO 9141-2, and ISO 14230-4 messages follow the same format:
each message has a three byte header followed by data bytes. ISO 15765-4
