<ALL ECUS TIMED OUT>
<WAITING FOR 5 BAUD INIT>
6.2 ISO 14230-4 (Fast Init)
After switching to the ISO 14230-4 protocol with fast init option, the simulator
will print the following status message:
<WAITING FOR FAST INIT>
It will not respond to any requests until the bus is initialized. After a successful
initialization sequence, the simulator will print:
<FAST INIT: OK>
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 simulator will go back to
waiting for initialization:
<ALL ECUS TIMED OUT>
<WAITING FOR FAST INIT>
6.3 SAE J1850 and ISO 15765-4
Protocols 1, 2, and 5 do not require initialization. Once the simulator 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, the simulator 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 simulator 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
