BROADCAST RESET
Device behavior when a Broadcast Reset Command is received shall be the same as the behavior when a Targeted Reset Command is received. 5.7.4.1Tx by Master LIN ID$3C

Response
There shall be no positive or negative response to this command. Positive acknowledgment of this message can be ascertained via the reset bit in the J2602 Status Byte. 5.8 5.8.1 Message Format CHECKSUM (REF. SECTION 2.1.5, LIN 2.0 PROTOCOL SPECIFICATION)
The enhanced checksum method shall be used for all protected identifiers except for those in the range of$3C to$3F. 5.8.2 SIGNAL CONSISTENCY (REF. SECTION 1.2, LIN 2.0 PROTOCOL SPECIFICATION)
The requirement that all"scalar signal writing or reading must be atomic" is not externally verifiable in all LIN implementations. Consequently this requirement is a guideline. NOTE—Since there is a very close coupling between the J2602 Error signal and the APPINFO4 signal, implementers of J2602 slave nodes are encouraged to make every effort to publish these two status signals”
with consistency”, so that any/all error signaling between the Slave and the Master can be interpreted properly.
