Quoted from dothedoo:During self-test, do any coils fire more than once during one cycle? If so, check connector J4 on the MPU and J4 on the SDB for broken pins inside the housings.
This. Also make sure the coils fire in proper order in test, according to the manual. If some are missing or out of order, rebuild both J4 female connectors.
