A20DTH (LBS) ECM $AE Commands (Device Control)

 

Use at caution! (Use at your own risk) some of activation command requires specific condition. may damage engine/related system when improper use.

send '3E' (tester present) signal periodically if you want to keep device control. (some of device control command may have its restriction (time/count limit, condition)

@JBL_1989 Thanks for the info! By the way, the command AE 28 80 00 00 00 00 is ECU hard reset. Usually it is sent at the end of reflashing procedure.

Nice work. Where did you find the list of CPIDs ?
