Service Procedure
1. Connect a battery charger DCA-8000 to the 12-volt battery.

charger is installed on a chassis or engine ground, and not the 12-volt battery negative terminal. Do not have
the vehicle plugged into high voltage battery charger during programming. This can cause incorrect module
programming. Make sure only the 12-volt battery charger is installed.
2. Reprogram the SOBDMB and SOBDMC using the latest level software level of the FDRS scan tool.
