Clearing Codes
Disconnecting battery WILL NOT erase codes. Each code stored in CIS-E control unit and MAS unit memory must be erased individually. After malfunction code is displayed, wait 2 seconds then press START button for at least 6-10 seconds. LED will blink once, or impulse readout will display "=1", indicating code is erased. Continue this sequence until all codes are erased and only "=1" is displayed. Disconnect test equipment.
