Are any DTCs indicated?

NO - Go to step 10.
7. Record all DTCs and sort them.
8. Troubleshoot the DTCs in this order:
-
Battery voltage DTCs
-
Internal error DTCs

Loss of communication DTCs (begin with the lowest number first; for example, if B1008 and B1011 are retrieved, troubleshoot B1008 first)
-
Signal error DTCs
9. Clear the DTCs by pressing and holding the select/reset button for about 13 seconds. You will hear a beep to confirm the code have been cleared.

NOTE: If the MFCS connector is disconnected for too short or too long of a time, or the ignition switch is turned OFF, the system will return to
Test Mode 1.
