Note. Check the battery condition (see BATTERY TEST ) and the charging system (see CHARGING SYSTEM INDICATOR CIRCUIT TROUBLESHOOTING ). If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN system diagnosis test mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).

Turn the ignition switch to LOCK (0), and then ON (II).
Do the self-diagnostic with the climate control unit (see «HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITHOUT THE HDS»(/acura/rdx/i-2006-2009/remont/automatic-hvac-system/#hvac__how-to-use-the-self-diagnostic-function) ).
Check for DTCs. Is DTC indicator G indicated? YES - The climate control unit is faulty, replace the climate control unit (see «CLIMATE CONTROL UNIT REMOVAL/INSTALLATION»(/acura/rdx/i-2006-2009/remont/automatic-hvac-system/#hvac) ). NO - Intermittent failure, the climate control unit is OK at this time.
