System malfunction location	Foot-motion detection unit power supply voltage low or high input
Detection condition	• The power liftgate (PLG) control module detects the following conditions: ― Foot-motion detection unit detects that the power supply circuit voltage is the standard value or less ― Foot-motion detection unit detects that the power supply circuit voltage is the standard value or more
Fail-safe	• Stops the hands-free liftgate operation.
Possible cause	1. DTCs are stored in the following modules. ― PCM (See DTC TABLE [PCM (SKYACTIV-G)].) (See DTC TABLE [PCM (SKYACTIV-X)].) (See DTC TABLE [PCM (SKYACTIV-G 2.5T)].) ― DC-DC converter(See DTC TABLE [DCDC].) ― BECM/Mazda M Hybrid Boost battery/Mazda M Hybrid battery (See DTC TABLE [MHB].) ― Drive motor control module/Integrated starter generator (ISG) (See DTC TABLE [ISG].) ― ECM 2. Battery/lead-acid battery malfunction (Refer to [BATTERY INSPECTION] in workshop manual.) 3. Generator malfunction (except e-SKYACTIV PHEV/e-SKYACTIV EV/Mazda M Hybrid) (Refer to [GENERATOR INSPECTION] in workshop manual.) 4. Malfunction in wiring harness (including connector/terminal) between foot-motion detection unit and body ground (See CIRCUIT INSPECTION.) (See CONNECTOR INSPECTION.) 5. Malfunction in wiring harness (including connector/terminal) between battery/lead-acid battery and foot-motion detection unit (See CIRCUIT INSPECTION.) (See CONNECTOR INSPECTION.) 6. Foot-motion detection unit malfunction (Refer to [FOOT-MOTION DETECTION UNIT INSPECTION] in workshop manual.) 7. Power liftgate (PLG) control module malfunction (Refer to [POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION] in workshop manual.) 8. Body control module (BCM) malfunction (Refer to [BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION] in workshop manual.)
Repeatability verification procedure	1. Clear the DTC recorded in the memory. (See CLEARING DTC.)
