CUSTOMER CONCERN The tire-pressure warning system stores DTC C2126 because a transmitter ID is not received in main mode after sensor replacement. CAUSE The confirmed repair identified a failed replacement TPMS sensor and an incomplete transmitter-ID registration. CORRECTION Remove and replace the failed TPMS sensor, register all tire-pressure sensor IDs with the scan tool, perform system initialization, clear DTC C2126, and verify all tire pressures display correctly.

CUSTOMER CONCERN After front-end collision repairs and replacement of the front bumper sensors, the parking-assist system stores DTCs C1AEC and C1AEE. CAUSE The replacement ultrasonic parking sensors had not completed detection-angle calibration and registration after the collision repair. CORRECTION Perform the ultrasonic sensor detection-angle procedures and intelligent-clearance sonar registration, clear DTCs C1AEC and C1AEE, and verify parking-assist operation.

CUSTOMER CONCERN The vehicle stalled while driving, required towing, and had a depleted high-voltage battery with DTCs P261A13, C1259, and C1A50. CAUSE The confirmed repair identified a failed 12-volt auxiliary battery as the cause of the stall and related hybrid-system faults. CORRECTION Remove and replace the failed 12-volt auxiliary battery, clear DTCs P261A13, C1259, and C1A50, and verify Ready mode, charging, and normal vehicle operation.
