CUSTOMER CONCERN A 12-volt battery warning appears, the vehicle will not drive, and DTC P300000 is stored for hybrid battery discharge control. CAUSE The confirmed repair identified a failed 12-volt auxiliary battery. CORRECTION Remove and replace the failed 12-volt auxiliary battery, clear DTC P300000, and verify the vehicle enters Ready mode and drives normally.

CUSTOMER CONCERN Several instrument-panel fuse circuits have no voltage after an ignition-interlock installation. CAUSE The 50-amp J/B-B fuse in the engine-compartment fuse box was blown, removing power from multiple dash fuse circuits. CORRECTION Remove and replace the blown 50-amp J/B-B fuse and verify battery voltage is restored at the affected instrument-panel fuses.

CUSTOMER CONCERN After collision repairs, the parking-assist system stores DTCs C1AED and C1AF8 for rear sensor communication faults. CAUSE The rear intelligent-clearance sonar sensors had not been correctly aimed and registered after the collision repair. CORRECTION Perform the rear ultrasonic-sensor detection-angle procedures and intelligent-clearance sonar registration, clear DTCs C1AED and C1AF8, and verify parking-assist operation.
