P0A80: dust buildup in battery cooling passages (US 2013–2014 Camry HV case)

Symptoms

• The engine MIL comes on and P0A80 is stored; this entry covers only the blockage conditions described in the bulletin. ^[1]

Diagnostic trouble codes

• P0A80 (generic): Replace Hybrid Battery Pack (the manufacturer's DTC title quoted in the bulletin); the actual repair still depends on the inspection branch. ^[1]

Possible causes

• The fault in this bulletin is caused by dust and debris blocking the high-voltage battery fan or internal air duct filter. ^[1]

Checks

• A qualified technician checks the fan or internal filter using the VIN-based inspection branch; if the specified blockage is not found, this bulletin does not apply. Proceed with diagnosis using the full repair manual. ^[1]

What to do

• When the conditions are met, service the fan/filter and replace the battery assembly according to the bulletin; this must not be simplified to dust cleaning alone. Follow the model-specific repair manual for high-voltage removal and installation, then clear the codes and road-test. ^[1]
