SUBJECT VEHICLES: Acura models covered and model year(s): ILX 2016, MDX 2007-16, RDX 2007-16, RLX 2014-16, TL 2009-14, TLX 2015-16, TSX 2009-14, ZDX 2010-13.


SPECIAL TOOLS NEEDED? The Honda Diagnostic System (HDS) or an OBD-II compatible scan tool.

With the Acura models listed, whenever the engine is running, the tire pressure monitoring system (TPMS) control unit continuously monitors all four tires and the system.

The system has seven indicators: four tire indicators, a low pressure indicator, a message indicator and a TPMS indicator. If the TPMS control unit detects pressure below the lower limit, it alerts the driver by turning on the low pressure indicator, turning on the appropriate tire(s) indicator on the multi-information display as well as the message indicator, and setting a diagnostic trouble code (DTC) in the control unit.

When the tire pressure is increased to normal the control unit will turn off the indicators and store the DTC(s). When two or more tire pressures are low, the low pressure indicator comes on about five seconds before the appropriate tire indicator. Once low pressure is detected, the system scans all four pressure sensors to ensure that it turns on the correct tire indicator. If a problem is detected in the system, the TPMS indicator will come on. If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on.

When the system detects a problem, the TPMS control unit sets a code, but shifts to fail-safe mode, and does not alert the driver to low tire pressures. If the TPMS control unit loses power or fails, the TPMS indicator will come on, but no DTC will be set.
