Affected Vehicles
Condition
^ Message "TPMS Tire pressure! System malfunction" appears in instrument cluster display.
^ DTC 03543 (low availability) stored in ABS/ESP address word 03 (J104).
Technical Background
A software concern causes the low availability counter to reach the threshold for DTC 03543 too quickly. Integrated in TPMS (Tire Pressure
Monitoring System) control is a counter that tracks system unavailability (low availability) due to certain driving conditions such as extremely rough
roads. A software concern causes the counted value to be overstated with each ignition OFF cycle.
If a vehicle is driven primarily for short trips at low speeds, and is used infrequently on the highway, the counter may reach the threshold for DTC
03543 because of frequent cycling of the ignition.
Production Solution
Optimized software from production month November 2010.
