Tire Pressure Monitoring System

Notes:
^ All the possible errors which can be detected and printed-out on the VAG1551 are listed below by their 5-digit malfunction code.
^ The malfunction code appears only on the printout.
^ Before replacing components indicated as malfunctioning, firstly check the leads and connectors for these components and the connections to Ground (GND), using the circuit diagram.
^ After completion of repair and function checking of the system, the DTC memory must always be checked again and cleared using scan tool VAG1551.
^ All static and sporadic malfunctions are stored in the DTC memory. A malfunction is classified as static if it occurs for not less than 2 seconds. If the malfunction is then no longer present, it is stored as a "sporadic" malfunction. "ISP" appears on the display
^ All malfunctions present are set to "sporadic" when the ignition is switched on and only stored as "static malfunctions" if they are still present after the check.
^ A sporadic malfunction is erased if it no longer occurs after 50 driving cycles (ignition on for not less than 5 minutes, speed > 30 km/h).
