Allocation of wheel electronics units using > 9900 - PIWIS Tester 3 : >>Tyre Pressure Monitoring (TPM) system<<>>Maintenance/repairs<<>>Teach wheel IDs<<>>Teach wheel IDs while vehicle is stationary<<>>Wheel IDs unknown<<.
Always observe the following procedure (instructions on the System Tester always take precedence!):
- Allow an idle time of at least 5 minutes before teaching the wheel IDs (wheel electronics units are then in Sleep mode).
- As per instructions on the System Tester, pressure (at least 0.2 bar and approx. 5 seconds) at the wheels must be reduced.
- The wheel electronics registers the pressure difference (after 2 minutes at the latest) and switches to Burst mode.
- The control unit receives the telegrams from the activated wheel electronics unit and writes its wheel ID to the specified position.
