LOW LINE:
Wheel sensor to ECU communication takes place every 3 minutes, 20 seconds for TRW systems
and every 3 minutes for Lear systems unless rapid tire deflation is occuring. Be sure to wait this
amount of time for the values to populate on the Current Data Screen.
ROAD TEST:
To verify your repair drive the vehicle at or above 20 MPH for 20 minutes, if speed goes below 20
MPH during Auto-Learn (TRW only), the process is halted until speed is above threshold again.
Auto-Learn (TRW only), is not recommended, use exciter tool each time to program the sensor ID's
into the receiver module.
TPMS Drive Cycle
The warning light shown above = indicates Low tire pressure problem, use exciter tool and match
tire pressure on-screen value against your tire pressure gauge reading. The tire pressures should
be set COLD.
Inaccurate tire gauges should be replaced immediately to prevent comebacks.
