Signal Tech II Updates
If service is required on a vehicle's Tire Pressure Monitor System (TPMS), remote keyless entry, or Intelligent Key, the Signal Tech II (special tool J-50190) can be used for diagnostics.
Signal Tech II will quickly:
- Activate and display TPMS Sensor IDs
- Display tire pressure reported by the TPMS sensor
- Read TPMS DTCs and register TPMS IDs
- Store and print reports for warrantable repairs
- Check Intelligent Key relative signal strength
- Test remote keyless entry, and Remote Start (RES), relative signal strength
- Confirm vehicle Intelligent Key antenna relative signal strength output
- Displays OBD-II Engine codes
Check for Signal Tech II software updates
It is important to perform software updates when new models aren't listed on the STII menu, for the Signal Tech II tool to receive required data for new vehicles. Updating will provide your Signal Tech II with the Select Model listing by adding new models, as well as the model year updates to the list. This will help to ensure that you'll have the correct diagnostics.
Note: Failure to update Signal Tech II may lead to misdiagnosis of certain models.
