Circuit/System Testing

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inflate tires to the proper pressure. Refer to VEHICLE CERTIFICATION, TIRE PLACARD, ANTI-THEFT, AND SERVICE PARTS ID LABEL .
  2. Using the tire pressure monitor (TPM) special tool, activate each tire pressure sensor and record each sensors tire pressure reading in psi. Check tire pressures with a known accurate hand held tire pressure gauge. Verify pressure readings from special tool do not differ 4 psi or more lower than actual tire pressure.
    • If 4 psi or more lower than actual tire pressure, replace the suspect tire pressure sensor.
  3. With the scan tool, select instrument panel special functions Lamp Test. Command the instrument panel warning lamps OFF. Verify low tire pressure indicator lamp turns OFF.
    • If the lamp does not turn OFF, replace the IPC.
  4. Enable the TPM learn mode. Use the TPM special tool in simulate mode to learn 4 simulated sensor transmissions into the RCDLR. Observe tire pressures in the scan tool data display. Verify simulated tire pressures do not differ more than +/- 4 psi of the scan tool reading.
    • If the tire pressures differ more than +/- 4 psi, replace the RCDLR.
