Low Tire Pressure Indicator Inoperative; Repair Instructions - Suzuki XL7 2007 Service Manual

Low Tire Pressure Indicator Inoperative

Diagnostic Fault Information
Perform the "Diagnostic System Check - Tire Pressure
Monitoring" prior to using this diagnostic procedure.
Circuit/System Description
The remote control door lock receiver (RCDLR) sends a
serial data message to the instrument panel cluster
(IPC) requesting low tire pressure indicator illumination.

Replacement
Removal Procedure
1. Raise the vehicle on a suitable support. Refer to
"Lifting and Jacking the Vehicle: ".
2. Remove the tire/wheel assembly from the vehicle.
Refer to "Tire and Wheel Removal and Installation: ".
NOTE
Before the tire is removed from the wheel,
note the following items to avoid tire
pressure sensor damage upon tire
dismounting.
• Place the sensor's cap and valve on a dry
clean surface after removal. The cap is
aluminum and the valve is nickel plated to
prevent corrosion and are not to be
substituted with a cap or valve made of
any other material.
Circuit/System Testing
1. With the scan tool, select instrument panel special
functions Lamp Test. Command the instrument panel
lamps ON. Verify low tire pressure indicator lamp
turns ON.
➢ If the lamp does not turn ON, replace the IPC.
2. Using the tire pressure monitor (TPM) special tool to
observe the tire pressure of the suspected faulty
sensor. Check air pressure with a known accurate
hand held tire pressure gage. Compare the psi
reading to the display on the TPM special tool. Verify
pressure readings from special tool do not differ 2 psi
or more than actual tire pressure.
➢ If the difference is 2 psi more, replace the suspect
tire pressure sensor.
3. With the scan tool, observe tire pressures in the
scan tool data display. Verify pressure readings from
special tool do not differ 2 psi or more than scan tool
data display.
➢ If the difference is 2 psi more, replace the RCDLR.
