Code Tech Notes
Some aftermarket wheel valve stem holes are located further from the wheel rim than the original equipment wheels. When using the tire pressure monitor special tool to activate a sensor, ensure the tool is placed along the tire sidewall and no further than 15 cm (6 in) from the sensor and the antenna is aiming upward.
Occasionally sensors can become mislocated due to previous tire rotations where the sensor learn procedure was not performed. Always learn the sensors to ensure the DTC set is for that actual physical corner of the vehicle.
A sensor with low battery condition will set a sensor DTC but will not illuminate the low tire pressure indicator or display a message on the driver information center if equipped. The sensor battery condition can be verified in the scan tool BCM data list. If a sensor's low battery condition is indicated on the scan tool, the sensor will need to be replaced.
