DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
TPMS Reminder Reset - Procedure 03
When tire pressure is low, the "Low Tire" Pressure Indicator Lamp signal circuit will be pulsed to ground by the TPM module for two seconds on and then two seconds off, over and over. The BCM will then illuminate the "Low Tire" Pressure Indicator Lamp at the same rate and sound the audible chime as one single long tone.
When tire pressure is critical, the low tire pressure warning lamp signal circuit will be pulsed to ground by the low tire pressure warning module for one second on and then one second off, over and over. The BCM will then illuminate the "Low Tire" Pressure Indicator Lamp and sound the audible chime at the rate of one second on and one second off.
In either case, the TPM module will continue to pulse to ground the "Low Tire" Pressure Indicator Lamp signal circuit until the sensor/transmitter(s) transmits a pressure above the calibrated thresholds (and car is then driven above 20 mph (32 km/h)) or the ignition is turned off. If the conditions has not been corrected when the ignition is turned off, the indicator lamp will remain off when the ignition is turned on again until the vehicle reaches a speed of approximately 20 mph (32 km/h).
