Diagnosis And Testing - Tire Pressure Monitoring: Notes

When diagnosing a tire pressure issue, first check the Tire Pressure Monitoring (TPM) indicator lamp in the instrument cluster during ignition key ON. From the OFF position, turn the key to ON and check the TPM indicator lamp to observe one of the following:

• If after 10 seconds the indicator lamp is illuminating continuously (not flashing), proceed to LOW PRESSURE  .
• If after 10 seconds the indicator lamp flashes on/off for 75 seconds, then remains on solid, there is a system fault detected. Proceed to SYSTEM FAULT  .
