C0775 2017 GMC Sierra Code - Tire Pressure Monitoring System Sensors Malfunction
Quick Answer
If the Body Control Module (BCM) has been reprogrammed or replaced and the tire pressure sensor learn procedure has not been performed, the tire pressure monitor system indicator icon on the instrument cluster will flash for 1 min and then remain illuminated after the power switch is cycled ON and the instrument cluster bulb check is complete. Common causes include Relearn Low Tire Pressure System Sensors. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about C0775 2017 GMC Sierra Code
1. What does OBDII code C0775 mean on a 2017 GMC Sierra?
Code C0775 indicates a malfunction in the Tire Pressure Monitoring System (TPMS), specifically related to one or more TPMS sensors.
2. What are the common symptoms of code C0775 on a 2017 GMC Sierra?
Symptoms may include an illuminated TPMS warning light, inaccurate tire pressure readings, or no pressure readings displayed on the dashboard.
3. What causes code C0775 on a 2017 GMC Sierra?
Causes can include a faulty or dead TPMS sensor, interference with the sensor's signal, damaged wiring, or an issue with the TPMS module.
4. Can low tire pressure trigger code C0775 on a GMC Sierra?
No, low tire pressure itself does not trigger this code. However, a malfunctioning TPMS sensor may prevent accurate tire pressure monitoring.
5. How do you diagnose code C0775 on a 2017 GMC Sierra?
Diagnosis involves scanning the vehicle with an OBDII scanner, checking the TPMS sensor battery life, inspecting for physical damage, and testing signal communication.
6. How much does it cost to fix code C0775 on a 2017 GMC Sierra?
The cost depends on the issue, but replacing a single TPMS sensor typically ranges from $50 to $150, including parts and labor.
7. Can I drive with code C0775 on my 2017 GMC Sierra?
Yes, but it is not recommended as the TPMS system may not alert you to low tire pressure, increasing the risk of tire damage or unsafe driving conditions.
8. How do you reset the TPMS after fixing code C0775 on a GMC Sierra?
After repairs, use a TPMS reset tool or follow the vehicle’s relearn procedure, which typically involves setting the correct tire pressures and cycling the ignition.
9. Can a dead TPMS sensor battery cause code C0775 on a GMC Sierra?
Yes, a dead TPMS sensor battery is a common cause of this code, as it prevents the sensor from transmitting data.
10. Do I need to replace all TPMS sensors if one fails on a 2017 GMC Sierra?
Not necessarily. You can replace only the faulty sensor, but if all sensors are the same age, others may fail soon due to similar wear.
