If the initialization has not been completed successfully, Diagnostic Trouble Code (DTC) C2177/77 is set in the tire pressure 6. Confirm that initialization is complete by verifying that the correct tire pressure values are displayed on the intelligent tester. Tire Pressure Sensor Registration tire pressure monitor ECU prior to system initialization. See TIRE PRESSURE NOTE: When initializing the system, the present tire condition is stored as a standard. NOTE: Perform the tire pressure adjustment after the vehicle has sufficiently cooled NOTE: The initialization mode can be terminated by making a short circuit between NOTE: In winter, tire pressure may decrease due to low ambient temperatures NOTE: When a tire pressure sensor and/or tire pressure monitor ECU are replaced, the
