C1245 SATURN Description
The Tire Pressure Monitor (TPM) system uses the Electronic Brake Control Module (EBCM) and ABS wheel speed sensor inputs to monitor tire pressure. EBCM contains software to calculate relative tire pressure differences. EBCM monitors ABS wheel speed sensor inputs, which will all be same as learned calibration if tire pressures stay same. If pressure increases or decreases in one tire, tire circumference and radius will change and cause that wheel speed sensor input to change. EBCM recognizes this change in wheel speed as a tire pressure condition. TPM system is disabled when DTC is set.
