WT-40 < COMPONENT DIAGNOSIS > TIRE PRESSURE RECEIVER TIRE PRESSURE RECEIVER Description INFOID:0000000000957904 The tire pressure receiver receives the air pressure signal transmitted by the transmitter in each wheel. Diagnosis Procedure INFOID:0000000000957905 1. CHECK TIRE PRESSURE RECEIVER 1. Turn ignition OFF. 2. Check tire pressure receiver connector M101 terminal 2 and ground signal with oscilloscope. Is the reference signal inputted? YES >> INSPECTION END NO >> GO TO 2. 2. CHECK TIRE PRESSURE RECEIVER INPUT VOLTAGE 1. Disconnect tire pressure receiver connector. 2. Check voltage between tire pressure receiver connector M101 terminal 4 and ground. Is the reference voltage inputted? YES >> GO TO 3. NO >> Check BCM harness and connector. 3. CHECK TIRE PRESSURE RECEIVER GROUND CIRCUIT 1. Disconnect BCM harness connector and tire pressure receiver connector. 2. Check continuity between BCM harness connector M123 terminal 137 and tire pressure receiver connec- Also check harness for short to ground. Is the inspection result normal?
