PINPOINT TEST D: THE TIRE PRESSURE MONITORING SYSTEM MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

Test D1-D3:

Normal Operation
The tire pressure monitoring system module communicates with the diagnostic tool through the controller area network (CAN) circuits 3125 (RD/YE) and 3126 (TN/YE). If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost, communications can continue. Check circuits 3125 (RD/YE) and 3126 (TN/YE) between the tire pressure monitoring system module C3183 and the data link connector (DLC) C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in the CAN circuits, damage to the DLC C251, damage to the tire pressure monitoring system module C3183, or a problem in the in-line connectors.

Possible Causes
- circuit 3125 (RD/YE) and 3126 (TN/YE) shorted to ground or open
- DLC C251
- tire pressure monitoring system module
- tire pressure monitoring system module C3183
