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

Test E1:

Test E1-E2:

Normal Operation
The tire pressure monitoring system module communicates with the diagnostic tool through the SCP communications network circuits 914 (TN/OG) and 915 (PK/LB). 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 914 (TN/OG) and 915 (PK/LB) 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 circuit 914 (TN/OG) or 915 (PK/LB), damage to the DLC C251, damage to the tire pressure monitoring system module C3183, or a problem in the in-line connector.

Possible Causes
- SCP circuit 914 (TN/OG) or 915 (PK/LB) shorted to ground or open
- DLC C251
- tire pressure monitoring system module
- tire pressure monitoring system module C3183
