C151D
C151D-TIRE PRESSURE SENSOR LOCATION UNDERETEMINED
Theory of Operation
The vehicle sensor locate process occurs after the vehicle sits at zero speed for more than 20 minutes. The Tire Pressure Monitoring (TPM) System will determine the Tire Pressure Monitoring (TPM) Sensor positions while driving at speeds above 15 mph (24 Km/h). This process can take up to 20 minutes to determine TPM Sensor positions.
- When Monitored:
During vehicle sensor locate process.
- Set Condition:
Must fail vehicle sensor locate process three times in a row.

Yes
- Go To 5
No
- Repair the Fused Ignition Switch Output (Run) circuit for an open circuit or high resistance.
- Perform TPM VERIFICATION TEST Tire Pressure Monitor (TPM) Verification Test.
5. GROUND CIRCUIT(S) OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Using a 12-volt test light connect to battery voltage, probe each of the Ground circuit(s).
NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
Does the test light illuminate brightly?
Yes
- Go To 6
No
- Repair the Ground circuit(s) for an open circuit or high resistance.
- Perform TPM VERIFICATION TEST Tire Pressure Monitor (TPM) Verification Test.
6. (D508) COM - LIN TIRE PRESSURE MONITOR LAN CIRCUIT SHORT TO VOLTAGE
1. Ignition on, engine not running.
2. Measure the voltage of the (D508) Com-Lin Tire Pressure Monitor Lan circuit.
Is there any voltage present?
Yes
- Repair the (D508) COM - LIN Tire Pressure Monitor LAN circuit for a short to voltage.
No
- Go To 7
- Perform TPM VERIFICATION TEST Tire Pressure Monitor (TPM) Verification Test.
7. (D508) COM - LIN TIRE PRESSURE MONITOR LAN CIRCUIT SHORT TO GROUND
1. Turn the ignition off.

Yes
- Repair the (D508) COM - LIN Tire Pressure Monitor LAN circuit for a short to ground.
- Perform TPM VERIFICATION TEST Tire Pressure Monitor (TPM) Verification Test.
No
- Go To 8
8. (D508) COM - LIN TIRE PRESSURE MONITOR LAN CIRCUIT OPEN OR HIGH RESISTANCE
1. Use a jumper wire with one end connected to ground and the other to the (D508) COM - LIN Tire Pressure Monitor LAN circuit in the Front Left Tire Pressure Transponder harness connector.
2. Using a 12-Volt test light connected to battery voltage, probe the (D508) COM - LIN Tire Pressure Monitor LAN circuit in the TPM harness connector.
NOTE: The test light should be illuminated and bright. Compared the brightness to that of a direct connection to the battery.
Does the test light illuminate brightly?
Yes
- Go To 9
No
- Repair the (D508) COM - LIN Tire Pressure Monitor LAN circuit for an open circuit or high resistance.
- Perform TPM VERIFICATION TEST Tire Pressure Monitor (TPM) Verification Test
9. POWER AND GROUND CIRCUIT OPEN
