*NO RESPONSE FROM TPM (TIRE PRESSURE MONITOR MODULE)





For a complete wiring diagram Consult Diagrams/Electrical.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.

NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

With the scan tool, select ECU view.

NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.

Does the scan tool display a red X next to the module?

Yes

- Go To 2

No

- The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.

2. GROUND CIRCUIT OPEN




Turn the ignition off.
Disconnect the Tire Pressure Monitor Module harness connector.
Using a 12-volt test light connected to 12-volts, check the ground circuit.
Does the test light illuminate brightly?

Yes

- Go To 3

No

- Repair the ground circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1.Verification Tests.

3. FUSED B(+) CIRCUIT OPEN OR SHORTED




Using a 12-volt test light connected to ground, check the Fused B(+) circuit.
Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the Fused B(+) circuit for an open or short.
- Perform the BODY VERIFICATION TEST - VER 1.Verification Tests.

4. CAN B BUS CIRCUITS OPEN




NOTE: One open circuit will not cause this condition.

Turn the ignition on.
Measure the voltage between the CAN B Bus (-) circuit and ground.
Measure the voltage between the CAN B Bus (+) circuit and ground.
Is there any voltage present on either circuit?

Yes

- Replace the Tire Pressure Monitor Module.
- Perform the BODY VERIFICATION TEST - VER 1.Verification Tests.

No

- Inspect the connector for damage. Repair the CAN B Bus circuits for an open.
- Perform the BODY VERIFICATION TEST - VER 1.Verification Tests.
