No Response From TPM (Tire Pressure Monitor Module)

NO RESPONSE FROM TPM (TIRE PRESSURE MONITORING) MODULE












1. TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.

NOTE: Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 Volts.

2. Using 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 diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

2. (A27) FUSED B(+) CIRCUIT OPEN OR SHORTED




1. Turn the ignition off.
2. Disconnect the Tire Pressure Module harness connector.
3. Using a 12-volt test light connected to ground, check the (A27) Fused B(+) circuit.

Does the test light illuminate brightly?

Yes

- Go To 3

No

- Repair the open or short in the (A27) Fused B(+) circuit.
- Perform the TPM VERIFICATION TEST. TPM Verification Test.

3. (Z906) GROUND CIRCUIT OPEN




1. Using a 12-volt test light connected to 12-volts, check the (Z906) Ground circuit.

Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the open in the (Z906) Ground circuit.
- Perform the TPM VERIFICATION TEST. TPM Verification Test.

4. (D52) CAN C BUS (+) CIRCUIT OPEN




1. Disconnect the TIPM C7 harness connector.
2. Measure the resistance of the (D52) CAN C Bus (+) circuit between the TIPM C7 harness connector and the Tire Pressure Module harness connector.

Is resistance below 5.0 Ohms?

Yes

- Go To 5

No

- Repair the open in the (D52) CAN C Bus (+) circuit.
- Perform the TPM VERIFICATION TEST. TPM Verification Test.

5. (D51) CAN C BUS (-) CIRCUIT OPEN




1. Measure the resistance of the (D51) CAN C Bus (-) circuit between the TIPM C7 harness connector and the Tire Pressure Module harness connector.

Is resistance below 5.0 Ohms?

Yes

- Replace the TPM module.
- Perform the TPM VERIFICATION TEST. TPM Verification Test.

No

- Repair the open in the (D51) CAN C Bus (-) circuit.
- Perform the TPM VERIFICATION TEST. TPM Verification Test.
