Diagnostic Information - Non-DTC Based

No Response from Tire Pressure Monitoring Module






For a complete wiring diagram, refer to.






Test Step 1 - TEST FOR INTERMITTENT CONDITION

• Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

• Turn the ignition on.

• Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

• With the scan tool, read the module status.

• Check the TIPM for any active CAN hardware DTCs, perform DTC before proceeding.

Does the scan tool indicate that the module is active on the bus?

Yes

• 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.

No

• Go to Test Step 2

Test Step 2 - CHECK THE (A27) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT







• Turn the ignition off.

• Disconnect the Tire Pressure Module harness connector.

• Using a 12-volt test light connected to ground, check the (A27) Fused B(+) circuit.

Does the test light illuminate brightly?

Yes

• Go to Test Step 3

No

• Repair the open or short in the (A27) Fused B(+) circuit.

• Perform the Tire Pressure Monitor Verification Test. Refer to => [ Tire Pressure Monitor Verification Test ] Tire Pressure Monitor Verification Test.

Test Step 3 - CHECK THE (Z908) GROUND CIRCUIT FOR AN OPEN







• Using a 12-volt test light connected to 12-volts, check the (Z908) Ground circuit.

Does the test light illuminate brightly?

Yes

• Go to Test Step 4

No

• Repair the open in the (Z908) Ground circuit.

• Perform the Tire Pressure Monitor Verification Test. Refer to => [ Tire Pressure Monitor Verification Test ] Tire Pressure Monitor Verification Test.

Test Step 4 - CHECK THE (D52) CAN C BUS (+) CIRCUIT FOR AN OPEN







• Disconnect the TIPM C7 harness connector.

• 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 Test Step 5

No

• Repair the open in the (D52) CAN C Bus (+) circuit.

• Perform the Tire Pressure Monitor Verification Test. Refer to => [ Tire Pressure Monitor Verification Test ] Tire Pressure Monitor Verification Test.

Test Step 5 - CHECK THE (D51) CAN C BUS (-) CIRCUIT FOR AN OPEN







• 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 in accordance with the Service Information.

• Perform the Tire Pressure Monitor Verification Test. Refer to => [ Tire Pressure Monitor Verification Test ] Tire Pressure Monitor Verification Test.

No

• Repair the open in the (D51) CAN C Bus (-) circuit.

• Perform the Tire Pressure Monitor Verification Test. Refer to => [ Tire Pressure Monitor Verification Test ] Tire Pressure Monitor Verification Test.
