Diagnostic Test

DTC STATUS IS ACTIVE
NOTE: If the incorrect Placard Values were programmed into the WIN, a DTC could be set. Before continuing with any TPM diagnostic test, using the scan tool, check that the correct Placard Values have been programmed in to the module.
1. Ignition on, engine not running.
2. With the scan tool, record and erase read DTCs in the Wireless Ignition Node (WIN).
3. Test drive the vehicle for a minimum of 10 minutes with vehicle speed greater than 24 km/h (15 mph).
4. With the scan tool, read DTCs in the Wireless Ignition Node (WIN).
  Is the DTC status Active at this time?
  
  Yes
  - Go to step 2
  No
  - Go to step 8

1. Turn the ignition off.
2. Disconnect the Right Front TPM Transponder harness connector.
3. Disconnect the WIN harness connector.
4. Ignition on, engine not running.
5. Using a 12-volt test light connect to ground, check the (F924) Fused Ignition Switch Output (Run) circuit.
  NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go to step 3
  No
  - Repair the (F924) Fused Ignition Switch Output (Run) circuit for an open circuit or high resistance.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
(Z924) GROUND CIRCUIT(S) OPEN OR HIGH RESISTANCE

1. Turn the ignition off.
2. Using a 12-volt test light connect to 12 volts, check each of the (Z924) Ground circuit(s).
  NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
  
  Is the test light illuminated and bright?
  
  Yes
  - Go to step 4
  No
  - Repair the (Z924) Ground circuit(s) for an open circuit or high resistance.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .

1. Turn the ignition off.
2. Disconnect the remaining two TPM Transponder harness connectors.
3. Ignition on, engine not running.
4. 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.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
  No
  - Go to step 5
(D508) COM-LIN TIRE PRESSURE MONITOR LAN CIRCUIT SHORTED TO GROUND

1. Turn the ignition off.
2. Measure the resistance between ground and the (D508) COM-LIN Tire Pressure Monitor LAN circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (D508) COM-LIN Tire Pressure Monitor LAN circuit for a short to ground.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
  No
  - Go to step 6
(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 WIN harness connector.
2. Using a 12-volt test light connected to battery voltage, check the (D508) COM-LIN Tire Pressure Monitor LAN circuit in the Right Front TPM Transponder 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 bright?
  
  Yes
  - Go to step 7
  No
  - Repair the (D508) COM-LIN Tire Pressure Monitor LAN circuit for an open circuit or high resistance.
  - Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
RIGHT FRONT TIRE PRESSURE MONITORING (TPM) TRANSPONDER
1. Turn the ignition off.
2. Replace the Right Front TPM Transponder in accordance with the Service Information.
  Perform the TPM VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
3. With the scan tool, erase DTCs.
4. Test drive the vehicle for a minimum of 10 minutes with vehicle speed greater than 24 km/h (15 mph)
5. With the scan tool, read DTCs in the Wireless Ignition Node (WIN).
  Does the DTC reset or is the status Active for this DTC?
  
  Yes
  - Replace the Wireless Ignition Node (WIN) in accordance with the Service Information.
  - Perform the WIN VERIFICATION TEST. See DTC-Based Diagnostics/NODE, Wireless Ignition (WIN) - Standard Procedure .
  No
