The Cluster does not receive information from the Right Steering Wheel Switch. Possible Causes (D5) LIN BUS CIRCUIT OPEN (A99) FUSED B(+) CIRCUIT OPEN (Z9) GROUND CIRCUIT OPEN STEERING WHEEL SWITCH. CHECK FOR AN ACTIE DTC NOTE:. Turn the ignition on. Before proceeding with this diagnostic procedure, verify the Left and Right Multifunction Switch and Clockspring harness connectors are properly seated and verify proper pin terminal tension. A loose connection at any of these connectors may cause this DTC to set.. With the scan tool, read DTCs. Does the scan tool display this DTC as active? Yes Go To No Test complete, the condition or conditions that originally set this DTC are 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.. CHECK THE OLTAGE OF (D5) LIN BUS CIRCUIT AT THE STEERING WHEEL SWITCH. Turn the ignition off.. Disconnect the Right Steering Wheel Switch harness connector.. Turn the ignition on. 4. Measure the voltage of the (D5) LIN Bus circuit at the Right Steering Wheel Switch harness connector. Is the voltage above 5. volts? Yes Go To 5 No Go To 5449

Measure the resistance of the (D5) LIN Bus circuit between the Right Steering Wheel Switch and Clockspring C8 harness connectors. Is the resistance below 5. Ohms? Yes Go To 4 C8 No Repair the open in the (D5) LIN Bus circuit. (Refer to 8 - DTC-Based Diagnostics/ 54459 4. CHECK THE OLTAGE OF (D5) LIN BUS CIRCUIT AT THE. Disconnect the Clockspring C harness connector.. Turn the ignition on.. Measure the voltage of the (D5) LIN Bus circuit at the Clockspring C harness connector. Is the voltage above 5. volts? Yes Replace the Clockspring in accordance with the Service Information. (Refer to 8 - DTC-Based Diagnostics/ No Repair the open in the (D5) LIN Bus circuit. (Refer to 8 - DTC-Based Diagnostics/ C 5447
5. CHECK THE OLTAGE OF (A99) FUSED B(+) CIRCUIT AT THE STEERING WHEEL SWITCH. Measure the voltage of the (A99) Fused B(+) circuit at the Right Steering Wheel Switch harness connector. Is the voltage above. volts? Yes Go To 8 No Go To 544. (A99) FUSED B(+) CIRCUIT OPEN BETWEEN THE STEERING WHEEL SWITCH AND. Turn the ignition off.. Disconnect the Clockspring C8 harness connector.. Measure the resistance of the (A99) Fused B(+) circuit between the Right Steering Wheel Switch and Clockspring C8 harness connectors. Is the resistance below 5. Ohms? Yes Go To 7 No Repair the open in the (A99) Fused B(+) circuit. C8 (Refer to 8 - DTC-Based Diagnostics/ 5448 4
7. (A99) FUSED B(+) CIRCUIT OPEN BETWEEN THE AND TOTALLY INTEGRATED POWER MODULE. Turn the ignition off.. Disconnect the Clockspring C harness connector.. Turn the ignition on. 4. Measure the voltage of the (A99) Fused B(+) circuit at the Clockspring C harness connectors. Is the voltage above. volts? Yes Replace the Clockspring in accordance with the Service Information. (Refer to 8 - DTC-Based Diagnostics/ No Repair the open in the (A99) Fused B(+) circuit. (Refer to 8 - DTC-Based Diagnostics/ C 544 8. CHECK THE (Z9) GROUND CIRCUIT AT THE STEERING WHEEL SWITCH. Turn the ignition off.. Measure the resistance between ground and the (Z9) Ground circuit at the Right Steering Wheel Switch harness connector. Is the resistance below 5. Ohms? Yes Replace the Right Steering Wheel Switch in accordance with the Service Information. 8 (Refer to 8 - DTC-Based Diagnostics/ No Go To 9 5448 5
9. (Z9) GROUND CIRCUIT OPEN BETWEEN THE STEERING WHEEL SWITCH AND. Disconnect the Clockspring C8 harness connector.. Measure the resistance of the (Z9) Ground circuit between the Right Steering Wheel Switch and Clockspring C8 harness connectors. Is the resistance below 5. Ohms? Yes Go To C8 No Repair the open in the (Z9) Ground circuit. (Refer to 8 - DTC-Based Diagnostics/ 8 54494. (Z9) GROUND CIRCUIT OPEN BETWEEN THE AND GROUND. Disconnect the Clockspring C harness connector.. Measure the resistance between ground and the (Z9) Ground circuit at the Clockspring C harness connector. Is the resistance below 5. Ohms? Yes Replace the Clockspring in accordance with the Service Information. (Refer to 8 - DTC-Based Diagnostics/ No Repair the open in the (Z9) Ground circuit. (Refer to 8 - DTC-Based Diagnostics/ C 5447
