3. (D506) LIN BUS CIRCUIT OPEN BETWEEN THE CLUSTER AND LEFT MULTIFUNCTION SWITCH Turn the ignition off. Disconnect the Cluster C2 harness connector. Measure the resistance of the (D506) LIN BUS circuit. Is the resistance below 5.0 Ohms? Yes Replace the Cluster in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure»(ref-350093-S36937059432009121400000) . No Repair the open in the (D506) LIN BUS circuit. Perform the BODY VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure»(ref-350093-S36937059432009121400000) .
4. (F943) FUSED RUN/START RELAY OUTPUT CIRCUIT OPEN Measure the voltage of the (F943) Fused RUN/START Relay Output circuit at the Left Multifunction Switch harness connector. Is the voltage above 10.0 volts? Yes Go to step 5 No Repair the open in the (F943) Fused RUN/START Relay Output. Perform the BODY VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure»(ref-350093-S36937059432009121400000) .
5. (Z910) GROUND CIRCUIT OPEN Turn the ignition off. Measure the resistance between ground and the (Z910) Ground circuit at the Left Multifunction Switch harness connector. Is the resistance below 5.0 Ohms? Yes Replace the Left Multifunction Switch in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure»(ref-350093-S36937059432009121400000) . No Repair the open in the (Z910) ground circuit. Perform the BODY VERIFICATION TEST. Refer to «DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure»(ref-350093-S36937059432009121400000) .
