  1. CHECK FOR AN ACTIVE DTC NOTE: 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. Turn the ignition on. With the scan tool, read DTCs. Does the scan tool display this DTC as active? Yes Go To 2 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.
  2. (D506) LIN BUS CIRCUIT OPEN Turn the ignition off. Disconnect the Left Multifunction Switch C1 harness connector. Turn the ignition on. Measure the voltage of the (D506) LIN BUS circuit. Is the voltage above 5.0 volts? Yes Go To 3 No Repair the open in the (D506) LIN BUS circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612758-S33453045902014043000000) .
  3. (F202) IGNITION SWITCH OUTPUT (RUN/START) CIRCUIT OPEN Measure the voltage of the (F202) Ignition Switch Output (RUN/START) circuit. Is the voltage above 10.0 volts? Yes Go To 4 No Repair the open in the (F202) Ignition Switch Output (RUN/START) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612758-S33453045902014043000000) .
  4. (A411) FUSED B(+) (I.O.D.) CIRCUIT OPEN Measure the voltage of the (A411) Fused B(+) (I.O.D.) circuit. Is the voltage above 10.0 volts? Yes Go To 5 No Repair the open in the (A411) Fused B(+) (I.O.D.) circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612758-S33453045902014043000000) .
  5. (Z903) GROUND CIRCUIT OPEN Measure the resistance between ground and the (Z903) Ground circuit. Is the resistance below 10K Ohms? Yes Replace the Left Multifunction Switch in accordance with the Service Information. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612758-S33453045902014043000000) . No Repair the open in the (Z903) Ground circuit. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(ref-612758-S33453045902014043000000) .
