- Turn ignition switch to OFF position. Disconnect sun load sensor located on top center of dash top panel. Using scan tool, read SUN SENSOR voltage value. If reading is less than 0.2 volt, go to next step. If reading is greater than 0.2 volt, replace sun sensor. Perform VERIFICATION TEST .
- Disconnect Body Control Module BCM connectors C1 and C2. See Figure. Ensure connector terminals are making good contact. Repair connectors or terminals as necessary. Using a DVOM, measure resistance between ground and Dark Blue wire terminal of sun load sensor harness connector. If reading is 100 ohms or more, go to next step. If reading is less than 100 ohms, repair short to ground in sun load sensor signal circuit (Dark Blue wire). Perform VERIFICATION TEST .
- Using a DVOM, measure resistance between sun load sensor harness connector Dark Blue wire and Dark Blue/Gray wire terminals. If reading is less than 100 ohms, repair short between circuits. If reading is 100 ohms or more, replace BCM. See BODY CONTROL MODULES - CONCORDE, INTREPID, LHS & 300M article in ACCESSORIES & EQUIPMENT. Perform VERIFICATION TEST .
