Step	Action	Yes	No
Schematic Reference: Headlights/Daytime Running Lights (DRL) Schematics Connector End View Reference: Lighting Systems Connector End Views or Data Communication Connector End Views DEFINITION: This table is for export vehicles that utilize the low beam headlamps and park lamps as daytime running lamps (DRL).
1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Turn ON the ignition, with the engine OFF. Press and hold the brake pedal. Move the gear selector out of the PARK position on vehicles with automatic transmissions or release the parking brake on vehicles with manual transmissions. Verify that the headlamp switch is in the OFF position. Expose the ambient light sensor to a bright light. Wait more than 3 seconds. Do the DRL headlamps operate properly?	Go to Testing for Intermittent Conditions and Poor Connections	Go to Step 3
3	With a scan tool, select the Daytime Running Lamp parameter from the Special Functions Output Controls data list. Command the Daytime Running Lamp output control ON and OFF. Do the DRL turn ON and OFF with each command?	Go to Step 5	Go to Step 4
4	Do the low beam headlamps function properly?	Go to Step 7	Go to Headlamps Inoperative - Low Beams (Standard or w/TR7-TT6) or Headlamps Inoperative - Low Beams (w/HID (TT6)) or Headlamps Inoperative - Low Beams (w/Leveling (TR7) and HID (TT6))
5	Is the vehicle equipped with a manual transmission?	Go to Step 6	Go to Step 12
6	With a scan tool, observe the Park Brake Switch parameter in the instrument panel cluster (IPC) Inputs data list. Does the scan tool display an OFF status?	Go to Step 12	Go to Diagnostic System Check - Vehicle
7	Turn OFF the ignition. Disconnect the DRL relay. Connect a test lamp between the DRL relay control side supply voltage circuit and a good ground. Turn ON the ignition, with the engine OFF. Does the test lamp illuminate?	Go to Step 8	Go to Step 15
8	Connect a test lamp between the DRL relay switch side supply voltage circuit and a good ground. Does the test lamp illuminate?	Go to Step 9	Go to Step 16
9	Connect a test lamp between the DRL relay control side supply voltage circuit and the DRL relay control circuit at the DRL relay connector. With a scan tool, command the Daytime Running Lamps ON and OFF. Does the test lamp turn ON and OFF with each command?	Go to Step 10	Go to Step 11
10	Turn OFF the ignition. Connect a 10-amp fused jumper between the DRL relay switch side supply voltage circuit and the DRL headlamp supply voltage circuit. Turn ON the ignition, with the engine OFF. Do the DRL headlamps illuminate?	Go to Step 13	Go to Step 17
11	Test the DRL relay control circuit for an open or a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 20	Go to Step 14
12	With a scan tool, observe the Photocell status in the climate control panel (CCP) Inputs data list. Does the scan tool display a Light status?	Go to Step 14	Go to Twilight Sentinel Inoperative
13	Inspect for poor connections at the DRL relay. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 20	Go to Step 18
14	Inspect for poor connections at the dash integration module (DIM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 20	Go to Step 19
15	Repair the open in the DRL relay control side supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 20	-
16	Repair the open in the DRL relay switch side supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 20	-
17	Repair the open in the DRL headlamp supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 20	-
18	Replace the DRL relay. Refer Relay Replacement (Attached to Wire Harness) or Relay Replacement (Within an Electrical Center) . Did you complete the replacement?	Go to Step 20	-
19	Replace the DIM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	Go to Step 20	-
20	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 2
