1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Place the headlamp switch in the PARK position. Do the park lamps illuminate?	Go to Testing for Intermittent Conditions and Poor Connections	Go to Step 3
3	Is only one lamp inoperative?	Go to Step 4	Go to Step 5
4	Disconnect the inoperative lamp. Probe the park lamp supply voltage circuit of the inoperative lamp with a test lamp that is connected to a good ground. Does the test lamp illuminate?	Go to Step 12	Go to Step 13
5	Are all of the park lamps inoperative?	Go to Step 6	Go to Step 7
6	Turn ON the ignition, with the engine OFF. With a scan tool, observe the Park Lamp Input parameter in the Lamp Status data list. Does the scan tool display the Park Lamp Input parameter as On?	Go to Step 14	Go to Step 10
7	Are the front park lamps inoperative?	Go to Step 8	Go to Step 9
8	Test for an open or high resistance in the park lamp supply voltage circuit between splice 216 and the front park lamps. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 18	Go to Step 15
9	Test for an open or high resistance in the park lamp supply voltage circuit between splice 216 and the rear park lamps. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 18	Go to Step 16
10	Test the park lamp supply voltage circuit for an open or high resistance between the headlamp switch and splice 216. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	Go to Step 18	Go to Step 11
11	Inspect for poor connections at the harness connector of the headlamp switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	Go to Step 18	Go to Step 17
12	Repair an open or high resistance in the ground circuit of the inoperative lamp. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 18	-
13	Repair an open, high resistance, or short to ground in the park lamp supply voltage circuit of the inoperative lamp. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 18	-
14	Repair an open or high resistance in the park lamp supply voltage circuit at splice 216. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 18	-
15	Repair an open or high resistance in the ground circuit of the front park lamps. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 18	-
16	Repair an open or high resistance in the ground circuit of the rear park lamps. Refer to Circuit Testing and Wiring Repairs . Did you complete the repair?	Go to Step 18	-
17	Replace the headlamp switch. Refer to Turn Signal Multifunction Switch Replacement . Did you complete the repair?	Go to Step 18	-
18	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 3
