10 | Test the turn/hazard module signal circuit for an open, short to ground or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 17 |
11 | Connect a test lamp between the turn/hazard module 2 supply voltage circuit of the turn/hazard flasher and a good ground. Does the test lamp illuminate? | Go to Step 17 | Go to Step 12 |
12 | Test the turn/hazard module 2 supply voltage circuit of the turn/hazard flasher for an open, short to ground or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 13 |
13 | Test the ignition 1 voltage circuit of the turn/hazard switch for an open, short to ground or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 19 |
14 | Test the appropriate turn signal circuit for a short to ground, open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 19 |
15 |
Does the test lamp illuminate with the turn signal? | Go to Step 18 | Go to Step 20 |
16 | Test the appropriate turn signal circuit for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 21 |
17 | Inspect for poor connections at the harness connector of the turn hazard flasher connector. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 22 |
18 | Inspect for poor connections at the harness connector of the instrument cluster connector. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 23 |
19 | Inspect for poor connections at the harness connector of the turn/hazard switch. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 25 | Go to Step 24 |
20 | Repair the high resistance or an open in the turn signal indicator lamp circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 25 | -- |
21 | Replace the turn signal lamp assembly. Refer to Parking and Turn Signal Lamp Replacement or Tail Lamp Replacement . Did you complete the replacement? |
Go to Step 25 | -- |
22 | Replace turn/hazard flasher. Refer to Hazard and Turn Signal Flasher Replacement . Did you complete the replacement? | Go to Step 25 | -- |
23 | Replace the lamp or the instrument cluster as necessary. Refer to Instrument Cluster Replacement in Instrument Panel, Gages and Console, or Instrument Cluster Bulb Replacement . Did you complete the replacement? | Go to Step 25 | -- |
24 | Replace the multifunction, turn signal and hazard switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column. Did you complete the replacement? | Go to Step 25 | -- |
25 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
