and Connector Repairs
in Wiring Systems. Did you find and correct the condition? |
Go to Step 20 | Go to Step 17 |
| 12 | Inspect for poor connections at the harness connector of the turn/headlamp/wiper switch. Refer to Testing for Intermittent Conditions and Poor Connections
and Connector Repairs
in Wiring Systems. Did you find and correct the condition? |
Go to Step 20 | Go to Step 18 |
| 13 | Inspect for poor connections at the harness connector of the body control module (BCM). Refer to Testing for Intermittent Conditions and Poor Connections
and Connector Repairs
in Wiring Systems. Did you find and correct the condition? |
Go to Step 20 | - |
| 14 | Repair an open or high resistance in the ground circuit of the inoperative lamp. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Did you complete the repair? |
Go to Step 20 | - |
| 15 | Repair an open, high resistance, or short to ground in the inoperative turn signal supply voltage circuit. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Did you complete the repair? |
Go to Step 20 | - |
| 16 | Repair an open or high resistance in the ground circuit of the turn signal/multifunction switch. Refer to Circuit Testing
and Wiring Repairs
in Wiring Systems. Did you complete the repair? |
Go to Step 20 | - |
| 17 | Replace the IPC. Refer to Control Module References
in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? |
Go to Step 20 | - |
| 18 | Replace the turn signal/multifunction switch. Refer to Multifunction, Turn Signal Switch Replacement
in Steering Wheel and Column. Did you complete the replacement? |
Go to Step 20 | - |
| 19 | Replace the BCM. Refer to Control Module References
in Computer/Integrating Systems 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? |
