Conditions for Clearing the MIL/DTC
WARNING: This page is about a different variant/trim than selected.
- The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
- A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
- A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
- Clear the MIL and the DTC with a scan tool.

IMPORTANT:
The ignition 1 voltage circuit is spliced to other components of the vehicle. Test the spliced ignition 1 voltage circuits and components for a short to ground. Refer to the following procedures:Did you find and correct the condition? |
Go to Step 16 | - |
| 13 | Repair the high resistance or an open in the SC intercooler pump relay coil ignition 1 voltage supply circuit. Did you complete the repair? |
Go to Step 16 | - |
| 14 | Replace the SC intercooler pump relay. Did you complete the replacement? |
Go to Step 16 | - |
| 15 | Replace the PCM. Refer to Control Module References
for replacement, setup, and programming. Did you complete the replacement? |
