Conditions for Setting the DTC

Action Taken When the DTC Sets
| • | The PCM disables the cruise control. |
| • | The PCM will not illuminate the malfunction indicator lamp (MIL). |
| • | The PCM will store conditions which were present when the DTC set as Fail Records data only. |
Conditions for Clearing the DTC
| • | The History DTC will clear after 40 consecutive warm-up cycles without a malfunction. |
| • | The DTC can be cleared by using the scan tool's Clear DTC Information function. |
