Stop Start Enable Conditions
Stop Start is enabled during a normal driving cycle based on the entry conditions listed in the table below:
| Input | Stop-Start Inhibit Conditions | Rationale |
| ECT | 140 deg F < ECT > 230 deg F | Combustion Stability |
| BARO | BARO <= 20 in Hg (Altitude <= 10, 000 ft) | Minimum Air Charge |
| FRP at Idle | Fuel Rail Pressure (FRP) at Idle >= 45 Bar | Restart Combustion Stability |
| FRP w/Engine Off | FRP at engine off >= FRP at Idle with max drop of 5 Bar. If FRP at eng off drops below threshold, request pull-up | Restart Combustion Stability |
| Time Since Key-Start | 10 seconds | Oil Stabilization and Learn Closed Throttle |
| Max Crank Time | Max Crank Time should be min of 5 sec below limit to allow a shutdown | To avoid a possible max crank fault |
| Low Fuel Level | fuel level below 15% | Avoid starts on empty fuel tank |
| Purge complete | Canister Purge Valve no closed before end of pre stop period | Wait for purge to complete before pulling down engine |
| Adaptive Fuel Complete | Adaptive fuel learning not complete | If Adaptive fuel learning is in process, wait for it to complete before pull down |
