Typical Scan Tool Data
WARNING: This page is about a different car, the 2008 GMC Yukon and 2008 Chevrolet Tahoe. However, it is still accessible from the selected car via links, so may be relevant.
Autostop Inhibit Reasons

DTC P0C2B or P2797 set OR ECM Ambient Air Temperature less than 10°C (50°F)1 |
| Aux. Trans. Pump With ECM Ambient Air Temperature 10°C (50°F) - 15°C (59°F)1 |
DTC P0C2B or P2797 set OR TFT less than 35°C (95°F) or greater than 95°C (203°F) |
| Aux. Trans. Pump With ECM Ambient Air Temperature 15°C (59°F) - 20° (68°F)1 |
DTC P0C2B or P2797 set OR TFT less than 25°C (77°F) or greater than 95°C (203°F) |
| Aux. Trans. Pump With ECM Ambient Air Temperature greater than 20° (68°F)1 |
DTC P0C2B or P2797 set TFT less than 20°C (68°F) or greater than 95°C (203°F) |
| Drvr Axle Torque Request | Depression of the accelerator pedal has exceeded the torque capability for electric-only or EV Mode propulsion |
| ECM Request | ECM DTC testing in progress or ECM DTCs present |
| ECT - High Limit | ECT 110°C (230°F) or greater 2 Autostop if cools down to 90°C (194°F) once high temperature limit has been reached. |
| ECT - Low Limit With ECM Ambient Air Temperature 10°C (50°F) - 20°C (68°F)1 |
ECT less than 68°C (154°F) 2 Autostart if cools down to 60°C (140°F) once high temperature limit has been reached |
| ECT - Low Limit With ECM Ambient Air Temperature greater than 20°C (68°F)1 |
ECT less than 49°C (120°F) 2 Autostart if cools down to 44°C (111°F) |
| Hood Position | Open or faulted |
| Hybrid Batt. Pack Voltage | 250V or less 2 When Autostop limit has been achieved, Autostart if voltage drops to 200V |
| Hybrid Batt. Pack Power | 15kW or less Power is dependent upon battery temperature. Observe Hybrid Battery Temperature parameters when Hybrid Batt. Pack Power inhibits Autostop. 2 When Autostop limit has been achieved, Autostart if power drops to 12kW |
| Hybrid Battery SOC | 50% or less 2 When Autostop limit has been achieved, Autostart if SOC drops to 46% |
| ICE Run Time With ECM Ambient Air Temperature 10°C (50°F) - 15°C (59°F)1 |
Less than 20 seconds since ignition crank |
| ICE Run Time With ECM Ambient Air Temperature greater than 15°C (59°F)1 |
Less than 5 seconds since ignition crank |
| Ignition Crank | Ignition key not in RUN - engine remote started |
| IMS Range | Gear Selector in Reverse or Manual |
| Inverter Temperature | Greater than 65°C (149°F) 2 When Autostop limit has been achieved, Autostart at 70°C (158°F) |
| Min. Hybrid Batt. Module Voltage | The minimum hybrid battery module pair voltage is less than 14 volts. 2 When Autostop limit has been achieved, Autostart if voltage drops to 12V. |
| Motor Temperature | Greater than 165°C (329°F) 2 When Autostop limit has been achieved, Autostart at 170°C (338°F) |
| Run/Crank Mode | SDGM Power mode is not in RUN |
| 1 The HPCM monitors the ECM Ambient Air Temperature parameter to determine outside temperature. the ECM will default to 0°C (32°F) ambient air temperature if an IAT sensor DTC is present. | |
Hybrid Battery Temperature

|---|---|
| Hybrid Batt Min Cell Temp | Less than 10°C (50°F) |
| Hybrid Batt Max Cell Temp | Greater than 47°C (116°F) |
