Circuit description: Notes
While the engine is being cranked, the starter operation signal is also transmitted to the STSW terminal (for models without smart entry & start system) or STSW2 terminal (for models with smart entry & start system) of the engine control computer. The starter operating signal is primarily used for engine control during startup.
For models with smart entry & start system, when the engine control computer detects engine startup condition during engine cranking, the engine control computer drives the ST CUT relay and stops starter operation.
DTC DETECTION CONDITION
| DTC No. | DTC detection conditions | Suspected parts |
|---|---|---|
| P0512 | The starter signal continues to be input for 30 seconds or more after engine start. (1 trips detection logic) |
|
| P0616 | No starter signal is input after engine start. (1 trips detection logic) |
|
| P0617 | The starter signal continues to be input after engine start. (1 trips detection logic) |
|
| P081A | Short circuit is detected in the ST cut relay circuit. (1 trips detection logic) |
