Method of diagnosing a starter relay failure using synchronized state machine |
| 摘要 |
A method and electrical system for detecting and compensating for a failure in a starter circuit that comprises first and second relays in a circuit path to a starter motor of a vehicle. The method and system determine if at least one of the first or second relays is in a closed position when it should be in an open position and disables a vehicle starter operation if it is determined that at least one of the first or second relays is in the closed position when it should be in the open position. The vehicle starter operation could be a stop-start operation of the engine. |

1. A method of detecting and compensating for a failure in a starter circuit that comprises first and second relays in a circuit path between a battery and a starter motor of a vehicle, said method comprising:
monitoring the first and second relays in the circuit path to determine if at least one of the first or second relays is in a closed position when it should be in an open position; and disabling a vehicle starter operation if it is determined that at least one of the first or second relays is in the closed position when it should be in the open position. |
