If your DieHard Remote Starter won't jump start your car, first ensure that the Jump Start switch is turned ON. Then, check for a poor connection to the battery and frame, making sure the connection points are clean. Verify the battery charge status by pressing the Select button on the front of the unit. If the issue persists, the vehicle’s battery might be defective and should be checked.
