An improved hand held starting/charging system tester. According to one aspect of the present invention, the portable handheld tester includes a connector to which various test cables can be removably connected to the tester. Detection circuitry within the tester determines which of several types of test cable is connected to the tester before testing. According to another aspect of the present invention, the portable handheld tester includes an improved user interface that permits a user to review test data from previously performed tests and further permits a user to either skip a previously performed test (thereby retaining the previously collected data for that test) or re-do the test (thereby collecting new data for that test). According to yet another aspect of the present invention, the portable handheld tester that performs a more complete set of tests of the starting/charging system.

A single input having multiple functions is provided. The single input having multiple functions may be used on off-board tools. In accordance with one embodiment, an off-board tool having a read/scroll actuator is provided. The read/scroll actuator, upon being actuated, performs either a read function or a scroll function. Another embodiment of an off-board tool having a display and capable of receiving information is provided. The off-board tool includes a contextual actuator having a first and a second mode. Actuation of the actuator in the first mode effectuates retrieval of information. Actuation of the actuator in the second mode effectuates display of at least a portion of the retrieved information. In accordance with another embodiment, an off-board device is provided. The off-board tool includes a display, read logic, scroll logic and a read/scroll actuator. Another embodiment of an off-board tool includes a display, a read means, a scroll means and a read/scroll means.

A diagnostic tool and method are provided wherein the diagnostic tool can function as an inspection tool and a scan tool. The diagnostic tool determines if it is authorized for an inspection and then functions as an inspection tool and does not allow the scan tool function until the inspection is completed or voided. A software of the diagnostic tool includes a shared code, an inspection tool mode and a scan tool mode. The scan tool code and the inspection code are not shared so that updating of one code does not affect the code of the other.

Exemplary embodiments of off-board tools (OBTS) may be used in vehicle inspection maintenance programs are provided. The OBT may include a processor, vehicle communication circuitry for linking to a vehicle diagnostic system, host interface circuitry for communicating with a host computer, and voltage determination circuitry for measuring a voltage through the vehicle diagnostic system. The OBT may include logic for storing a communications protocol used to link with a vehicle diagnostic system that is preferably used for re-establishing dropped communications links. In addition, the OBT may contain logic for testing at least one component of a starting and/or charging system of a vehicle. Still other embodiments may include logic for sending unsolicited messages to a host computer. Additional embodiments may include logic for determining the minimum number of messages that must be received by an OBT.
摘要:
An improved scan tool, e.g., for OBD II, for use with vehicle computer networks. The improved scan tool determines the proper protocol to use to communicate with a vehicle computer network. The proper protocol is determined by requesting information from the vehicle computer network using a plurality of protocols and selecting the protocol that returns the most pieces of information. In addition, the improved scan tool determines a communications drop-out with one or more modules and automatically recovers from a the communications drop-out.
