In-vehicle wiring harness with multiple adaptors for an on-board diagnostic connector
View Patent ↗An embodiment provides a wiring harness that connects a telematics device to a host vehicle. One embodiment of the wiring harness may include: 1) a cable featuring a plurality of wires; 2) a first connector featuring a snap-on adaptor that attaches to a connector core with a pin configuration that mates with a diagnostic scan tool; 3) a second connector that connects to an in-vehicle diagnostic system; and 4) a third connector that connects to the telematics device. A wiring kit embodiment and method embodiments for coupling a telematics device to a host vehicle are also disclosed.
1. A method for collecting data relating to a vehicle having a telematics unit which receives at least a portion of the data from an engine control unit, the method comprising:
detecting downloading of the data, wherein the data is downloaded through an on-board diagnostic connector; and
discontinuing receipt of the data by the telematics unit when the downloading is detected.
2. The method of claim 1 wherein the vehicle has an onboard diagnostic connector communicating with the engine control unit and wherein said downloading comprises coupling a scan tool to the onboard diagnostic connector.
3. The method of claim 2 further comprising:
decoupling the scan tool from the onboard diagnostic connector after a desired amount of data has been downloaded to the scan tool; and
enabling the telematics unit to receive data from the engine control unit.
4. A telematics unit having instructions stored thereon which when executed:
receive data from an engine control unit communicating therewith;
detect downloading of data to a scan tool communicating with the engine control unit; and
discontinue receipt of the data upon the detecting the downloading of diagnostic data to the scan tool.
5. A telematics unit comprising:
means for receiving data transmitted by an engine control unit;
means for detecting downloading of data from the engine control unit to a scan tool; and
means for discontinuing receipt of the engine control unit transmitted data by the means for receiving during the downloading of the data to the scan tool.
6. A computer readable medium having instructions stored thereon which when executed by a processor, cause the processor to:
enable a telematics unit to receive data from an engine control unit;
detect when the engine control unit is downloading data to a scan tool; and
discontinue receipt of the engine control unit transmitted data by the telematics unit during the downloading of data from the engine control unit to the scan tool.
