Abstract: A diagnostics unit (10) for detecting a noise, vibration, harshness (NVH) type fault observed by a user of a vehicle (90). The diagnostics unit (10) comprising: a stud type attachment means (20) for rigidly attaching the diagnostics unit (10) to a test component (30) of the vehicle (90), for example a transfer case (30). The diagnostics unit (10) also comprises an accelerometer (28a, 28b) for detecting a force of acceleration in at least one axial direction (‘X’). A power source (27) is provided within the diagnostics unit (10) along with a Bluetooth® data transmitter (25) for transmitting data gathered by the accelerometer (28a, 28b) of the diagnostics unit (10) to a computing device (50), such as a lap-top disposed within the vehicle (90). The data is analysed by the lap-top (50) to identify which component of the transfer case (30) (for example, gear, chain, bearing) is faulty.

Abstract: A motor vehicle diagnostics apparatus (110, 152) having a diagnostics unit connectable in-line in a motor vehicle control system between first and second components (171, 172), the apparatus (110, 152) being operable to detect by means of the diagnostics unit (110) one or more electrical signals generated by the first component (171) for application to the second component (172) and to provide an output in response to the detected signals.
