Defender 90 (LD) V8-4.0L (1997)
Information relating to the wiring and pin locations for the multi-function unit in Discovery vehicles is difficult to determine. In an effort to assist
technicians in the pursuit of problems which may be related to multi-function units, a series of tables have been developed by John Thomas of LRU to
assist in determining the root of the difficulty.
RESOLUTION:
TESTING OF UNIT
Refer to the ETM for the model year in question for detailed wiring diagrams associated with the MFU. There is a specific "self-diagnostic" function
performed by the MFU. Back-probing the MFU connector using the information supplied in the attachments to this TIB may be a useful method to help
determine the operation of the various MFU functions.
