The ALDL (Assembly Line Diagnostic Link) is a 10-way socket which allows communication with the ECU.
Locating the ALDL
LHD Cars
For the standard LHD car, the ALDL can be found plugged into a square black female plastic housing. This housing is under the dashboard within the passenger's side footwell (right side). Similarly for those LHD with aircon.
RHD Cars
For the standard RHD, the ALDL is in a similar housing again located in the passenger's footwell (left side). However, from the Service Notes drawing, it appears that it will be best found by opening the passenger glove box past the metal stop, exposing the wiring behind it. Owners have reported it may alternatively be found by exploring under the dash, behind the glove box without needing to open it. The RHD with aircon location is slightly higher up and probably needs the glove box swung down.
Communicating with the ECU
The dealer's diagnostic scanner (called a "Tech 1") can be plugged into the ALDL for digital fault code readout as well as "real time" diagnostics and sensor readings.
The good news is that now there is an alternative: ElanScan. This is a free program that does the same stuff as a Tech 1 with a laptop PC and an ALDL interface to connect the PC to the car. The program and information on making or buying an interface can be found at http://www.astb91.dsl.pipex.com/MountainChipMenu.html
