Hi Guys,
Found the following on a English site, outlines how to jumper the diagnostic ports for various tests, may be of help to someone out there.
Regards Lambo
The Soarer has a complete onboard diagnostic system that when run will show up most faults if you are having problems.
The following information is from the Lexus 'Repair Manual' for the SC400 and Steve Cheetham and is applicable for the Soarer V8 and Soarer TT, though some differences may apply. If you are unsure ask on the forum first.
There are two diagnostic points on the Soarer, one in the engine bay and one inside the cabin under the right side instrument panel.
The diagnostics connector in the engine bay (DLC1) is mainly used for engine adjustment.
The diagnostics connector in the cabin (DLC2) is used for diagnosis of data from the engine, automatic transmission, ABS, Aircon, Airbag, Traction Control and Cruise Control systems.
Connecting terminal E1 to other terminals selects different diagnosis modes. The location of terminals is on the label inside the diagnostics connector covers.
Engine and automatic transmission diagnostics can be run by placing a jumper in the engine diagnostics (data link) connector between E1 and TE1 terminals for normal mode
ABS, Aircon, AIrbag, Traction Control and Cruise Control diagnostics can be run by placing a jumper between E1 and TC.
Automatic transmission diagnostics can be run by placing a jumper between E1 and TT.
With the engine turned off a straightened up paper clip can be used as a jumper but must be inserted very deep in the terminals. In case of Soarer GT or LTD without the EMV screen, when the ignition is switched to 'on' error code/s will be displayed in the combination meter on the LCD screen that normally shows the time.
At first a Japanese message appears indicating the diagnostics mode and when the SCROLL button is pushed repeatedly, the diagnostic condition of the various elements including the engine ECU and transmission ECT will show as either Good or N/G (no good).
If N/G appears, wait for up to 2 minutes for the display of the actual numerical error code/s. If more than one error code is stored, all will be shown in succession with breaks between them.
Take a note of the error codes reported and ask on the forum

Engine and automatic transmission diagnostics can be run by placing a jumper in the engine diagnostics (data link) connector between E1 and TE2 terminals for test mode.
Compared to the normal mode, the test mode has high sensing ability to detect malfunctions such as poor contact, which are difficult to detect in the 'normal mode'.
It can also detect malfunctions in the starter signal circuit, the IDL contact signal of the the throttle position sensor, air conditioning signal and park/neutral position switch signal.
Test mode is normally used if in 'normal mode' you have a malfunction reported with one of the following error codes.
13, 21, 22, 24, 25, 26, 27, 28, 29, 35, 41, 42, 47, 71, 78.
Test mode will fill up the self diagnosis system.
To clear down the trouble codes you have to remove the EFI fuse (30A) from the fuse box in the engine bay for 10 seconds or more with the ignition switch OFF.
