This is a TRAC and ABS system technical training article from Lexus, it shows the Toyota Supra (and Camry) Traction Control System (TRAC), ABS system and how they all work together with the ECU’s.

These documents can give further troubleshooting steps to the service manual and give a better understanding of the system in general.

2005 – IS300 Service Manual

Thought I’d had these posted but realised I hadn’t, this is the 2005 IS300 workshop manual pages. These come in handy for the VVTi guys due to the VVTi head torque and specs, most apply to the 2JZGE and 2JZGTE VVTi figures.

Most of these documents are applicable to the J-SPEC and Europe-SPEC supras. There might be differences to driving side, wiring and some features and functions.

Cleaning 2JZ VVTi Oil Control Valve (OCV)

This is a guide to cleaning the VVTi Oil Control Valve (OCV) and filter on the 2JZGTE or 2JZGE VVTi engine. This is the valve the controls the oil pressure sent to the VVTi intake cam gear assembly. This can be done as preventive maintenance, to replace with new components or if there are error codes. I’ve seen various forums that mention code 59 for supra and P1329 for IS300/Aristo which may be cleared by cleaning the OCV if there are issues with the VVTi system.

IS300 Wiring Diagrams

Attached are both the wiring diagrams for the 2001 and also 2002-2005 Lexus IS300.

Disclaimer – I don’t take any responsibility for these diagrams, these do seem to be the factory wiring diagrams but I always like to double check / cross reference any wiring. Also I do not own a IS300 and can’t confirm these diagrams.

2JZGTE VVTi Coil and Igniter Diagram

After seeing an incorrect 2jzgte vvti coil and wiring diagram online I quickly put a simple one together that will come in handy! This is useful for working on the coils and igniter, please refer to more in-depth wiring diagrams when tracing wiring or working on more in depth wiring problems such as the VVTi wiring diargams you can find HERE.

Yes the coils are numbered 1,3,2!!!

I have confirmed this with IS300 workshop manual, Japanese wiring diagrams and also my own car.

IS300 2JZGTE VVTi Swap Manual

After reponding to a question on here I figured it made sense to host a link of this IS300 2JZGTE VVTi swap manual. Although I didn’t do the swap personally or own an IS300 I think it’s a great swap write up that applies to most late model 2JZGTE VVTi swaps and engine swaps in general.

The document also contains information I have provided over the years on supraforums and has pictures I have provided.

A big thanks to Indirocz28 from http://my.is/forums/.

As a side note please don’t reference the pinouts in the manual, if the author ever updates the word document with my new pinouts I will re-upload.

***UPDATE – IS300 ECU pinouts can be found here – http://www.2jzgarage.com/2013/04/lexus-is300-ecu-pinouts/ and IS300 Wiring Diagrams can be found here – http://www.2jzgarage.com/2013/04/is300-wiring-diagrams/
