Following the unique engine code is the displacement, which in this case, is 3.8L, which creates the ‘VR38. ‘ From there, the ‘D’ refers to the dual overhead cam (or DOHC), ‘E’ represents ‘Electronic Fuel Injection,’ and ‘TT’ concludes the name with ‘Twin Turbo.
Can you remove the HICAS light from the ECU?
This disables the HICAS ecu from reporting any problems. Altesrnatively you could also just remove the light bulb behind the cluster for the HICAS light but thats not as good as an idea because sometimes the HICAS lamp is used by the ECU in conjunction with other lamps to indicate other problems.
What should I look for in a HICAS steering system?
Suddenly you’re swerving wildly about battling the HICAS system for control of the rear end. It’s a complete disaster and frankly a little dangerous. For even better control and handling look over this guide on Sway Bars, Understeer and Oversteer.
Is there a way to remove the HICAS?
There are a few quick and simple solutions, that effectively lock out the HICAS but don’t remove the weight, such as the Tomei kit which handles it electronically. There’s also a number of kits that mechanically lock out the system by replacing the rear steering rack with a solid bar instead. This guide is how to completely remove the system.

What kind of steering system does a HICAS have?
Earlier HICAS versions used hydraulics to steer the rear wheels. The hydraulic system was powered by the power steering pump and used speed sensors to determine how much and in which direction to steer the rear wheels. Later versions, called Super HICAS, moved to an electric actuator for the rear steering rack, making the system much lighter.
What was the difference between the HICAS and the Super HICAS?
Later versions, called Super HICAS, moved to an electric actuator for the rear steering rack, making the system much lighter. The Super HICAS system also used its own computer to control the system instead of speed sensors.
