Probably both computers are faulty. Old age and vibrations crack the relay soldered joints inside the comuter (behind rear seat). Sometime invisible cracks, so resolder all relay connections to the board. Disconnect battery; remove rear seat (LHS - two pull-clips under front of seat)) and seat back; unbolt wires etc, unbolt steelwork & computer; open computer case; circuit board with copper strips to it has two black boxes (relays; remove this circuit board & resolder relay-to-circuit board joints. Check other circuit board for bulging capacitors & replace as required with same values. Probably cure all ills - cured all mine!

Your first option should be to check all the connections. Corrosion and moisture can set in if the cars left unused for any length of time. Check your fuses around the brake system; this could be a problem for grease losing, damage the axle in short time. Other posibility is one electricla switch or sensor bad.

The 4WS system is a fairly complex setup hence Toyota will probably charge an arm and a leg for fixing any fault on it (also it is a *** option).

There are five main components, main motor, backup motor, speed sensor, steering sensor and 4WS computer so it could be any of these, also add a possible wiring fault on top of that.

You can carry out a diagnostic test to interrogate the 4ws management fault code by bridging TC and E1 connections at the diagnostic plug (situated next to the top of the passenger front suspension strut in the engine bay). With these two connections shorted you should get a series of flashes from the 4WS light on the dash when you switch on the ignition. Each series of flashes represents a digit which can be looked up.

How do i disconnect the 4ws


Compare your rear knuckles to a non 4WS. You have to remove the steering extension shaft leading back there as well as the rear tie rods. The rear knuckles have to be locked so they don't steer. Might need to swap some of the components from a junkyard 88 89 90 91 Prelude.

MAZDA MX6 1993: 4WS & Fuel lights on


Usually there is a senser on your disk pad with the wire connect to the light, when the pad is too low, the senser touch the disk rotor and grounded, the light is on.

If you do not use the original disk pad from the dealer, the senser is not build in, when you put the disk pad, must put right and connect the wire right, otherwise it will go on. No harm at all. just one pad didn't right, the light will on.

I don’t know what pad you put in.

About the fuel light;

How long the light going on or just a little while?
