In the 1990-1996 it should be in the trunk underneath the speaker on the right side in that area (under some interior panels)
Take the fuse out or just unhook it from the modulator.
TCS communication line - ECM can not receive the information from "ABS actuator and electric unit (control unit)" continuously.Possible Causes:Harness or connectors (The CAN communication line is open orshorted.)ABS actuator and electric unit (control unit).Dead (Weak) battery
Master Cylinder for brake and clutch are located next to the ABS unit on the firewall of the driver side in the engine bay. Slave cylinder for clutch is located on the bottom of the transmission.
Follow the 2 brake lines that lead out of the master cylinder, they run to the ABS unit.
The ABS pump relay is intergrated into the EHCU (elecro-hydraulic control Unit) and it is not serviceable. If the ABS pump relay is defective, the entire control unit must be replaced.
under the bonnet
On a 1995 300zx N/A Coupe it is located behind the passenger seat under the plastic cover where the ABS assembly is. It is in a black box on top of the ABS unit under the black cover. There are two relays one has a raised tang on it that is the abs motor relay the other is the solenoid relay. Should be the same for 1990 to 1995 and maybe more and TT should be the same, do not know where the 2+2 relay is.
The fuse for the abs in a 90 300ZX non turbo is located in front of the drivers side wheel, in the fuse box(marking on the lid will tell you which one it is).. it should be a 20 amp fuse.
There could be something wrong with the ABS system and check the ABS sensors on all wheels. Also check the connections to the ABS unit and the traction control button.
The most common way is to remove the fuse itself for the ABS, your breaks will still work but the ABS feature will not run constantly and it will in turn operate without a dead battery. As far as a permanent solution I do not know for sure how to fix it, it is a somewhat common problem with the 300zx and power problems.
ECU stands for Engine Control Unit. It is present in every modern day vehicle. It takes in various sensor readings (like engine speed, fuel level, engine temperature etc) and controls the various systems (like ABS, Traction Control, Cruise Control etc) and indicators on the dashboard of the vehicle.
Anti-Lock Brakes (ABS) Description: Today, virtually all cars come with ABS as standard equipment or as an option. The typical ABS system includes wheel-speed sensors, a hydraulic control unit, and an electronic control unit. When you apply the brake pedal, the electronic control unit monitors and compares the signals from the wheel-speed sensors. If the electronic control unit senses rapid deceleration (impending lock-up) at a given wheel, the electronic control unit commands the hydraulic control unit to reduce hydraulic pressure to that wheel. This type of pressure limiting is similar to pumping the brake pedal, only much faster. Some pick-up trucks and cargo vans have rear-wheel only ABS to handle different braking needs under different loading conditions. This type of ABS system controls only the rear wheels and limits pressure to both of them when either is about to lock. Click here to view a detailed diagram of the brake system. Purpose: ABS was designed to help you maintain directional control during emergency stops and when road conditions are poor. By maintaining control, you have better chances of avoiding a crash. ABS is especially useful on wet and slippery roads. You should never pump the brake pedal on a car with ABS, since the system itself
