Vehicle: 1993 Mitsubishi Expo 2.4 L4 GAS
General Malfunction Diagnosis
Except Pickup
Problems related to the Anti-Lock Brake System (ABS) can generally be classified as electrical or hydraulic.
For problems in the electrical system, a self-diagnostic function is built into the Electronic Control Unit (ECU), allowing the ABS warning lamp to illuminate as a warning to the driver in the event of an abnormality. In this instance, inspections can be performed with a voltmeter, Multi-Use Tester (MUT), oscilloscope or the ABS warning lamp.
Problems with the hydraulic system can be located in the same manner as ordinary brakes. It...
