Section 14 (Anti-Lock Brake System): Operation: Notes
WARNING: This page is about a different car, the 1994 Mitsubishi Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The RWAL control unit continuously monitors brakelight switch input, as well as wheel speed and "G"-force sensor input signals, to determine control of the modulator valve and ANTI-LOCK warning light. Control unit is located under center of instrument panel, behind "G"-force sensor.
If RWAL control unit detects a malfunction in the RWAL system, control unit will turn on ANTI-LOCK warning light by providing a ground circuit at terminal No. 8 of control unit. When a malfunction code is stored and ANTI-LOCK warning light is illuminated, control unit will disable anti-lock function. During this time, system will function as a normal hydraulic brake system. When system returns to normal, control unit will enable anti-lock function.
CAUTION:
See ANTI-LOCK BRAKE SAFETY PRECAUTIONS article in GENERAL INFORMATION.
