Civic LX Sedan L4-1590cc 1.6L SOHC MFI (1998)
ABS Light: Description and Operation
1. The Anti-Lock Brake System (ABS) indicator light comes on when the ABS control unit detects a problem in the system. However, even though
the system is normal, the ABS indicator light can come on, too, under the following conditions:
-
Signal disturbance
-
Wheel spin
-
Only drive wheels rotate
-
Battery voltage fluctuates
2. When a problem is detected and the ABS indicator light comes on, the indicator light can stay on until the ignition switch is turned off, or it can
automatically go off, depending on the mode.
-
Light stays on until the ignition switch is turned off: When the system is in the system down mode.
-
Light automatically goes off: When the system is in the control inhibition mode.
3. The ABS indicator light stays on when the system is reactivated without erasing the Diagnostic Trouble Code (DTC), but it goes off after starting
the vehicle. When the wheel sensor system is faulty and the ABS indicator light comes on, the algorithm of the system automatically turns off the
ABS indicator light after the wheel speed signal returns to the normal speed. Also, when the DTC is erased, the CPU is reset and the ABS
indicator light goes off when the system checked out normal by the initial diagnosis. Therefore, test-drive the vehicle after servicing the wheel
sensor system, and be sure that the ABS indicator light does not come on.
4. When the ABS control unit outputs battery voltage to gauge assembly, the ABS indicator light goes off.
