ABS Indicator

• If the system is OK, the ABS indicator goes off 2 seconds after turning the ignition switch ON (II) without starting the engine, and then comes on again and goes off 2 seconds later after starting the engine.

  This occurs because the ABS modulator-control unit is turned on by the IG2 power source.

• The ABS indicator comes on when the ABS modulator-control unit detects a problem in the system. However, even though the system is operating properly, the indicator will come on under these conditions:
  • Only the drive wheels rotate
  • One drive wheel is stuck
  • The vehicle goes into a spin
  • The ABS continues to operate for a long time
  • The vehicle is subjected to an electrical signal disturbance

To determine the actual cause of the problem, question the customer about the problem, taking these conditions into consideration.

• When a problem is detected and the ABS indicator comes on, there are cases when the indicator stays on until the ignition switch is turned OFF, and cases when the indicator goes off automatically when the system returns to normal.
  • DTC 61 or 62: The ABS indicator goes off automatically when the system returns to normal.
  • DTC 11, 13, 15,17, 31, 32, 33, 34, 35, 36, 37, 38, 54, 71, or 81: The ABS indicator stays on until the ignition switch is turned OFF whether or not the system returns to normal.
  • DTC 12, 14, 16, 18, 21, 22, 23, 24, 41, 42, 43, 44, 51, 52, or 53: The ABS indicator goes off when the vehicle is driven again and the system is OK after the ignition switch is turned from OFF to ON (II).
