ABS Indicator

• If the system is OK, the ABS indicator comes on, then goes off 2 seconds after turning the ignition switch ON (II).
• 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 can 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, 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, 51, 52, or 53: The ABS indicator goes off after the ignition switch is turned OFF and then back ON (II), the vehicle is driven, and the system is OK.
