System Indicators

If the system is okay, the ABS indicator goes off once after turning the ignition switch ON (II) without starting the engine, and then come on again and go off several seconds later after starting the engine. This occurs because the ABS control unit is turned on by the IG2 power source. The ABS indicator or ABS system indicator comes on when the ABS control unit detects a problem in the system. The ABS indicator or ABS system indicator will also come on under these conditions, even though the system is operating properly:

• The vehicle goes into a spin.
• The ABS continues to operate for a long time.
• The vehicle is subjected to an electrical signal disturbance.
• Only drive wheels rotate.
• One drive wheel is stuck.

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. For DTC 61, the indicator goes off automatically when the system returns to normal. For all other codes, the indicator stays on until the ignition switch is turned OFF.
• For DTCs 11, 13, 15, 17, 31, 32, 33, 34, 35, 36, 37, 38 and 54 or 81: The ABS indicator stays on until the ignition switch is turned OFF whether or not the system returns to normal.
• For DTCs 12, 14, 16, 18, 21, 51, 52 or 53: The ABS indicator goes off when the vehicle is driven again and the system is okay after the ignition switch is turned from OFF to ON (II).
