Initial Inspection and Diagnostic Overview

ABS Indicator Light Location:

The following is a list of problems and solutions related to the illumination of the ABS indicator light:

1. The ABS indicator light can illuminate due to certain temporary driving conditions. When the ABS indicator light illuminates, the ABS control unit memorizes the diagnostic trouble code (DTC) under certain conditions. The following is a list of driving conditions that can cause the ABS indicator light to illuminate. For descriptions of the DTC's referred to below, DTC List - Brakes and Traction Control
- The tire(s) adhesion is lost due to excessive cornering speed. DTC: 5, 5-4, 5-8.
- The vehicle loses traction when starting from a stuck condition on a muddy, snowy, or sandy road. DTC: 4-1,4-2,4-4,4-8.
- When the parking brake is applied for more than 30 seconds while the vehicle is being driven. DTC: 2-1.
- The vehicle is driven on an extremely rough road.

NOTE: The ABS is OK if the ABS indicator light goes OFF after the engine is restarted.

2. If you receive a customer's report that the ABS indicator light sometimes comes on, check the system using the ALB checker to confirm whether there is any trouble in the system. Function Test
3. The ABS indicator light will come ON and the ABS control unit will memorize a DTC when there is insufficient battery voltage to the ABS control unit. An example would be when the battery is so weak that the car must be jump-started. After the battery is sufficiently recharged, the ABS indicator light will work normally after the engine is stopped and restarted. However, after recharging the battery, the DTC must be cleared from the ABS control unit's memory by disconnecting the ABS B2 (15 A) fuse in the under-hood fuse/relay box for at least three seconds.
