ANTI-LOCK BRAKE SYSTEM (ABS)
DTC INDICATION PATTERN
• The ABS indicator indicates the DTC by blinking a specified number of times. The indicator has two types of blinking, a long
blink and short blink. The long blink lasts for 1.3 seconds, the short blink lasts for 0.3 seconds. For example, when one long blink
is followed by two short blinks, the DTC is 1-2 (one long blink = 1 blink, plus two short blinks = 2 blinks).
• When the ABS control unit stores some DTCs, the ABS indicator shows the DTCs in the order from the lowest number to highest
number. For example, when the ABS indicator indicates DTC 1-2, then indicates DTC 2-3, two failures have occurred.
