Counting Codes

To represent a single digit of a 4 digit code, ABS warning light will flash at rate of .4 seconds with a pause of 1.2 seconds between digit codes. After all four digits have been displayed ABS warning light will flash for 1.2 seconds and will repeat that code.

To view additional codes, insert diagnostic jumper for 3 seconds and then remove jumper. Repeat this procedure to view all codes present. When all codes have been read, ABS warning light will flash on for 1.2 seconds and off for 1.2 seconds.
