DIAGNOSTIC TROUBLE CODES CHECKWhen Using the ABS Warning Light
1. Use the special tool (diagnostic trouble code check harness) to ground the terminal (1) of the data link connector.
2. Take a reading of the diagnostic trouble code from the flashing of the ABS warning light.
NOTE: Diagnostic trouble code No. 16 can be output when the ABS system fails because of a battery surge.
