WARNING: Connecting jumper wire between incorrect DLC-1 terminal and chassis ground may cause damage and possible ABS malfunction. Ensure correct DLC-1 terminal is used before jumpering.

With ignition switch turned to OFF position, connect a jumper wire between DLC-1 terminal No. 13 and chassis ground. See Figure . Turn ignition switch to ON position (engine off). After ABS warning light illuminates for 3 seconds, ABS warning light will flash, indicating DTCs in memory. See Fig 1 . If any DTCs are present, see DIAGNOSTIC TROUBLE CODE IDENTIFICATION table. Perform appropriate diagnostic test. See DIAGNOSTIC TESTS . Clear codes after servicing. See CLEARING CODES .
