Codes 11-51

Turn ignition on. Remove short pin from Data Link Connector (DLC) No. 1. See Fig 1. Connect jumper wire between terminals Tc and E1 of DLC No. 1 (or DLC No. 2).

Light Flashes Quickly (4 Times Per Second) - This is called "normal" code - system is normal (no codes are stored).
Codes Are Flashed

If codes are stored, the light will flash a 2-digit code (example of Code 23: FLASH, FLASH, pause, FLASH, FLASH, FLASH). If more than one code is stored, there will be a 2.5-second pause between each code. After all codes are flashed, a 4-second pause will occur, then all codes will repeat. For code interpretation, see INTERPRETING CODES. After servicing, clear codes. See CLEARING CODES.

NOTE: Ensure battery is in good condition and is fully charged. While diagnosing speed sensors, brake system functions as a standard system. If codes cannot be retrieved, perform Ts TERMINAL CIRCUIT test. See CIRCUIT TESTING. If problem remains, replace ABS ECU.
