Reading and Clearing Diagnostic Trouble Codes

When on-board diagnosis of the ABS control module detects a problem, the information (up to a maximum of three) will be stored in the EEP ROM as a trouble code. When there are more than three, the most recent three will be stored. (Stored codes will stay in memory until they are cleared.)

CALLING UP A TROUBLE CODE
1) Take out ABS diagnosis connector from side of driver's seat heater unit.
2) Turn ignition switch OFF.
3) Connect ABS diagnosis connector terminal 6 to diagnosis terminal.
4) Turn ignition switch ON.





5) ABS warning light is set in the diagnostic mode and blinks to identify trouble code.
6) After the start code (11) is shown, the trouble codes will be shown in order of the last information first.
These repeat for a maximum of 5 minutes.

NOTE: When there are no trouble codes in memory, only the start code (11) in shown.

CLEARING MEMORY





1) After calling up a trouble code, disconnect ABS diagnosis connector terminal 6 from diagnosis terminal.





2) Repeat 3 times within approximately 12 seconds; connecting and disconnecting terminal 2 and diagnosis terminal for at least 0.02 seconds each time.

NOTE: After diagnostics is completed, make sure to clear memory. Make sure only start code (11) is shown after memory is cleared.
