Displaying & Reading Trouble Codes

Indicator Check





- When the ignition switch is turned on, check that the ABS Service Reminder Indicator (SRI) goes ON for 6 seconds.

- If the SRI is not illuminated immediately after ignition on, the ABS fail safe relay may be at fault.

SRI Code Check

- With the ignition switch turned ON and "L" terminal of data link connector shorted to ground, diagnostic trouble code No. can be checked, if faults are detected, with reading of Service Reminder Indicator (SRI) lamp flash.





1. Ground the "L" terminal (Pin No. 15) of data link connector with extension wire, otherwise fault code cannot be accessed.
2. Turn the ignition switch ON.





3. SRI lamp will illuminates for 2 seconds and followed by 3 seconds illumination meaning "Check-in" signal then read the following "Diagnostic trouble code".
4. The first digit of Diagnostic trouble code is determined by the number of long flashes (1.5 seconds) and after the following 2 seconds break, the second digit is determined by the number of short flashes (0.5 seconds).
5. Once the SRI lamp flashing is completed, next active trouble code or history trouble code stored at ABS Control Module (ABSCM) will be followed after 3 sec. break while the "L" terminal is grounded or the ignition switch is ON.





6. Diagnostic Trouble code will be retained in the ABSCM until the ignition has been switched ON and the vehicle speed exceeded 8km/h 20 times.

Connector Check





1. Remove the battery negative (-) terminal.
2. Disconnect the connectors and check the terminals follow the troubleshooting procedure.

NOTE
When you check terminals, be sure to use a small enough probe which will not damage the connector terminals.
