H o w t o Troubleshoot ABS DTCs
The troubleshooting flowchart procedures assume that
the cause of the p r o b l e m is still present and the ABS
indicator is still o n . Following the flowchart w h e n the
ABS indicator does not come on can result in incorrect
diagnosis.
The connector illustrations show the female terminal
connectors w i t h a single outline and the male t e r m i n a l
connectors w i t h a double outline.
1. Question the customer about the conditions w h e n
the problem occured, and try to reproduce the
same conditions for troubleshooting. Find out
w h e n the ABS indicator came o n , such as d u r i n g
initial diagnosis, during ABS control, after ABS
control, w h e n vehicle speed w a s at a certain speed,
etc.
2. When the ABS indicator does not come on d u r i n g
the test-drive, but troubleshooting is done based
on the DTC, check for loose connectors, poor
contact of the terminals, etc. before you start
troubleshooting.
3. After troubleshooting, clear the DTC, and test-drive
the vehicle. Make sure the ABS indicator does not
come on.
