ABS/TCS Components
General Troubleshooting Information (cont'd)
How to Troubleshoot DTCs
The troubleshooting flowchart procedures assume that
the cause of the problem is still present and the ABS
and/or TCS indicator is still on. Following the flowchart
when the ABS and/or TCS indicator does not come on
can result in incorrect diagnosis.
The connector illustrations show the female terminal
connectors with a single outline and the male terminal
connectors with a double outline.
1. Question the customer about the conditions when
the problem occured, and try to reproduce the
same conditions for troubleshooting. Find out
when the ABS and/or TCS indicator came on, such
as during ABS control, after ABS control, when
vehicle speed was at a certain speed, etc.
2. When the ABS or TCS indicator does not come on
during 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 or repairs are done, clear the
DTC, and test-drive the vehicle. Make sure the ABS
and TCS indicators do not come on.

Troubleshooting Index.

instructions.
Service Check Signal (SCS) Circuit Method
1. With the ignition switch OFF, connect the HDS to
the 16P Data Link Connector (DLC) (A) under the
driver's side of the dashboard.
2. Short the SCS circuit to body ground using the HDS.
3. Turn the ignition switch ON (II) without pressing the
brake pedal.
NOTE: If the brake pedal is pressed when turning
the ignition switch ON (II), the system shifts to the
DTC clearing mode.
