General Troubleshooting Information (cont'd)
How to Troubleshoot ABS DTCs
The troubleshooting flowchart procedures assume that
the cause of the oroblem is still Dresent and the ABS
indicator is still on. Following the flowchart when the
ABS 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. Ouestion the customer about the conditions when
the problem occured, and try to reproduce the
same conditions for troubleshooting. Find out
when the ABS indicator came on, such as during
ABS control, after ABS control, when the vehicle
was at a certain speed, etc.
2. When the ABS indicator does not come on during
the test-drive, but troubleshooting is done based on
the DTC, check for loose connectors. poor terminal
contact, etc., before you start troubleshooting.
3. After troubleshooting, clear the DTC,disconnect the
Honda PGM Tester. and test-drive the vehicle.
Make sure the ABS indicator does not come on.
How to Retrieve ABS DTCs
Honda PGM Tester Method:
1, Wjth the ignition switch OFF, connect the Honda
PGM Tester (A) to the 16P data link connector (DLC)
(B) under the driver's side of the dashboard.
19-32
2. Turn the ignition switch ON (ll), and follow the
prompts on the PGM Tester to display the DTC{S)
on the screen. After determining the DTC, refer to
the DTC Troubleshooting Index.
NOTE: See the Honda PGM Tester user's manual
for specific instructions.
Service Check Signal (SCS) Circuit Method:
1. With the ignition switch OFF, connect the Honda
PGM Tester (A) to the 16P data link connector (DLC)
(BI under the driver's side of the dashboard.
2. Short the SCS circuit to body ground using the
Honda PGM Tester.
3. Turn the ignition switch ON (ll).

4. The blinking frequency indicates the DTC. DTCS are
indicated by a series of long and short blinks. One
long blink equals 10 shon blinks. Add the long and
short blinks together to determine the DTC. After
determining the DTC, refer to the DTC
Troubleshooting Index.
NOTE:. lf the DTC is not memorized, the ABS indicator
will go off for 3.6 seconds, and then come back
on.. lf the ABS indicatorstays on, troubleshootfor"ABS indicator does not go off" (see step 1 onpage 19-53).
Th€ system will not indicate the DTC unless these
conditions are met:. The brake pedal is not pressed.. The ignition switch is turned ON {ll).. The SCS circuit is shorted to body ground before
the ignition switch is turned ON (ll).
Example ot DTC 15
Long blinkShort blinks{five timesl
Examole of DTC 22
Long blinks (two times)
Turn the ignition swltch OFF,
Disconnect the Honda PG M Tester from the DLC.

{B} under the driver's side of the dashboard.
Turn the ignition switch ON (ll), and clearthe
DTC(s) by following the screen prompts on the
PGM Tester.
NOTE: See the Honda PG l\4 Tester user's manual
for sDeclf ic instructions.
