General Troubleshooting Information (cont’d)

The troubleshooting flowchart procedures assume that
the cause of the problem is still present 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. Question 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 and test-drive

the vehicle. Make sure the ABS indicator do not
come on.

1. With the ignition OFF, connect the HDS to the 16P

data link connector (DLC) (A) located under the
driver’s side of the dashboard.

2. Turn the ignition ON (II), and follow the prompts on

the HDS to display the DTC(s) on the screen. After
determining the DTC, refer to the DTC
Troubleshooting Index.

NOTE: See the HDS help menu for specific
instructions.

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.

How to Clear DTCs

HDS (Honda Diagnostic System) Method

Service Check Signal (SCS) Circuit Method

19-43

Example of DTC 15

OFF

Long blink

Short blinks
(5 times)

OFF

Example of DTC 22

Long blinks (2 times)

Short blinks
(2 times)

4. The blinking frenquency indicates the DTC. DTCs

are indicated by a series of long and short blinks.
One long blink equals 10 short blinks. Add the long
and short blinks together to determine the DTC.
After determining the DTC, refer to the DTC
Troubleshooting Index.

NOTE: If the DTC is not memorized, the ABS
indicator will go off for 3.6 seconds, and then come
back on.

The system will not indicate the DTC unless these
conditions are met:

• The brake pedal is not pressed.
• The ignition switch is turned ON (II).
• The engine is stopped.
• The SCS circuit is shorted to body ground before

the ignition switch is turned ON (II).

5. Turn the ignition switch OFF.

6. Disconnect the HDS from the DLC.

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. Turn the ignition switch ON (II), and clear the

DTC(s) by following the screen prompts on the HDS.

NOTE: See the HDS help menu for specific
instructions.

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. Press the brake pedal.

4. Turn the ignition switch ON (II) while keeping the

brake pedal pressed.

5. After the ABS indicator goes off, release the brake

pedal.

6. After the ABS indicator comes on, press the brake

pedal again.

7. After the ABS indicator goes off, release the brake

pedal again.

You cannot clear the DTC unless these conditions
are met:

• The vehicle speed is 6 mph (10 km/h) or less.
• The SCS circuit is shorted to body ground before

the ignition switch is turned ON (II).

• The brake pedal is pressed before the ignition

switch is turned ON (II).

8. After a few seconds, the ABS indicator blinks twice

and the DTC is cleared. If the indicator does not
blink twice, repeat steps 1 thru 7. If the ABS
indicator stays on after it blinks twice, check the
DTC, because a problem was detected during initial
diagnosis before shifting to DTC clearing mode.

9. Turn the ignition switch OFF.

10. Disconnect the HDS from the DLC.
