ground HONDA CIVIC 2002 7.G Workshop Manual

Front Camber Inspection
Use commercially available computerized four wheel
alignment equipment to measure wheel alignment(caster, camber, toe, and turning angle). Follow the
equipment manufacturer's instructions.
Check the camber angle. lf the camber angle is not
within the specification, adjust the camber.
Front camber angle: 0"30' t 45'
Front Camber Adjustment
The front camber can be adjusted by exchanging one or
both of the damDer Dinch bolts with the smaller
diameter adjusting bolt(s). The difference between the
adjusting bolt diameter and the pinch bolt hole
diameter allows a small range of adjustment.

Raise the front of the vehicle, and support it with
safety stands in the proper location (see page 1-8).
Remove the front wheels.
Loosen the damper pinch nuts and bolts (A), and
adjust the camber by moving the bottom of the
damper within the range of the damper pinch bolt

Remove the front wheels.
Replace the damper pinch bolts with the adjusting
bolts (A), and adjust the camber angle.
NOTE: The camber angle can be adjusted up to t
15' (center of tolerance) by replacing one damper
pinch bolt with the adjusting bolt. The camber
angle can be adjusted up to a 30' by replacing both
upper and lower damper pinch bolts with the
adjusting bolts.

Reinstall the front wheels. Lower the front of the
vehicle to the ground, and bounce the vehicle

Check the camber angle. lf it is within the
specification, check the front toe. and adjust it if
necessary. lf it is not within the specification,
readjust, and recheck. lJ the camber angle cannot
be adjusted to the specification, check for bent or
damaged suspension components.

1. Remove the rear console, and disconnect theconnector (A)from the switch (B).
Check for continuity between the switch terminal
and body ground:

continuity.. With the brake lever down, there should be no
continuity.

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.

How to Clear ABS DTCs
Honda PGM Tester Method:
1. With the ignition switch OFF, connect the Honda
PGM Tester (A)to the l6Pdata link connector (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.
Cycling the lgnition Switch Method:
Clear the DTC by turning the ignition switch ON (ll) then
OFF at least 20 times.
