INFORMATION DISPLAY
SEL/RESET BUTTON
The maintenance minder is an important feature of the information display. Based on engine and transmission
operating conditions, the Acura CSX’s onboard computer (ECM/PCM) calculates the remaining engine oil and the
automatic transmission fluid life. The system also displays the remaining engine oil life along with the code(s) for
other scheduled maintenance items needing service.

1. The remaining engine oil life (A) is shown as apercentage on the information display. To see the
current engine oil life, turn the ignition switch to
ON (II), then push and release the SEL/RESET
button repeatedly until the engine oil life displays.
2. When the ignition switch is ON (II), and the remaining engine oil life is 6 % to 15 %, the
remaining engine oil life (A) and other scheduled
maintenance item(s) needing service are displayed.
The maintenance minder indicator (B) also comes
on when the engine oil life is 15 % or less. To
cancel the display and the indicator, press SEL/
RESET button.
 Complete list of maintenance main items (C) (see page 3-7).
 Complete list of maintenance sub items (D) (see page 3-8). 3. When the ignition switch is ON (II), and the
remaining engine oil life is 1 % to 5 %, the message
‘‘SERVICE’’ (A) is displayed along with engine oil
life and the same maintenance item code(s).
4. When the ignition switch is ON (II), and the remaining engine oil life is 0 %, the engine oil life
indicator (A) blinks. Pressing SEL/RESET button
cancels the display, but the maintenance minder
indicator stays on.
5. If the indicated maintenance is not done, the engine oil life indicator shows a negative mileage, for
example ‘‘ 10,’’ on the display. If the negative
mileage is between 0 and 9, the indicator is
displayed for only a few seconds when the ignition
switch is turned to ON (II). The negative mileage
remains displayed after the vehicle is driven more
than 10 km after 0 % oil life is reached, and the
display cannot be canceled.
This means the indicated maintenance item(s)
should have been done more than 10 km ago.

General Information (cont’d)
NOTE:
 The vehicle must be stopped to reset the display.
 If a required service is done and the display is not reset, or the maintenance display is reset without
doing the service, the system will not show the
proper maintenance timing. This can lead to serious
mechanical problems because there will be no
accurate record of when the required maintenance is
needed.
 The engine oil life and the maintenance item(s) can be only reset independently with the HDS.
1. Turn the ignition switch to ON (II).
2. Push and release the SEL/RESET button repeatedly until the engine oil life indicator is displayed.
3. Press and hold the SEL/RESET button for about 10 seconds. The engine oil life indicator and the
maintenance item code(s) will blink, then release
the button.
NOTE: If you are resetting the display when the
engine oil life is more than 15 %, make sure the
maintenance item(s) requiring service are done
before resetting the display.
4. Press and hold the SEL/RESET button for another 5 seconds. The maintenance item code(s) will
disappear, and the engine oil life will reset to ‘‘100’’. 1. Connect the Honda Diagnostic System (HDS) to the
data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module/powertrain control
module (ECM/PCM). If it doesn’t communicate,
troubleshoot the DLC circuit (see page 11-6).
4. Select GAUGES in the BODY ELECTRICAL with the HDS.
5. Select ADJUSTMENT in the GAUGES with the HDS.
6. Select SERVICE REMINDER in the ADJUSTMENT with the HDS.
7. Select RESET in the SERVICE REMINDER with the HDS.
8. Select the individual maintenance item you wish to reset.

1. Remove the valves (see page 6-54).
2. Measure the valve in these areas. 1. Remove the valves (see page 6-54). 2. Slide the valve out of its guide about 10 mm(0.39 in.), then measure the stem-to-guide
clearance with a dial indicator while rocking the
stem in the direction of normal thrust (wobble
method). If the measurement exceeds the service limit, recheck it using a new valve.
 If the measurement is now within the service limit, reassemble using a new valve.
 If the measurement with a new valve still exceeds the service limit, go to step 3.
3. Subtract the O.D. of the valve stem, measured with a micrometer, from the I.D. of the valve guide,
measured with an inside micrometer or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide.
The difference between the largest guide
measurement and the smallest stem measurement
should not exceed the service limit.

Connecting Rod and Crankshaft End Play Inspection
1. Remove the oil pump (see page 8-16).
2. Remove the baffle plates (see step 8 on page 7-13).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and the
crankshaft.
4. If the connecting rod end play is beyond the service limit, install a new connecting rod, and recheck. If it
is still beyond the service limit; replace the
crankshaft (see page 7-13). 5. Push the crankshaft firmly away from the dial
indicator, and zero the dial against the end of the
crankshaft. Then pull the crankshaft firmly back
toward the indicator, the dial reading should not
exceed the service limit.
6. If the end play is beyond the service limit, replace the thrust washers and recheck. If it is still beyond
the service limit, replace the crankshaft (see page
7-13).
