MAINTENANCE MINDER INDICATOR
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.

Maintenance Main Items
If the message ‘‘SERVICE’’ does not appear more than 12 months after the display is reset, change the engine oil every
year.
NOTE:


 Replace the brake fluid every 3 years independent of the maintenance messages in the information display.

Check front and rear brakes (see page 19-3). Check pad and disc for wear (thickness), damage, and cracks.
Check calipers for damage, leaks, and tightness of mounting bolts.
Check parking brake adjustment (see page 19-7). Check the number of clicks (8 to 10) when the parking brake lever is pulled with 196 N (20 kgf,
44 lbf) of force.
Inspect tie-rod ends, steering gearbox, and gearbox boots (see page 17-5). Check steering linkage.
Check boots for damage and leaking grease.
Check fluid lines for damage and leaks.
Inspect suspension components (see page 18-3). Check bolts for tightness.
Check condition of ball joint boots for deterioration and damage.
Inspect driveshaft boots (see page 16-4). Check boots for cracks and boot bands for tightness.
Inspect brake hoses and lines including VSA lines (see page 19-37). Check the master cylinder and VSA modulator-control unit for damage or leakage.
Inspect all fluid levels and condition of fluids. Engine coolant (see page 10-7)
Automatic transmission fluid (ATF-Z1) (see page 14-231)
Manual transmission fluid (MTF)
5M/T (see page 13-5), 6M/T (see page 13-82)
Clutch fluid (see page 12-7)
Brake fluid (see page 19-9)
Windshield washer fluid (see page 22-234)
Inspect exhaust system: K20Z2 (see page 9-13), K20Z3 (see page 9-14)
Check catalytic converter heat shields, exhaust pipes, and muffler for damage, leaks, and tightness.
Inspect fuel lines (see page 11-326) and connections (see page 11-328). Check for loose connections, cra cks, and deterioration; retighten loose connections and replace
damaged parts.
NOTE: According to state and federal regulations, failure to do the maintenance items marked with an asterisk ( ) will
not void the client’s emissions warranties. However, Acura recommends that all maintenance services be done at the
recommended interval, to ensure long-term reliability.

 Before doing this procedure, check that the variable valve timing control (VTC) actuator is locked by
turning the VTC actuator counterclockwise. If not
locked, turn the VTC actuator clockwise until it stops,
then recheck it. If it is still not locked, replace the VTC
actuator.
1. Set the crankshaft to top dead center (TDC). Align the TDC mark (A) on the crankshaft sprocket with
the pointer (B) on the engine block.
2. Set the camshafts to TDC. The punch mark (A) on the VTC actuator and the punch mark (B) on the
exhaust camshaft sprocket should be at the top.
Align the TDC marks (C) on the VTC actuator and
the exhaust camshaft sprocket. 3. To hold the intake camshaft, insert a camshaft lock
pin (07AAB-RWCA120) (A) into the maintenance
hole in camshaft position (CMP) pulse plate A (B)
and through No. 5 rocker shaft holder (C).
4. To hold the exhaust camshaft, insert a camshaft lock pin (A) into the maintenance hole in CMP pulse
