34. Update the ECM/PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
35. Start the engine. Hold the engine speed at 3000 rpm wit hout load (A/T in P or N, M/T in
neutral) until the radiator fan comes on, then let it
idle.
36. Do the EGR TEST in the INSPECTION MENU with the HDS.
37. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the EGR valve and the ECM/PCM. If the
ECM/PCM was updated, substitute a known-good
ECM/PCM (see page 11-7), then go to step 35. If the
ECM/PCM was substituted, go to step 1.
Go to step 38.
38. Monitor the OBD STATUS for DTC P0404 in the DTCs MENU with the HDS.
If the ECM/PCM was updated,
troubleshooting is complete. If the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228). If any other Temporary DTCs or
DTCs were indicated in step 37, go to the indicated
DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the EGR valve
and the ECM/PCM. If the ECM/PCM was updated,

go to step 1. If the screen indicates EXECUTING,
keep idling until a result comes on. If the screen
indicates OUT OF CONDITION, go to step 35. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. Check EGR VLS in the DATA LIST with the HDS.
Go to step 3.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the EGR valve and the ECM/PCM.
3. Turn the ignition switch to LOCK (0).
4. Disconnect EGR valve 6P connector.
5. Turn the ignition switch to ON (II).

NOTE:  Do not reuse the drained fluid. Always use Acura DOT 3 Brake Fluid from an unopened container.
Using a non-Acura brake fluid can cause corrosion
and shorten the life of the system.
 Do not mix different brands of brake fluid; they may not be compatible.
 Make sure the brake fluid is not contaminated with dirt or other foreign matter.
 Do not spill brake fluid on the vehicle; it may damage the paint or plastic. If brake fluid does contact the
paint or plastic, wash it off immediately with water.
 If may be necessary to limit the movement of the release fork with a block of wood to remove all the air
from the system.
 Use fender covers to avoid damaging painted surfaces.
1. Make sure the brake fluid level in the clutch reservoir (A) is at the MAX (upper) l evel line (B).2. Attach the one end of a clear tube to the bleeder
screw (A), and put the other end into a container.
Loosen the bleeder screw to allow air to escape
from the system.
3. Make sure there is an adequate supply of fluid in the reservoir, then slowly push the clutch pedal all
the way down. Before releasing the pedal, have an
assistant temporarily tighten the bleeder screw.
Loosen the bleeder screw, and push the pedal
down again. Repeat this step until no more bubbles
appear at the clear tube.
NOTE: Make sure the fluid level on the reservoir
does not go below MIN.
4. Tighten the bleeder screw securely.
5. Refill the brake fluid in the reservoir to the MAX (upper) l evel line.
