3. Make sure the HDS communicates with the ECM/ PCM and other vehicle systems. If it doesn’t, go to
the DLC circuit troubleshooting (see page 11-204). If
you are returning from DLC circuit troubleshooting,
skip steps 4 through 9, 20 through 25, and 28
through 30, and do these procedures after
replacing the ECM/PCM;
 Replace the engine oil (see page 8-10) and the engine oil filter (see page 8-11).

NOTE: If the TP POSITION CHECK indicates FAILED,
continue with this procedure.
7. Select the REPLACE ECM/PCM MENU, then select READ DATA, and follow the screen prompts.
NOTE: Doing this step copies (READS) the engine oil life data from the original ECM/PCM so you can later
download (WRITES) it into the new ECM/PCM.
 If READ DATA indicates FAILED, continue with this procedure.
8. A/T model: Select the A/T system with the HDS.
9. A/T model: Select the REPLACE TCM/PCM MENU, then select READ DATA and follow the screen
prompts.
NOTE: Doing this step copies (READS) the ATF life data from the original PCM so you can later download
(WRITES) it into the new PCM.
 If READ DATA indicates FAILED, continue with this procedure. 10. Turn the ignition switch to LOCK (0).
11. Jump the SCS line with the HDS.
12. Do the battery removal procedure (see page 22-69).
13. Remove the cover (A).
14. Remove the bolts (D), then remove the ECM/PCM
(E).
15. Disconnect ECM/PCM connectors A, B, and C. NOTE: ECM/PCM connectors A, B, and C have
symbols (A= , B= , C= ) embossed on them for
identification.

 Fuel pressure gauge attachment set 07AAJ-S6MA150 1. Relieve the fuel pressure (see page 11-322).
2. Disconnect the quick-connect fitting. Attach the fuel pressure gauge set and the fuel pressure gauge.
3. Start the engine, and let it idle.  If the engine starts, go to step 5.
 If the engine does not start, go to step 4.
4. Check to see if the fuel pump is running: Listen to the fuel filler port with the fuel fill cap removed.
The fuel pump should run for 2 seconds when the
ignition switch is first turned on.
 If the pump runs, go to step 5.
 If the pump does not run, do the fuel pump circuit troubleshooting (see page 11- 318).
5. Read the fuel pressure gauge. The pressure should be 330 380 kPa (3.4 3.9 kgf/cm , 48 55 psi).
 If the pressure is OK, the test is complete.
 If the pressure is out of specification, replace the fuel pressure regulator (see page 11-337) and the
fuel filter (see page 11-337), then recheck the fuel
pressure. 1. Remove the fuel tank unit (see page 11-334).
2. Using a hand pump, a hose, and a container
suitable for fuel, draw the fuel from the fuel tank.
3. Reinstall the fuel tank unit (see page 11-335).

The fuel line/quick-connect fittings (A), (B), (C), (D), and
(E) connect the fuel rail (F) to fuel feed hose A (G), fuel
feed hose A to fuel feed hose B (H), fuel feed hose B to
the fuel line (I), the fuel line (J) to the fuel tank unit (K),
the fuel vapor line (L) to the EVAP canister (M) and the
fuel tank vapor recirculation tube (N) to the fuel fill pipe
(O). When removing or installing the fuel feed hose, the
fuel tank unit, or the fuel tank, you need to disconnect
or connect the quick-connect fittings.
Pay attention to the following:  The fuel feed hoses, the fuel line, and the quick- connect fittings are not heat-resistant; be careful not
to damage them during welding or other heat-
generating procedures.
 The fuel feed hoses, the fuel line, and the quick- connect fittings are not acid-proof; do not touch them
with a shop towel that was used for wiping battery
electrolyte. Replace them if they come in contact with
electrolyte or something similar.
 When connecting or disconnecting the fuel feed hoses, the fuel line, and the quick-connect fittings, be
careful not to bend or twist them excessively. Replace
them if they are damaged.
A disconnected quick-connect fitting can be
reconnected, but the retainer on the mating line cannot
be reused once it has been removed from the line.
Replace the retainer when: replacing the fuel rail.
 replacing the fuel line.
 replacing the fuel pump.
 replacing the fuel filter.

NOTE: Before you work on the fuel lines and fittings,
read the Fuel Line/Quick-Connect Fitting Precautions
(see page 11-328). 1. Check the contact area (A) of the line (B) for dirt or damage, and clean it if needed.
2. Insert a new retainer (A) into the connector (B) if the retainer is damaged, or after:
 replacing the fuel rail.
 replacing the fuel feed line.
 replacing the fuel pump.
 replacing the fuel filter.
 replacing the fuel gauge sending unit.
 replacing the EVAP purge pipe.
 replacing the EVAP canister.
 replacing the fuel tank.
 replacing the fuel fill pipe.
 removing the retainer from the line.
 Use the same manufacturer’s retainer and the same size when replacing the retainer (see page
11-328). 3. Before connecting a new fuel tube/quick-connect
fitting assembly (A), remove the old retainer (B)
from the mating line.

Hydraulic Flow

As the engine turns, the ATF pump starts to operate. Automatic transmission fluid (ATF) is drawn through the ATF
strainer (filter) and discharged into the hydraulic circuit. Then, ATF flowing from the ATF pump becomes line pressure
that is regulated by the regulator valve. Torque converter pressure from the regulator valve enters the torque
converter through the lock-up shift valve, and it is discharged from the torque converter. The torque converter check
valve prevents torque converter pressure from rising.
The PCM switches shift solenoid valves ON and OFF. The shift solenoid valve intercepts line pressure from the ATF
pump via the manual valve when the shift solenoid valve is OFF. When the shift solenoid valve is turned ON by the
PCM, line pressure changes to shift solenoid valve pressure at the shift solenoid valve, then the shift solenoid valve
pressure flows to the shift valve. Applying shift solenoid pressure to the shift valves moves the position of the shift
valve, and switches the port of the hydraulic circuit. The PCM also controls A/T clutch pressure control solenoid valves
A, B, and C. The A/T clutch pressure control solenoid valves regulate hydraulic pressure, and applies pressure to the
clutches to engage smoothly. The clutches receive optimum clutch pressure which is regulated by the A/T clutch
pressure control solenoid valves for comfortable driving and shifting under all conditions.
