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,
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. 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).
6. Measure the voltage between EGR valve 6P connector terminals No. 2 and No. 3.
Go to step 11.
Go to step 7.

 Vacuum pump/gauge, 0 30 in.Hg, Snap-on YA4000A
or equivalent, commercially available
Do this procedure if the fuel cap warning message
comes on frequently, or if the message does not go off
after the fuel fill cap is tightened and the vehicle is
driven several days.
1. Check the fuel fill cap (the cap must say TIGHTEN TO CLICK). It should turn 1/4 after it’s tight, then it
clicks.
Go to step 2.
Replace or tighten the cap, then go to step 13.
2. Check the fuel fill cap seal (A) and the fuel fill pipe mating surface (B). Verify that the fuel fill cap tether
cord (C) is not caught under the cap.
Replace the fuel fill cap or the fuel fill pipe,
then go to step 13.
Go to step 3. 3. Reinstall and tighten the fuel fill cap.
4. Clear the DTC with the HDS.
5. Start the engine. Hold the engine speed at
3,000 rpm without load (in neutral) until the
radiator fan comes on, then let it idle for 1 minute.
6. Test drive at 72 km/h (45 mph) for 1 minute or more.
Go to step 7.
Intermittent failure, the system is OK at this
time.
7. Turn the ignition switch to LOCK (0).
8. Disconnect the vacuum hose (A) from the EVAP canister purge valve (B) in the engine compartment,
and connect a T-fitting (C) between the vacuum
gauge and the vacuum pump/gauge 0 30 in.Hg,
and the EVAP canister purge valve as shown.
