Charging Circuit Troubleshooting (cont'd)
6. Start the engine. Hold the engine at 3,000 rpm with
no load (in Neutral) until the radiator fan comes on,
then let it idle.
7. Raise the engine speed to 2,000 rpm, and hold it
there.
8. Turn the headlights (high beam) on, and measure
voltage at the under-hood fuse/relay box terminal.
ls the voltage between 13.9 and 15.1 v?
YES-Go to step 9.
NO Repair or replace the alternator components
(see page 4-30).1
9. Read the amperage at '13.5 V.
NOTE: Adjust the voltage by turning the blower
motor, rear window defogger, brake lights. etc. ON.
ls the amperage 604 ot morc?
YES-Alternator/regulator operation is OK. I
NO Repair or replace the alternator components(see page 4-30).1

Alternator Control System Test
NOTE: After troubleshooting, perform the engine
control module (ECM) idle learn procedure (see page
11-139).
1 . Check for proper operation of the electrical load
detector (ELD) by checking the malfunction
indicator lamp (MlL) (see page 1 l-3). lf a DTC is
present, diagnose and repair the cause before
continuing with this test.
2. Disconnect the engine wire harness 6P connector
from the starter sub harness 6P connector.
3. Start the engine, and turn the headlights (high
beam) ON,
4. Measure voltage between the engine wire harness
6P connector terminal No. 2 and the positive
terminal of lhe battery.

ENGINE WIRE HARNESS 6P CONNECTOR
Wire side of female terminals
ls there 1 V or less?
YES Go to step 8.
NO-Go to step 5.
Turn the headlights and ignition switch OFF.
Disconnect ECM connector B (24P).

WEC Rocker Arms Test
Special Tools Required. Air pressure regulator 07AAJ-PNAA100. VTEC air adaoter 07ZAJ-PNAA100. WEC air stoDoer 07ZAJ-PNAA200. Air joint adapter 07ZAJ-PNAA300
1. Remove the cylinder head cover (see page 6-22).
2. Set the No. 1 piston at top dead center (TDC) (see
step 1 on page 6-12).
3. Verify that the intake primary rocker arm (A) moves
independently of the intake secondary rocker arm
(B).
. lf the intake primary rockerarm does not move,
remove the primary and secondary rocker arms
as an assembly and check that the pistons in the
secondary and primary rocker arms move
smoothly. lf any rocker arm needs replacing,
replace the primary and secondary rocker arms
as an assemblv, and test.. lfthe intake primary rocker arm moves freely, go
to step 4.
6.
Repeat step 3 on the remaining intake primary
rocker arms with each piston at TDC. When all the
primary rocker arms pass the test, go to step 5.
Check that the air pressure on the shop air
compressor gauge indicates over 400 kPa
(4 kgflcm', 57 psi).
Inspect the valve clearance (see page 6-9).
Remove the sealing bolt (A)from the relief hole,
and install the VTEC air stopper (B).7.
OTAAJ.PNAAlOODOTZAJ-PNAA3OO
Remove the No. 2 and No. 3 camshaft holder bolts,
and installthe VTEC air adapters (C) finger-tight.
Connect the air joint adapter (D), and air pressure
regulator with a 0-100 psi gauge (E).

Rocker Arms and Shafts Inspection
Remove the rocker arm assembly (see page 6-26).
Measure the diameter of the shaft at the first rocker
location.
3. Zero the gauge (A) to the shaft diameter.
6-28
\
4. Measure the inside diameter ofthe rocker arm, and
check it for an out-of-round condition.
Rocker Arm-to-Shaflt Clearance:
Standard lNew):
lntake: 0.025 0.052 mm(0.0010 0.0020 in.)
Exhaust: 0.018 0.056 mm
(0.0007 0.0022 in.)
Service Limit: 0.08 mm (0.003 in.)
5. Repeat for all rockerarms and both shafts. lfthe
clearance is over the Ilmit. replace the rocker shaft
and all overtolerance rocker arms. lf any VTEC
rocker arm needs replacement, replace the rocker
arms (primary and secondary) as a set.
6. Inspect the rocker arm pistons {A}. Push each
piston manually.
lf it does not move smoothly, replace the rocker
arm set.
NOTE: Apply oil to the pistons when reassembling.
