lgnition Timing Inspection
1.
4.
5.
Connect the Honda PGM Tester to the data link
connector (DTC), and check for DTC'S. lf a DTC is
present, diagnose and repair the cause before
inspecting the ignition timing.
Startthe engine. Hold the engine at 3,000 rpm with
no load (in Neutral) until the radiator fan comes on,
then let it idle.
Check the idle speed (see page 11-138).
Follow the tester's prompts in the "SCS" menu
{see the tester operator's manual),
Connect the timing light to the service loop.
o
6. Point the light toward the pointer (A) on the cam
chain case. Check the ignition timing under no load
conditions: headlights, blower fan. rear window
defogger, and air conditioner are not operaling. lf
the ignition timing differs from the specification,
and there are no engine control module {ECM)DTcs,
replace the ECM (see page 11-4)

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.

DTC P0505: ldle Control System Malfunction
NOTE: lf DTC P1519 is stored atthe same time as DTC
P0505, troubleshoot DTC P1519 first, then recheck for
DTC P0505.
1. 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,
2. Checkthe engine speed at idle with no,load
conditions: headlights, blower fan, rear defogger,
radiator fan, and air conditioner off.
Is the engine running at 750t50 rpm?
YES - Intermittent failure, system is OK at this
trme.I
NO lf the idle speed is less than 700 rpm, go to
step 3; if it's 800 rpm or higher, go to step 4.
3. Disconnect the idle air control {lAC) valve3P
connector.
Does the engine speed increase or fluctuate?
YES- Check the idle speed {see page 1 1-138). lf the
idle will not adjust properly, clean the passage in
the throttle body, and then adjust the idle. I
NO- Replace the IAC valve.I
4. Turn the ignition switch OFF.
5. Remove the intake air duct from the throttle body.
6. Start the engine, and let it idle.

7. Put your fingers on the lower pon (A) inthethrottle
oooy.
Does the engine stall?
YES Checkthe idle speed (see page 11-138). lfit's
out of specification, replace the IAC valve.l
NO With the throttle valve completely closed,
check for vacuum leaks, and repair as necessary.l

Rear Window Replacement
NOTE:. Put on gloves to protect your hands.. Wear eye protection while cutting the glass adhesive
with piano wire.. Use seat covers to avoid damaging any surfaces.. Do not damage the rear window defogger grid lines
and terminals.
1.Remove these items:
. Hatch lower trim panel (see page 20-53). Hatch spoiler (see page 20-99)
Remove these items:
. High mount brake light {see page 22-821. Rear window wiper motor {see page 22-1461
Disconnect the rear window defogger connectors
(A).
4.lf the old rear window is to be reinstalled, make
alignment marks across the glass and body with a
grease pencrl,
Apply protective tape along the inside and outside
edges of the hatch. Using an awl, make a hole
through the adhesive from inside the vehicle at the
corner portion of the rearwindow. Push the piano
wire through the hole, and wrap each end around a
piece of wood,
6. With a helper on the outside, pull the piano wire (A)
back and Jorth in a sawing motion. Hold the piano
wire as close to the rear window (B) as possible to
prevent damage to the hatch, and carefully cut
through the adhesive {C} around the entire rear
Cutting positions:
7. Carefully remove the rear window.
