Frame HONDA CR-V 1997 RD1-RD3 / 1.G Workshop Manual

Towing
lf the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehjcle with just a rope or chain. lt is very dangerous.
Emergency Towing
There are three popular methods of towing a vehicle.
Flat-bed Equipment - The operator loads the vehicle on
the back of a truck. This is the best way of transporting the
vehicle.
Wheel Lift Equipment - The tow truck uses tlvo pivoting
arms that go under the tires lfront or rear) and lifts them
off the ground. The other two tires remain on the
ground. The vehicle's suspension and body can be
seriously damaged if this method of towing is attempted.
Sling-type Equipment - The tow truck uses metal cables
with hooks on the ends. These hooks go around parts of
the frame or suspension and the cables lift that end of
the vehicle off the ground. The vehicle's suspension and
body can be seriously damaged if thjs method of towing
is attempted. This methed of towing the CR-V is
unaccePtable.
The onlv recommended way of towing the CR-V is on a
flat-bed truck. Two wheel drive CR-V's may also be
towed with all four wheels on the ground.
Towing the four-wheel dlive CR-v with only two
wheels on the ground will damage parts of the 4wD
system. It this vehicle is damaged, it should be towed
on a flat-bed truck ol trailel.
It the 2 wheel drive CR-v is towed wiih all tour wheels
on the ground, do the following:
Manual Transmission
. Release the parking brake.
. Shift the transmission in Neutral
Automatic Transmission
. Release the parking brake.
. Sta rt the engine.
. Shift to lD.l position. then E position.
. Turn off the engine.
lmproper towing preparation will damage the
transmission. Follow the above procedure exactly. lf
you cannot shift the transmission or start the engine,
the vehicle must be transported on a flat-bed truck.
lf the vchicle is towed with four wheels on the ground,
il is best to tow the vehicle no larther than 50 miles (80
km), and keep the speed below 35 mph {55 km/h).
Trying to lift or tow the vehicle by ihe bumpers will
cause serious damage. The bumpers ale not dosigned
to support the vehicle's weight.

Troubleshooting Procedures
How To Begin Troubleshooting
When the Malfunction indicator Lamp (MlLl has been reported on, or there is a driveability problem, use the appropri-ate procedure below to diagnose and repair the problem.
A. When the MIL has come on:
1. Connect the Honda PGM Tester or an OBD Il scan tool to the 16P Data Link Connector (DLC) located behind theright side of the center console.
Turn the ignition switch ON (ll).
Check the DTC and note it. Also check and note
the freeze frame data.
Refer to the Diagnostic Trouble Code Chart and
begin troubleshooting.
NOTE:
. SeetheOBDll scan tool or Honda PGM Tester user's manuals for specific operating instructions.. The scan tool or tester can read the Diagnostic Trouble Codes (DTC), freeze frame data, current data, and otherEngine Control Module (ECM}/Powertrain Control Module (PCM) data.. Freeze frame data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction wasdetected. lt can be useful information when troubleshootino.
B. When the MIL has not come on, but there is a driveability problem, refer to the Symptom Chart on page 11-64.
C. DTCs will be indicated by the blinking of the Malfunction Indicator Lamp {MlL) with the SCS service connector con-nected.
Connect the SCS service connector to Service Check Connector as shown. {The 2P Service Check Connecror rslocated behind the right side of the center console.) Turn the ignition switch ON 0l).

Fuel Pump
Testing
lf you suspect a problem with the fuel pump, check that
the fuel pump actually runs; when it is oN (ll), you will
hear some noise if you hold your ear to the fuel fill port
with the fuel fill cap removed. The fuel pump should run
for two seconds when ignition switch is first turned ON (ll).
lf the fuel pump does not make noise, check it as follows:
1. Fold the left rear seat cushion forward, and remove
the base frame cover (see section 20).

BSet idle rpm in gear to specified idle speed. lf still no good, adjust motor mounts as outlined in enginesection of this manual.
clf the large clutch piston O-ring is broken, inspect the piston groove for rough machining.
Dlf the clutch pack is seized or is excessively worn. inspect the other clutches fot wear, and check the orificecontrol valves, CPC valve, and linear solenoid for free movement.
lf the linear solenoid is stuck, inspect the clutches for wear.
lf the 1-2 shift valve is stuck closed. the transmission will not upshift. lf stuck open, the transmission hasno lst gear.
Hlf the 2nd orifice control valve is stuck, inspect the 2nd and 3rd clutch Dacks for wear.
lf the 3-4 orifice control valve is stuck, inspect the 3rd and 4th clutch packs for wear.
Jlf the clutch pressure control valve is stuck closed. the transmission will not shift out of lst gear.
Klmproper alignment of main valve body and torque converter housing may cause ATF pump seizure. Thesymptoms are mostly an rpm-related ticking noise or a high-pitched squeak.
Llf the ATF strainer is clogged with particles of steel or aluminum, inspect the ATF pump and differentialpinion shaft. lf both are OK and no cause for the contamination is found, replace the torque converter.
Mlf the lst clutch feed pipe guide in the end cover is scored by the mainshaft. inspect the ball bearing forexcessive movement in the transmission housing. lf oK, replace the end cover as it is dented. The o-rinounder the guide is probably worn.
N' Replace the mainshaft if the bushing for the 4th feed pipe is loose or damaged, lf the 4th feed pipe is darrFaged or out of round. replace the end cover.' Replace the mainshaft if the bushing for the l st feed pipe is loose or damaged. lf the 1st feed pipe is dam-aged or out of round, replace it.
oA worn or damaged sprag clutch is mostly a result of shifting the transmission in E!. E, or E positionwhile the wheels rotate in reverse. such as rocking the vehicle in snow.
PInspect the frame for collision damage.
lnspect for damage and wear:
l. Reverse selector gear teeth chamfers.
2. Engagement teeth chamfers of countershaft 4th and reverse gear.
3. Shift fork for scuff marks in center.
4. Differential pinion shaft for wear under pinion gears.
5. Bottom of 3rd clutch for swirl marks.
Replace items 1, 2, 3. and 4 if worn or damaged. lf transmission makes a clicking, grinding, or whirring noise,also replace mainshaft 4th gear, reverse idler gear, and countershaft 4th gear in addition to 1,2, 3, or 4.lf differential pinion shaft is worn, overhaul differential assembly, replace ATF strainer, and thoroughly cjeantransmission, flush torque converter. cooler, and lines,lf bottom of 3rd clutch is swirled and transmission makes gear noise. replace the countershaft and final drivenoear,
Be very careful not to damage the torque converter housing when replacing the main ball bearing. you
may also damage the ATF pump when you torque down the main valve body. This will result in ATF pumpseizure if not detected. Use the Drooer tools.
SInstall the main seal flush with the torque converter housing. lf you push it into the torque converterhousing until it bottoms out, it will block the fluid return passage and result in damage.
