1999 HONDA CR-V Engine ground

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.

Precautions for Real-time 4WD (Four-wheel Drivel
Under normal conditions, the vehicle is in 2WD (front-wheel drive). However, the system will instantly transmit
appropriate driving force to the rear wheels {depending on the driving force of the front wheels and the road conditons)
The Real-time 4WD-Dual Pump System does not have a manual switch to disable the 4WD system. Whenever service
work requires spinning the front or rear wheels with the engine, always lift up and support the vehicle so all lour wheels
are off the ground (see page 1- 19).

Starting System
Starter Test
NOTE: The air temperature must be between 59 and'100'F (15 and 38"C) before testing.
Recommended Procedure:
. Use a staner system tester.
. Connect and operate the equipment in accordance
with the manufacturer's instructions.
. Test and troubleshoot as described.
Alte.nate Procedure:
. Use the following equipment:- Ammeter, 0 - 400 A- Voltmeter, 0 - 20 V (accurate within 0.1 volt)
Tachometer,0 - 1,200 rpm
. Hook up a voltmeter and ammeter as shown.
NOTE: After this test, or any subsequent repair. reset
the ECM/PCM to clear any codes (see section 1 1).
Check the Starter Engagement:
'1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box.
2. Turn the ignition switch to START (lll) with the shift
lever in E or E position (A/T) or with the clutch
pedal depressed {M/T). The starter should crank the
eng ine.
. lf the starter does not crank the engine, go to
step 3.
. lf it cranks the engine erratically or too slowly, go
to "Check for Wear and Damage" on the next
page.

staner cut relay, and the wire connections for loose-
ness and corrosion. Test again.
lf the staner still does not crank the engine, go to
step 4.
Unplug the connector (BLK /VHT wire and solenoid
terminal) from the starter.
Connect a jumper wire from the baftery positive (+)
terminal to the solenoid terminal.
The starter should crank the engine.
. lf the starter still does not crank the engine,
remove it, and diagnose its internal problem.
. lf the starter cranks the engine, go to step 6.
Check the ignition switch (see section 23).
Check the starter cut relay {see section 23}.
Check the IVT gear position switch (A/T) or the clutch
interlock switch (M[).
Check for an open in the wire between the ignition
switch and starter.

Starting System
Starter Test (cont'dl
Check lor Wear and D8mage
The starter should crank the engine smoothly and
steadily. lf the staner engages, but cranks the engine
erratically, remove it, and inspect the starter drive gear
and torque converter ring gear or flywheel ring gear for
oamage.
Check the drive gear overrunning clutch for binding or
slipping when the armature is rotated with the drive
gear held. lf damaged, replace the gears.
Check Cranking Voltage and Current Draw
Cranking voltage should be no less than 8.7 volts on Ay'T
models, and 8.0 volts on M/T moders.
Current draw should be no more than 230 amperes on
A,/T models, and 200 amperes on M/T models.
lf cranking voltage is too low, or current draw too high,
check for:
. dead or low battery.
a open circuit in starter armature commutator seg,
ments.
. starter armature dragging.
. shorted armature winding.
. excessive drag in engine.
Check Cranking rpm
Engine speed during cranking should be above 100 rpm.
lf speed is too low, check for:
a loose baftery or starter terminals.
. excesslvely worn staner brushes
. open circuit in commutator segments.
. dirty or damaged helical splines or drive gear.
a defective drive gear overrunning clutch.
Check Starter Disengagement
With the shift lever in @ or @ position (A,iT) or with the
clutch pedal depressed {M/T). turn the ignition switch to
START (lll). and release to ON (ll).
The starter drive gear should disengage from the torque
converter ring gear or flywheel ring gear when you
release the key.
lf the drive gear hangs up on the torque converter ring
gear or flywheel ring gear, check for
. solenoid plunger and switch malfunction.
. dirty drive gear assembly or damaged overrunning
clutch.
Starter Solenoid Test
1. Check the hold-in coil for continuity between the S
terminal and lhe armature housing (ground). The
coil is OK if there is continuity.
