1-12General Information
Towing
A
B D
C
If the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehicle with a rope or chain. It is very dangerous.
There are three popular methods of towing a vehicle.
The operator loads the vehicle
on the back of a truck.
To accommodate flat-bed equipment, the vehicle is
equipped with front towing hooks (A), front tie down
hook slots (B), rear towing hook (C), and rear tie down
hook slots (D).
The rear towing hook can be used with a winch to pull
the vehicle onto the truck, and the tie down hook slots
can be used to secure the vehicle to the truck.

Ignition Timing

Ignition Timing Inspection

1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
4. Check for DTCs (see page 11-3). If a DTC is present, diagnose and repair the cause before continuing
with this test.
5. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or
neutral (M/T model)) until the radiator fan comes
on, then let it idle.
6. Check the idle speed (see page 11-309).
7. Jump the SCS line with the HDS.
8. Connect the timing light to the service loop (white tape). 9. Aim the light toward the pointer (A) on the cam
chain case. Check the ignition timing under a no
load condition (headlights, blower fan, rear window
defogger, and air conditioner are turned off).
10. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK,
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), then recheck. If the
system work properly, and the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228).
11. Disconnect the HDS and the timing light.

64. Check that the engine/transmission is completely
free of vacuum hoses, fuel and coolant hoses, and
electrical wiring.
65. Slowly lower the engine/transmission about 150 mm (6 in.). Check once again that all hoses and
electrical wiring are disconnected and free from the
engine/transmission, then lower it all the way.
66. Disconnect the chain hoist from the engine/ transmission.
67. Raise the vehicle on the lift, then remove the engine/transmission from under the vehicle.

2. Raise the vehicle on the lift, and position theengine/transmission under the vehicle. Lower the
vehicle, and install the universal lifting eyelet
(07AAK-SNAA120). Attach a chain hoist to the
universal eyelet and the transmission hook, then lift
the engine into position in the vehicle.
NOTE: Reinstall the mounting bolts/support nuts in
the sequence given in the following steps. Failure
to follow this sequence may cause excessive noise
and vibration, and reduce engine mount life.
3. Attach the engine hanger adapter (VSB02C000015) to the threaded hole in the cylinder head. 4. Install the front leg assembly (A), the hook (B), and
the wing nut (C) to an A and Reds engine support
hanger (AAR-T1256) onto the 2006 civic engine
hanger (VSB02C000025). Carefully position the
engine hanger on the vehicle, and attach the hook
to the forward hole in the engine hanger adapter
(D). Tighten the wing nut by hand to lift and support
the engine/transmission.
NOTE: Be careful when working around the
windshield.
5. Loosen the upper torque rod mounting bolt (A). (cont’d)
