33. Check the APP SENSOR in the Data List with theHDS. Do not press the accelerator.
Check the APP sensor (see page 11-268).
Reconnect all connectors, then update the
PCM if it does not have the latest software
(see page 11-227), or substitute a known- good PCM
(see page 11-7), then recheck. If the symptom goes
away with a known-good PCM, replace the original
PCM (see page 11-228). SRS components are located in this area. Review the
SRS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repair or service.
1. Turn the ignition switch to ACCESSORY (I). The shift lever must be in P.
2. Disconnect the steering lock assembly connector.
3. Check if the ignition switch can be turned to the LOCK (0) position.
Go to step 4.
Replace the ignition key cylinder/steering lock
assembly (see page 17-14).
4. Turn the ignition switch to LOCK (0).
5. Move the shift lever out of P.
6. Check for continuity between steering lock assembly connector terminal No. 3 and body
ground.
Repair short to body ground in the wire
between the key interlock solenoid and the
MICU.
Go to step 7.
7. Remove the shift lever assembly (see page 14-254).

1. Remove the steering column (see page 17-10).
2. Do these checks:  Check the steering column ball bearing (A) andthe steering joint (B) for play and proper
movement. If any bearing is noisy or has
excessive play, replace the steering column as an
assembly.
 Check the lower slide shaft (C) for smooth movement in and out. If the lower slide shaft is
removed, slip it into the upper shaft by aligning
the paint or stamped marks (D). If it sticks or
binds, replace the steering column as an
assembly.
 Check the sliding capsules (E) for distortion or breakage. If there is distortion or breakage,
replace the steering column as an assembly.
 Check the tilt mechanism and telescopic mechanism for movement and damage.
 Check the absorbing plates (F) for distortion or breakage. If there is distortion or breakage,
replace the steering column as an assembly.
3. Install the steering column (see page 17-12). 1. Remove the steering column (see page 17-10).
2. Center-punch both of the two shear bolts, and drill
the heads of the bolts off with a 5 mm (0.20 in.) drill
bit. Be careful not to damage the switch body when
removing the shear bolts.
3. Remove the shear bolts from the switch body.
4. Install the switch body without the key inserted.
5. Loosely tighten the new shear bolts.
6. Insert the ignition key, and check for proper operation of the steering wheel lock and that the
ignition key turns freely.
7. Tighten the shear bolts (A) until the hex heads (B) twist off.
8. Rewrite the immobilizer control unit-receiver (see page 22-329), and make sure the immobilizer
system works properly.
9. Install the steering column (see page 17-12).

10. If necessary, remove the special screws, then separate the door cylinder (A) and the outer handle
protector (B). If the retainer (C) is damaged, release
the hooks (D), and replace it.
NOTE: If removed, the special screws must be
replaced.
11. While pulling the outer handle (A), remove the handle from the holes in the door panel. Take care
not to scratch the door. 12. Remove the rod fastener (A) from the outer handle
(B), then replace it with a new one.
13. Install the handle in the reverse order of removal, and note these items:
 Make sure the cylinder cable and each rod is connected securely.
 Make sure the door key cylinder/door locks operate properly.
 Make sure the door handle works properly.
 When reinstalling the door panel, make sure the
plastic cover is installed properly and sealed
around its outside perimeter to seal out water.
 Check for water leaks (see step 9 on page 20-29).
Replace.

Testing and Repairs
Five-step Troubleshooting
22-5
 Do not use wires or harnesses with broken insulation.
Replace them or repair them by wrapping the break
with electrical tape.
 Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage is SRS wiring or
terminals, replace the harness.
 After installing parts, make sure that no wires are pinched under them.
 When using electrical test equipment, follow the manufacturer’s instructions and those described in
this manual.
 If possible, insert the probe of the tester from the wire side (except waterproof connector).
 Use back probe adaptor 07TAZ-001020A.
 Refer to the instructions in the Honda Terminal Kit for identification and replacement of connector terminals. 1. Verify The Complaint:
Turn on all the components in the problem circuit
to verify the client complaint. Note the symptoms.
Do not begin disassembly or testing until you have
narrowed down the problem area.
2. Analyze The Schematic: Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by
tracing the current paths from the power feed
through the circuit components to ground. If
several circuits fail at the same time, the fuse or a
ground is a likely cause.
Based on the symptoms and your understanding of
the circuit operation, identify one or more possible
causes of the problem.
3. Isolate The Problem By Testing The Circuit: Make circuit tests to check the diagnosis you made
in step 2. Keep in mind that a logical, simple
procedure is the key to efficient troubleshooting.
Test for the most likely cause of failure first. Try to
make tests at points that are easily accessible.
4. Fix The Problem: Once the specific problem is identified, make the
repair. Be sure to use proper tools and safe
procedures.
5. Make Sure The Circuit Works: Turn on all components in the repaired circuit in all
modes to make sure you’ve fixed the entire
problem. If the problem was a blown fuse, be sure
to test all of the circuits on the fuse. Make sure no
new problems turn up and the original problem
does not recur.
