Tips and Precautions
Before Troubleshooting
Handling Connectors
22-3
General Troubleshooting Information
A A A
A
1. Check applicable fuses in the appropriate fuse/relay box.
2. Check the battery for damage, state of charge, and clean and tight connections.
 Do not quick-charge a battery unless the battery ground cable has been
disconnected, otherwise you will damage
the alternator diodes.
 Do not attempt to crank the engine with the battery ground cable loosely
connected or you will s everely damage the
wiring.
 Make sure the connectors are clean and have no loose wire terminals.
 Make sure multiple cavity connectors are packed with dielectric grease (except watertight connectors).
 All connectors have push-down release type locks (A).  Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
 Some mounted connectors cannot be disconnected unless you first release the lock and remove the
connector from its mount bracket (A).
 Never try to disconnect connectors by pulling on their wires; pull on the connector halves instead.
 Always reinstall plastic covers.
 Before connecting connectors, make sure the terminals (A) are in place and not bent.

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.

NOTE:
 The MICU turns on the headlights (high beams) in a dimming mode for the Daytime Running Lights under the following conditions:
– With the ignition switch turned to ON (II)
– The headlight switch OFF
– The parking brake is released (parking brake switch OFF)
 The DRL indicator will come on when one of the headlight (high beams) bulbs is blown, or if the high beam wiring has an open circuit with the daytime running lights ON.
 If the vehicle is equipped with an optional remote control engine start system, the daytime running lights will not function when started with the remote start.
1. Before testing the lighting system, troubleshoot the system using B-CAN System Diagnosis Test Mode A (see page 22-93).
2. Check the No. 12 (10 A), No. 13 (10 A), No. 15 (7.5 A), No. 16 (15 A) , (10 A) , No. 17 (15 A) , (10 A) , No. 18 (20 A), No. 19 (15 A), No. 21 (30 A) , (20 A) , and No. 37 (7.5 A) fuses in the under-dash fuse/relay box. If any fuse
is blown, replace it and go to step 3.
1: With HID
2: Without HID
3. Disconnect under-dash fuse/relay box connectors E, F, G, S, and T. NOTE: All connector views are shown from wire side of female terminals.

This screen is for factory use only. It allows adjustment
of the GPS time. This display updates in real time.
 GPS Time is the time as received from the GPS satellites. It is in Greenwich Mean Time (GMT).
 Date, Hour, Minute, and Set should not be used.
This screen allows the navigation system to drive a
route, when the vehicle is stationary. Typical
applications include auto shows, and other events.
This feature allows a visitor to enter a destination, and
see the system drive to the destination. No speed signal
is needed.  To initiate the mode, select ON.
 Changing the speed rate in ms (millisec onds) is
optional, and represents the time between updates of
the VP (vehicle position) movement.
– When you increase the rate, the VP slows down because it is updated (moved) at a slower rate.
– When you decrease the rate, VP is faster because it is updated (moved) more frequently.
– 1500 ms is VP at its slowest in demo mode.
– 150 ms is VP at its fastest in demo mode (Default).
 At key off, the setting automatically returns to the default of Off. This diagnostic screen allows you to independently test
the microphone and the navigation TALK and BACK
buttons. They are used to activate the voice control
system. The microphone is located near the map light
in the ceiling. It is directional, and works best if the
voice is coming from the drivers seat.
 Press the navigation TALK button on the steering wheel, wait unit you hear a beep, and in a normal
voice say ‘‘testing’’. The TALK indicator on the screen
should momentarily turn green, and the text ‘‘Now
Recording...’’ should appear in yellow. If the talk
indicator on the screen does not briefly turn green,
then check the wiring from the navigation TALK
button to the navigation unit.
 If there is no Mic Level movement when you speak, then you should check the wire running from the
microphone to the navigation unit.
 If the mic level bar is full or almost full wit hout you
speaking or other back ground noise, replace the
microphone and recheck.
 PressthenavigationBACKbuttononthesteering wheel. The Cancel indicator on the screen should
momentarily turn green. If it does not briefly turn
green, then check the wiring from the steering wheel
navigation BACK button to the navigation unit.
NOTE: The mic level should reach the 6th bar.
