Symptom Troubleshooting (cont’d)
NOTE:
 Check the vehicle battery condition first.
 Check that the GPS antenna is plugged in.
 This is not the same condition as when driving off- road (or on a fire or logging road). This condition is
caused by a loss of map matching from a bad sensor
input. Check for after market window tinting or other
objects that can block the GPS signal. Always do the
Map matching (see page 23-269) before proceeding
with the troubleshooting.
 Make sure that the correct DVD color and version are installed.
 Inspect the DVD for dirt or damage.
 Check any official Honda service website for more service information about the navigation system.
 Check the GPS signal reception in an open area.
1. Check the GPS icon on the navigation screen.
Do the troubleshooting for GPS icon is white
or not shown (see page 23-341).
Go to step 2. 2. Go into the Self-Diagnosis Mode, and use the Yaw
Rate test (see page 23-314) to check the yaw rate
sensor.
3. Go into the Self-Diagnosis Mode, and use the Car Status test (see page 23-315) to check the vehicle
speed pulse.
The condition may be normal. Check to see if
the condition occurs in the same place in a known-
good vehicle. If it does, the problem could be in the
database.Gotostep4.
If the problem is the yaw rate sensor, replace
the navigation unit (see page 23-355). If the
problem is the vehicle speed pulse, check for an
open in the wire between the navigation unit and
the ECM/PCM (VSP signal). If the wire is OK,
substitute a known-good navigation unit, and retest.
If the problem goes away, replace the original
navigation unit. If the problem is still present,
replace the ECM/PCM.
4. Substitute a known-good navigation unit, and check to see if the problem occurs in the same
place.
The problem is in the database. Report the
problem according to the Navigation System
Manual under Reporting Errors.
Replace the original navigation unit (see page
23-355).
Is the GPS icon white? Ar e t he y aw r at e sensor and v ehi cl e speed pul se

Wiring Precautions
Precautions for Electrical Inspections
24-16SRS
Precautions and Procedures (cont’d)
Some of the SRS wiring can be identified by a special
yellow outer covering, and the SRS connectors can be
identified by their yellow color. Observe the following
instructions:
 Never attempt to modify, splice, or repair SRS wiring. If there is an open or damage to the SRS wiring,
replace the harness.
 Be sure to install the harness wires so they do not get pinched or interfere with other parts.
 Make sure all SRS ground locations are clean, and grounds are securely fastened for optimum metal-to-
metal contact. Poor grounds can cause intermittent
problems that are difficult to diagnose.
 Do not use any silicone based cleaners or lubricants on any SRS connectors or terminals.  When using electrical test equipment, insert the
probe of the tester into the wire side of the connector.
Do not insert the probe of the tester into the terminal
side of the connector, and do not tamper with the
connector.
 Use backprobe adapter 07TAZ-001020A. Do not insert the probe forcibly.
 Use specified service connectors in troubleshooting. Using improper tools could cause a diagnostic error
due to poor metal-to-metal contact.
