1. Before troubleshooting the turn signal/hazard warning lights system, troubleshoot the system using B-CAN
System Diagnosis Test Mode A (see page 22-93).
2. Check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box. If the fuse is blown, replace it and go to step 3.
3. Disconnect under-dash fuse/relay box connectors E, F, G, M, P, Q, R, S, and T. NOTE: All connector views are shown from wire side of female terminals.

DVD Handling and CleaningEarliest DVD Version Application for Each
Model
23-95
To avoid damaging or leaving fingerprints on the DVD,
always handle it by the edges and place it in a jewel
case whenever it is outside the navigation unit. Deep
scratches or fingerprints on the back of the DVD can
cause intermittent rebooting or other system errors.
Smudges and fingerprints can be carefully removed
using a mild cleaner and tissues designed to clean
eyeglasses. To clean a DVD, use a clean soft cloth. Very
gently wipe across the DVD from the center to the
outside edge, never in a circular motion.
Do not place stabilizer rings or labels on the DVD. Each navigation system DVD contains a map/POI (point
of interest) database and the navigation system
software for each model that it supports. Inserting an
older DVD can cause problems since it lacks the
software to provide the specific features needed for that
model. Unfortunately, the navigation software does not
detect or warn you that the version is outdated, and it
may even appear to operate.
NOTE: Replacing a DVD just because the version
number is higher is not always warranted. A higher
software version does not necessarily mean it contains
newer software for your model. The DVD contains
software for all models that use the same color DVD,
and a revised number may or may not have software
fixes or upgrades for the model in question.
Typical warning symptoms that an outdated DVD is
being used include:
 The Acura model navigation screen displayd a Honda logo while booting up.
 A newly introduced model future or accessory may not display properly, and Extension displays instead.
NOTE: Extension may be displayed when using
Music Link, but should never be displayed when XM
is selected.
 The current street (the street being driven on) does not appear properly at the bottom of the map screen
display when the vehicle is driven on a main road.
NOTE: If necessary, compare the operation to the
navigation system of the same model and year
vehicle that has a current DVD.
