4. Push the PC card eject button (A) to eject the client’sPC card (if installed). Power is not required for this
function.
5. Remove the plastic cover (B) over the navigation DVD slot.
6. With the display open, temporarily reconnect the unit in the dash (to power it up).
7. Push the CD eject button (C), and navigation DVD eject button (D) (the button is behind the plastic
cover and works only when the unit is powered)
and remove the discs (hold the discs by their edges
to avoid fingerprints). To avoid scratches, place the
navigation DVD and the client’s CD in a jewel case
if available.
8. Re-attach the plastic lid that hides the navigation DVD slot.
9. Close the display by first returning the display to the upward position, and then pushing the entire
display straight back into the unit.
10. After installing the new navigation unit, re-insert the navigation DVD, the client’s CD, and the PC card. SRS components are located in this area. Review the
SRS component location (see page 24-11).
Also review the precautions and procedures (see page
24-13) in the SRS section before doing repairs or
service.
NOTE:
Put on gloves to protect your hands.
Take care not to scratch the dashboard and related parts.
Lay a workshop towel under the parts when working on them to protect the face panel from scratches or
other damage.
Do not work in a dusty or dirty place.
Discharge static electricity from your body before and during the work.
Do not touch the circuit board(s) with your bare hands.
Do not work with dirty hands.
Be careful not to fold the flat plate cable.
Do not touch the terminal connector of the flat plate cable with your bare hands. (If you have touched it,
wipe it off thoroughly.)
Before replacing the navigation unit, make sure to remove the client’s navigation DVD, and their audio
CD, or PC card. Remanufactured navigation units do
not come with a navigation DVD. Re-install the client’s
navigation DVD, audio CD, and audio PC card into the
new remanufactured unit. If the navigation display
won’t open, manually remove the navigation DVD,
audio CD, and PC card (see page 23-354).
If you are replacing the navigation unit, write down the audio presets (if possible), then enter them into
the new navigation unit.
1. Make sure you have the 4-digit anti-theft code for the navigation system.
2. Eject the DVD from the original navigation unit. To avoid scratching or damaging the DVD, temporarily
place the DVD in jewel case.
3. Remove the subdisplay visor (see page 20-100).

DTC (Diagnostic Trouble Codes) Reading the DTC
Precautions
24-22SRS
General Troubleshooting Information
A
The self-diagnostic function of the SRS system allows it
to locate the causes of system problems and store this
information in memory. For easier troubleshooting, this
data can be retrieved via a data link circuit.
When you turn the ignition switch to ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the
system is normal, and is not currently detecting any
abnormality.
If there is an abnormality, the system locates and defines the problem, stores this information in
memory, and turns on the SRS indicator. The data
remains in memory even if the ignition switch is
turned off or the battery is disconnected.
The data is stored in memory as a diagnostic trouble code (DTC).
The ‘‘x’’ at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F)
that is displayed on the HDS.
DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS
indicator goes off the next time the ignition switch is
turned to ON (II), and the system is normal, but the
DTC is still stored. With latching DTCs, the SRS
indicator does not turn to LOCK (0) until the
malfunction is repaired and the DTC is cleared.
When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the
HDS ‘‘SRS’’ menu.
NOTE: Only read DTCs from the SRS menu, not from
the SWS menus. SWS (ODS unit) DTCs are subcodes
of SRS unit DTCs. Only troubleshoot the
corresponding SRS DTCs.
After reading and recording the DTC, proceed with the troubleshooting procedure for that code.
Use only a digital multimeter to check the system. Make sure its output is 10 mA (0.01 A) or less when
switched to the smallest value in the ohmmeter range.
A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment
and possible injury. Whenever the ignition switch is in ON (II), or has been
turned to LOCK (0), for less than 3 minutes, be careful
not to bump the SRS unit; the airbags could
accidentally deploy and cause damage or injuries.
Before removing the dashboard wire harness, floor wire harness, disconnect the driver’s airbag
connector, the front passenger’s airbag connector,
both side airbag connectors, both side curtain airbag
connectors and both seat belt tensioner connectors.
Make sure the battery is fully charged. If the battery is dead or low, electrical measurements may not be
correct.
Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect
the SRS unit terminals or the sensor terminals with a
jumper wire. Use only the backprobe set and the
multimeter. Backprobe spring-loaded lock type
connectors correctly.
1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
