10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, and
then do steps 4 thru 10 on the known-good vehicle.
12. Compare the number of stations received in steps 6 and 9 in the client’s vehicle with the number of
stations received in the known-good vehicle.
 If the number of stations received is the same, or within 10 %, the audio unit’s tuner performance
is OK. The problem may be atmospheric
conditions, multi path interference, or other
obstructions to the radio signal.
 If the customer’s vehicle receives fewer stations by at least 10 %, go to step 2 of poor AM or FM
radio reception of interference, with navigation
(see page 23-196), wit hout navigation (see page
23-199). 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.).
 Eject all the discs before removing the audio unit to prevent damaging the CD/DVD player’s load
mechanism.
 If you are replacing the audio unit, write down the audio presets (if possible), and enter them into the
new audio unit.

How to Check for DTCs with the HDS
23-360HandsFreeLink System
General Troubleshooting Information
A
NOTE: Check the vehicle battery condition first.
1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A) located under the driver’s side of the dashboard.
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the HandsFreeLink control unit. If it doesn’t, troubleshoot the DLC circuit (see page 11-204).
5. Select HandsFreeLink in the BODY ELECTRICAL menu.
6. Select DTCs in the HandsFreeLink menu.
7. Check for DTCs. If any DTCs are indicated, write down the DTCs, then go to the indicated DTC troubleshooting. If no DTCs are indicated, refer to symptom troubleshooting.
NOTE: After troubleshooting, clear the DTCs with the HDS.
 For specific operations, refer to the user’s manual that came with the HDS.

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).
