BLUETOOTH CONTROL UNIT INITIALIZATION CHECKS
• Internal control unit failure
• Bluetooth antenna connection open or shorted
• Steering wheel audio control switches (SEND/END) stuck closed
• Vehicle speed pulse count
• Microphone connection test (with playback to operator)
• Bluetooth inquiry check
STARTING THE DIAGNOSTIC MODE
1. Turn ignition switch to ACC or ON.
2. Wait for the Bluetooth system to complete initialization and the Bluetooth ON indicator to stop flashing.
This may take up to 10 seconds.

Radio Wave from GPS Satellite Is Not ReceivedINFOID:0000000003533766
1.CHECK ENVIRONMENT
Check if any metal object that intercepts radio waves or an object that emits radio waves (such as a portable
phone) is located near the GPS antenna. Check if the vehicle is shielded by a building.
OK or NG
OK >> System is not malfunctioning. The GPS antenna may not be able to receive radio waves from the
GPS satellite if it is shielded by metal object or an object emitting radio waves is placed near it.
NG >> GO TO 2.
2.SELF-DIAGNOSIS
Perform “Self-diagnosis mode” of the self-diagnosis function. Refer to AV-101, "
Self-Diagnosis Mode (NAVI)".
OK or NG
OK >> Replace GPS antenna. Refer to AV-145, "Removal and Installation".
NG >> Check the malfunctioning parts.
Driving TestINFOID:0000000003533767
1.DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT
LOCATION CORRECTION”.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the "CONFIRMATION/ADJUSTMENT" mode.
Note: Normally, adjustment is not necessary because this system has automatic distance correction func-
tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.
4. Are symptoms malfunctioning to the AV-137, "
Example of Symptom Judged Not Malfunction" after driving
the vehicle?
YES or NO
YES >> Limit of the location detection capacity of the navigation system.
NO >> GO TO 2.
2.DRIVING TEST 2
• Did any malfunction occur when the proper test in the following test patterns is performed?
• Test pattern
Driving test finds the difference between the symptoms monitored with and without each sensor.
- Test pattern 1: Test method with no GPS location correction
Disconnect GPS antenna connector connected to the NAVI control unit. Accurately adjust the current loca-
tion and the direction, then drive the vehicle.
- Test pattern 2: Test method with no map-matching
Accurately adjust the current location and the direction. Eject the map DVD-ROM from the NAVI control unit
with ignition switch turned to OFF, then drive the vehicle. After driving, insert the map DVD-ROM back in the
unit, display the track of the vehicle on the map screen and compare it with the actual road configuration.
• Sample tests
- matching or by GPS>
Perform test pattern 1.
-
Perform test pattern 1 & 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters (feet).
-
Perform test pattern 1 & 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate
the rate of change (increased/decreased) of the distance by comparing with the actual distance.

PRECAUTIONS
•Do not operate fuel pump when there is no fuel in lines.
•Tighten fuel hose clamps to the specified torque.
•Do not depress accelerator pedal when starting.
•Immediately after starting, do not rev up engine unnecessar-
ily.
•Do not rev up engine just prior to shutdown.
•When installing C.B. ham radio or a mobile phone, be sure to
observe the following as it may adversely affect electronic
control systems depending on installation location.
-Keep the antenna as far as possible from the electronic con-
trol units.
-Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
-Adjust the antenna and feeder line so that the standing-wave
radio can be kept smaller.
-Be sure to ground the radio to vehicle body.
