The overhead console with the compass, temperature and fuel economy readings is not working. The owners manual does not have the fuse number location and all fuses where checked and seem fine. Any suggestions??

The Ambient Air Temperature Sensor is what you want , an it is located in front of the a/c condenser . remove

1. the pin-type retainers and remove the radiator sight shield

1. Disconnect the connector.

Electronic Compass The compass display and module are contained in the overhead console and are replaced as an assembly. For additional information, refer to Section 501-12 . The compass display can be turned off and on by pressing the MODE button in the overhead console. The vehicle heading is displayed as one of N, NE, E, SE, S, SW, W, or NW.
Inspection and Verification
NOTE: Press the MODE button to turn on the display.

1. Verify the customer concern by operating the vehicle along roads of known direction to duplicate the customer concern with the compass.

1. Visually inspect for obvious signs of mechanical or electrical damage.

Visual Inspection Chart Mechanical Electrical

• Compass module

• Central junction box (CJB) fuse 15 (7.5A)
• Circuitry

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

1. If the fault is not visually evident, determine the symptom and GO to Symptom Chart .

Pinpoint Test A: The Compass Is Inaccurate/Inoperative
Normal Operation The compass receives battery voltage from the central junction box (CJB) through circuit 964 (DB/LG). Ground for the compass is supplied through circuit 676 (PK/OG).

Possible Causes
• fuse
• circuit 676 (PK/OG) open
• circuit 964 (DB/LG) open or short to ground
• compass zone setting
• compass calibration
• compass module

PINPOINT TEST A: THE COMPASS IS INACCURATE/INOPERATIVE NOTE: Always set the zone and calibrate the compass before replacing an inaccurate compass.
NOTE: After installing a new compass, always set the zone and calibrate.
Test Step Result / Action to Take A1 CHECK THE OVERHEAD COMPASS DISPLAY

• Key in ON position.
• Check the overhead display.
• Does the overhead compass display remain on after prove out?

Yes
GO to A3 .

No
GO to A2 . A2 CHECK THE COMPASS MODE

• Press and release the SELECT switch on the overhead console.
• Does the overhead compass display turn on?

Yes
If the compass display turns on correctly, GO to A3 . If the compass display turns on, but the heading is inoperative/inaccurate or the display indicates VAR, GO to A4 . If the compass display turns on, but it does not display all directions, or indicates CAL, GO to A5 .

No
GO to A7 . A3 CHECK THE COMPASS DIMMING

• Turn the headlamp switch to the parking lamps ON position.
• Does the compass display dim?

Yes
TURN the headlamp switch to the OFF position. GO to A4 .

No
TURN the headlamp switch to the OFF position. GO to A8 . A4 CHECK THE COMPASS ZONE SETTING

• Set the compass to the correct zone for your location. Refer to Compass Zone Adjustment in this section.
• Does the zone adjustment set correctly?

Yes
GO to A5 .

No
INSTALL a new overhead console. REFER to Section 501-12 . TEST the system for normal operation. A5 CALIBRATE THE COMPASS

• Calibrate the compass. Refer to Compass Calibration in this section.
• Is the compass calibrated correctly?

Yes
GO to A6 .

No
INSTALL a new overhead console. REFER to Section 501-12 . TEST the system for normal operation. A6 CHECK THE COMPASS ACCURACY

• Position the vehicle at each of the 8 directions (N, NE, E, SE, S, SW, W, NW) and verify that the displayed heading is accurate. The vehicle must be stationary for at least 10 seconds at each direction.
• Is the compass display accurate in each direction?

Yes
The compass is OK. REVIEW the operation of the compass with the customer.

No
INSTALL a new overhead console. REFER to Section 501-12 . TEST the system for normal operation. A7 CHECK THE VOLTAGE SUPPLY TO THE OVERHEAD CONSOLE

• Key in OFF position.
• Disconnect: Overhead Console C930.
• Key in ON position.
• Measure the voltage between the overhead console C930-1, circuit 964 (DB/LG), harness side and ground.
• Is the voltage greater than 10 volts?

Yes
TURN the key to the OFF position. GO to A9 .

No
VERIFY the CJB fuse 15 (7.5A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation. A8 CHECK THE DIMMING CIRCUIT

• Key in OFF position.
• Disconnect: Overhead Console C930.
• Turn the headlamp switch to the parking lamps ON position.
• Measure the voltage between the overhead console C930-4, circuit 484 (OG/BK), harness side and ground while rotating the instrument panel dimmer switch.
• Does the voltage vary between 0 and 10 volts?

Yes
GO to A9 .

No
REFER to Section 413-00 for further diagnosis of the instrument cluster and panel illumination. A9 CHECK CIRCUIT 676 (PK/OG) FOR OPEN

• Measure the resistance between the overhead console C930-2, circuit 676 (PK/OG), harness side and ground.
• Is the resistance less than 5 ohms?

Yes
INSTALL a new overhead console. REFER to Section 501-12 . TEST the system for normal operation.

No
REPAIR the circuit. TEST the system for normal operation.

With any electrical problem always check the fuses first.The location of the fuse will be in your owners manual.

This is a very common issue with this, and many other overhead consoles of this era. I offer a repair solution with a lifetime guarantee. Check it out: www,autoclockrepair.com
I have info on how to remove the console etc there as well. Drop me a note if you have any questions, thanks!

The overhead console is quite prone to internal failure. Dim, intermittent, or dead displays are a common symptom of an internal failure. We offer a reasonable repair service with a lifetime guarantee. Check it out: www.autoclockrepair.com

Are your cruise control, dome, and tail lights also out? If so then it is a fuse. If not then the control unit has gone bad internally. You may be able to get it fixed under your warranty.
If it is not covered by your warranty, check out
www.autoclockrepair.com. We offer a very reasonable repair solution.

I believe that the mirrors and entry issues are not related to the overhead console. Compass/temp failure is a very common problem with many of the mid 2000 Ford truck and SUV overhead consoles. The console is very prone to internal failure. If the dome lights work but the compass unit does not then it is a faulty computer unit.

There is a bunch of useful info there. Drop me an email if you have questions, thanks!

The 10 amp IGI #2 fuse controls several other components including the dome light, cruise control, and brake lights. If these are working but the compass is dim, intermittent, or dead then the control module has gone bad. You can get a replacement from toyota but I believe it costs $500+.
