NOTE:

• While in the self-diagnostic mode, the dash lights brightness controller operates normally.
• While in the self-diagnostic mode, the SEL/RESET button is used to start the Beeper Drive Circuit Test and the Gauge Drive Circuit Check.

The Indicator Drive Circuit Check

When entering the self-diagnostic mode, the following indicators blink: ABS indicator, A/T gear position indicator, brake system indicator, charging system indicator, cruise control indicator, cruise indicator, door indicator, DRL indicator, high beam indicator, immobilizer indicator, lights-on indicator, low tire pressure indicator, low fuel indicator, malfunction indicator lamp (MIL), maintenance required indicator, oil pressure indicator, seat belt indicator, security indicator, side airbag cutoff indicator, SRS indicator, tailgate indicator, TPMS indicator, VSA indicator, VSA activation indicator, and washer fluid level indicator (Canada models).

Switch Input Check

At the initial stage of the self-diagnostic function, the beep sounds intermittently, the beeper sounds continuously when any of the following switch inputs are switched from OFF to ON: Cruise control main, SET, RESUME, CANCEL switches, SEL/RESET switch, parking brake switch, and VSA OFF switch.

The illumination volume (+) and (-) switch (dash lights brightness controller) can be tested by turning on the headlights and verifying that the dash lights brightness changes as you turn the switch from full dim to full bright.

The Beeper Drive Circuit Check

When entering the self-diagnostic mode, the beeper sounds five times.

The LCD Segment Check

When entering the self-diagnostic mode, all the segments blink five times. After that, all segments come on.

The Gauge Drive Circuit Check

When entering the self-diagnostic mode, the speedometer and tachometer needles sweep from the minimum position to maximum position, then returns to the minimum position.

NOTE:

After the beeper stops sounding and the gauge needle returns to the minimum position, pushing the SEL/RESET switch starts the Beeper Drive Circuit Check (one beep) and the

If the needle fails to sweep, or the beeper does not sound, replace the gauge control module.

The Communication Line Check

While in the self-diagnostic mode, the Communication Line Check starts after the LCD Segments Check.

If all segments come on, the communication line is OK. If faulty, the word "Error" will be indicated on the odometer display followed by number(s).

Error Code List

Example Indication

Outside Air Temperature Indicator Calibration

Description

The outside temperature sensor is located behind the center of the front bumper. The gauge control module uses measurements from this sensor to display the outside air temperature.

Because of the location of the sensor, it may be affected by heat, reflection from the road, engine and radiator heat or hot exhaust from surrounding traffic.

These conditions can heat soak the outside air temperature sensor and cause inaccurate readings.

Logic has been written into the gauge control module to help prevent abnormal of fluctuating outside air temperature indicator readings.

Outside Air Temperature Indicator Logic

Initial outside air temperature indication after the ignition switch is turned ON (II).

• If the engine coolant temperature is 140ºF (60 ºC) or higher when the ignition switch is turned ON (II), the outside air temperature will be indicated the last reading before the key was turned off regardless of the current temperature measured by the outside air temperature sensor.
• If the engine coolant temperature is 139ºF (59 ºC) or lower when the ignition switch is turned ON (II), the current temperature measured by the outside air temperature sensor will be indicated.

Update to the outside air temperature indicator while driving

If the temperature measured by the outside air temperature sensor is greater than the temperature on the outside air temperature indicator, the outside temperature indicator will increase by 1 ºF (1 ºC) per minute after the vehicle speed is greater than 19 mph (30 km/h) for more than 1 minute and 30 seconds. It will continue to increase until the current outside air temperature is indicated. So, the first change to the outside air temperature indicator is 1 minute and 30 seconds after the vehicle speed is greater than 19 mph (30 km/h). lf the vehicle speed drops below 19 mph (30 km/h), the indicator will not update again until the vehicle speed is increased to 19 mph (30 km/h) or more for more than 1 minute and 30 seconds again.

If the outside air temperature is less than 140 ºF (60 ºC), the temperature increases 1 ºF (1 ºC) every 2 seconds until the current outside air temperature.

If the outside air temperature is less than the indicated temperature, the temperature will decrease 1 ºF (1 ºC) every 2 seconds until the current outside air temperature is indicated regardless of vehicle speed.

Troubleshooting

If the indicator displays "---" for more than 2 seconds after selecting the outside air temperature display mode, check the climate control system or multiplex integrated control system for DTCs (see B-CAN System Diagnosis Test Mode A).

Calibration

The outside air temperature indicator's displayed temperature can be recalibrated +-5ºF or +-3 ºC to meet the customer's expectations.

Calibrate the outside air temperature with the HDS.

Outside Air Temperature Sensor Test

1. Remove the outside air temperature sensor.

2. Dip the sensor in ice water, and measure the resistance. Then pour warm water on the sensor, and check for a change in resistance.

3. Compare the resistance reading between the No.1 and No.2 terminals of the outside air temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.

4. If the resistance is not as specified, replace the outside air temperature sensor.

Outside Air Temperature Sensor Replacement

1. Disconnect the 2P connector (A) from the outside air temperature sensor (B).

2. Lift the tab (C) to release the lock, then remove the outside air temperature sensor from the front bumper.

3. Install the sensor in the reverse order of removal.
