Self-diagnostic Function

Before checking the gauge system, refer to the B-CAN System Diagnosis Test Mode A.

The gauge control module has the self-diagnostic functions shown, and also has the customizable reset function.

NOTE: Indicators are also controlled via the communication line.

Entering the self-diagnostic function with the HDS

Using the HDS, select Body Electrical, Gauges, then Function Test, and do the self-diagnostic function.

Entering the self-diagnostic function (manual method)

NOTE: This procedure takes precise timimg. It may take several tries to enter the self-diagnosis mode.

Before doing the self-diagnostic function, check the No. 10 (7.5 A) fuse in the under-dash fuse/relay box and the No. 23 (10 A) fuse in the under-hood fuse/relay box.

1. Push and hold the SEL/RESET switch button.

2. Turn the headlights ON.

3. Turn the ignition switch ON (II).

4. Within 5 sec., turn the headlights OFF, then ON and OFF again.

5. Within 5 sec., release the SEL/RESET switch button, and then push and release the button three times repeatedly.

NOTE:

Honda CR-V. Gauges

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

Honda CR-V. Gauges

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

Release Locked odometer mileage to the original gauge control module.

If, after you attempt to transfer mileage, the odometer display has dashes (---), is garbled, or shows an incorrect value, the original gauge control module needs to be unlocked and restored to its original state: 1. Confirm that you have the latest HDS version of software.

2. Make sure that the HDS shows the correct VIN for the vehicle you are working on.

3. With the ignition switch OFF, reconnect the original gauge control module.

4. Completely re-boot the HDS.

5. Clear any stored DTCs.

6. Navigate to Body Electric/Gauges/Adjustment! Instrument Panel Replacement.

7. Select "3. Releasing Locked ODO Value."

8. Follow the prompts and the Odometer mileage will be restored.

9. Start over and make sure the screen prompts are followed.

Gauge Control Module Replacement

1. Remove the instrument panel.

2. Remove the three screws from the gauge control module (A).

3. Disconnect the 36P connector (B) from the gauge control module.

4. Install the gauge in the reverse order of removal.

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).

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.

Honda CR-V. Gauges

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.

Honda CR-V. Gauges

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