Initial Inspection and Diagnostic Overview
How to Troubleshoot the Gauges and Indicators
'06-09 models
The gauge assembly has a self-diagnostic function that does the following checks. It also has a customizeable reset function.
- Beeper drive circuit check.
- Indicator drive circuit check.
- Switch input test.
- LCD segments check.
- Communication line (Checks the engine coolant temperature signal, engine oil life index, fuel data request signal, CHECK FUEL CAP signal, charging system indicator ON/OFF signal, MIL ON/OFF signal, and cruise control system ON/OFF signal line between the gauge assembly and the ECM.).
Entering the self-diagnostic function
Before doing the self-diagnostic function, check the No. 5 (7.5 A) fuse and the No. 25 (7.5 A) fuse in the under-dash fuse/relay box.
1. Push and hold the TRIP button.
2. Turn the headlights ON.
3. Turn the ignition switch to ON (II).
4. Within 5 seconds, turn the headlights OFF, then ON and OFF again.
5. Within 5 seconds, release the TRIP button, and then push and release the button three more times repeatedly.
NOTE:
- While in the self-diagnostic mode, the dash lights brightness controller operates normally.
- While in the self-diagnostic mode, the TRIP button is used to start the beeper drive circuit test.
- If the vehicle speed exceeds 1.2 mph (2 km/h) or the ignition switch is turned to LOCK (0), the self-diagnostic mode ends.
Indicator Drive Circuit Check
While in the self-diagnostic mode, the following indicators blink:
Brake system indicator, charging system indicator, cruise control indicator, low fuel indicator, low tire pressure indicator*1, maintenance minder indicator, malfunction indicator lamp (MIL), peak power indicator*2, seat belt reminder indicator, and TPMS indicator*1.

Switch Input Check
After the intermittent beeper sounds at the initial stage of self-diagnosis, a beeper sounds continuously while any of the following switch inputs are switched from OFF to ON:
CLOCK button, driver's seat belt buckle switch, illumination (+) button, illumination (-) button, parking brake switch, rear window defogger switch, SEL button, TRIP button, windshield washer switch, and windshield wiper INT switch.
Beeper Drive Circuit Check
When entering the self-diagnostic mode, the beeper sounds five times.
LCD Segment Check
When entering the self-diagnostic mode, all segments blink five times.
Communication Line Check
'06-07 models
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 there is a communication line error, the word "Error" is indicated on the LCD display.
If a communication line error is found, go to symptom troubleshooting. Symptom Troubleshooting
'08-09 models
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 "Err" is indicated on the odometer display followed by a number.
Error Code List
Example Indication
- If "Err 1" is indicated, there is a malfunction in the communication line between the gauge assembly and the fast-controller area network (F-CAN). Check for DTCs in the ECM, and troubleshoot any DTCs found.
If no DTCs are found, go to indicated troubleshooting.
- If "Err 3" is indicated, there is a malfunction in the communication line between the gauge assembly and the ECM. Check for DTCs in the ECM and troubleshoot any DTCs found.
If no DTCs are found, go to the indicated DTC's troubleshooting.
- If "Err 13" is indicated, there is a malfunction in the communication line between the gauge assembly, the ECM, and the fast-controller area network (F-CAN). Check for DTCs in the ECM, and troubleshoot any DTCs found.
If no DTCs are found, go to the indicated DTC's troubleshooting.
If any F-CAN or ECM communication line error is found, check for DTCs with the HDS.
Ending the self-diagnostic function
Turn the ignition switch to LOCK (0).
NOTE: If the vehicle speed exceeds 1.2 mph (2 km/h), the self-diagnostic function ends.
