Initial Inspection and Diagnostic Overview
Self-diagnostic Function'06-08 models
The gauge assembly has a self-diagnostic function shown, and also has a customizeable reset function.
- The beeper drive circuit check.
- The indicator drive circuit check.
- The switch input test.
- The LCD segments check.
- The communication line check 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 ON (II).
4. Within 5 sec, turn the headlights OFF, then ON and OFF again.
5. Within 5 sec, release the TRIP button, and then push and release the button three 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 OFF, the self-diagnostic mode ends.
The 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.
* 1:'08 model
* 2:'08 CR model
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.
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, the all segments blink five times.
The 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" will be indicated on the LCD display.
If the communication line error is found, go to symptom troubleshooting.
'08 model
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" will be indicated on the odometer display followed by number(s).
- If the word "Err 1" is indicated, there is a malfunction in the communication line between the gauge assembly, 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 the word "Err 3" is indicated, there is a malfunction in the communication line between the gauge assembly, the ECM. Check for DTCs in the ECM and troubleshoot any DTCs found.
If no DTCs are found, go to indicated troubleshooting.
- If the word "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 indicated troubleshooting.
If any F-CAN or ECM communication line error is found, go to DTC check using HDS.
Ending the self-diagnostic function
Turn the ignition switch OFF.
NOTE: If the vehicle speed exceeds 1.2 mph (2 km/h), the self-diagnostic function ends.
