Initial Inspection and Diagnostic Overview
Gauge Self-Diagnostic Function
NOTE: Before doing the self-diagnostic function, make sure the No. 1 (15 A) and the No. 22 (7.5 A) fuses in the under-dash fuse/relay box are OK.
The gauge control module has a self-diagnostic function which consists of the following checks:
- The indicator drive circuit check.
- The beeper drive circuit check.
- The ambient meter color variation check.
- The switch input test.
- The multi-information display (MID) check.
- The gauges drive circuit check (tachometer, fuel gauge, charge/assist gauge).
- The communication line check of the B-CAN (body-controller area network) communication line and the F-CAN (fast-controller area network) communication line between the gauges.
NOTE:
Indicators are also controlled via the communication lines.
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)
1. Push and hold the SEL/RESET button.
2. Turn the combination light switch () ON.
3. Turn the ignition switch to ON (II).
4. Within 2-5 sec., turn the combination light switch () OFF, then ON and OFF again.
5. Within 5 sec., release the SEL/RESET button, and then push and release the button three times repeatedly.
NOTE:
- While in the self-diagnostic mode, the dashlights brightness controller operates normally.
- While in the self-diagnostic mode, the SEL/RESET switch is used to start the Beeper Drive Circuit Test and the Gauge Drive Circuit Check.
- 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.
The Indicator Drive Circuit Check
When entering the self-diagnostic mode, the following indicators (if equipped) blink:
ABS indicator, VSA OFF indicator, VSA indicator, brake system indicator (Red), A/T gear position indicator, charging system indicator, cruise control indicator, cruise main indicator, EPS indicator, high beam indicator, high temperature indicator, immobilizer indicator, lights-on indicator, low temperature indicator, low oil pressure indicator, low fuel indicator, malfunction indicator lamp (MIL), seat belt reminder indicator, security indicator, door indicator, sequential shift mode shift indicator, message indicator, SRS indicator, side airbag cutoff indicator, IMA system indicator, Eco indicator, auto stop indicator, low tire pressure indicator, brake system indicator (amber).
The Ambient Meter Color Variation Check
When entering the self-diagnostic mode, the color of the ambient meter varies to blue, blue green, and green in that order.
The Beeper Drive Circuit Check
When entering the self-diagnostic mode, the beeper sounds five times.
Switch Input Check
After the beeper drive circuit check, you can check the switch input. The beeper sounds continuously when any of the following switch inputs are switched from OFF to ON:
Cruise control main, SET/DECEL, RES/ACCEL, CANCEL switches, VSA OFF switch, multi-information switch (includes SEL/RESET switch, NEXT switch, and PREVIOUS switch), ECON switch, parking brake switch, km/mph change switch, select/reset knob.
The Multi-Information Display (MID) Check
When entering the self-diagnostic mode, the word "CHECKING NOW" shows on the MID, and blinks five times, then a communication check result is displayed.
The Gauge Drive Circuit Check
When entering the self-diagnostic mode, the tachometer, the fuel gauge, and the charge/assist gauge needles sweep from the minimum position to maximum position, then return to the minimum position.
NOTE:
After the beeper stops sounding and the gauge needles return to the minimum position, pressing the SEL/RESET button starts the Beeper Drive Circuit Check (one beep) and the Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needles return to the minimum position.
If the needles fail 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 Multi-Information Display (MID) Check.
If the communication lines are OK, the word "OK" will be indicated on the multi-information display (MID). If there is a communication line error, the word "ERROR" will be indicated on the MID.
Indication pattern
There is a malfunction in the communication line between the F-CAN and gauge control module. The B-CAN is OK at this time. Check for DTCs in the PCM, and troubleshoot any DTCs found.

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.
