Gauges Self-Diagnostic Function

The gauge control module has a self-diagnostic function which consists of the following checks:

	The indicator drive circuit check.
	The switch input check.
	The beeper drive circuit check.
	The LCD check.
	The gauge drive circuit check (engine coolant temperature gauge, fuel gauge, speedometer, and tachometer).
	The communication line check (of the body controller area network (B-CAN) communication line, the fast controller area network (F-CAN) communication line, and the other 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 FUNCTIONAL TESTS and do the self-diagnostic function.

Entering the Self-Diagnostic Function (Manual Method)

Before doing the self-diagnostic function, make sure the No. A21 (10 A) fuse in the under-hood fuse/relay box, and No. B5 (7.5 A) fuse in the under-dash fuse/relay box are OK.

1.	Push and hold the SEL/RESET knob.

2.	Turn the combination light switch to the PARKING position ().

3.	Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

4.	Within 5 sec., turn the combination light switch OFF, then to the PARKING position () and OFF again.

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

NOTE:

	While in the self-diagnostic mode, the dashlights brightness controller operates normally.
	While in the self-diagnostic mode, the SEL/RESET knob 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) or the engine start/stop button is pressed to select the OFF mode, the self-diagnostic mode ends.

The Indicator Drive Circuit Check

When entering the self-diagnostic mode, the following indicators (if equipped) blink:
ABS indicator, ACC indicator, auto high-beam indicator, brake system indicator, CMBS indicator, charging system indicator, cruise control indicator, cruise main indicator, door indicator, ECON indicator, EPS indicator, fog light indicator, high beam indicator, immobilizer indicator, keyless access system indicator, light control indicator, lights-on indicator, LKAS indicator, low fuel indicator, low oil pressure indicator, low tire pressure/TPMS indicator, maintenance minder indicator (Except Mexico models), maintenance required indicator (Mexico model), malfunction indicator lamp (MIL), message indicator, parking and back-up sensor indicator, RDM indicator, safety indicator, seat belt reminder indicator, security indicator, sequential shift mode indicator/gear position indicator (A/T), shift position indicator (A/T), SRS indicator, starter system indicator, VSA indicator, VSA OFF indicator, and washer level indicator.

Switch Input Check

At the initial stage of the self-diagnostic function, the beeper sounds intermittently. The beeper sounds continuously when any of the following switch inputs are switched from OFF to ON:
ECON switch, parking brake switch, SEL/RESET switch, SEL/RESET knob, Cruise control main switch, Cruise control SET/- switch, Cruise control RES/+ switch, Cruise control CANCEL switch, Distance switch, LKAS switch, PREVIOUS switch, NEXT switch, VSA OFF switch, CMBS OFF switch, and TPMS switch.

The Head Up Warning Unit Drive Circuit Check

When entering the self-diagnostic mode, the head up warning indication flashes.

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.

The LCD Segment Check

When entering the self-diagnostic mode, all the segments blink five times.

The Gauge Drive Circuit Check

When entering the self-diagnostic mode, the speedometer, the tachometer, the fuel gauge, and the engine coolant temperature gauge sweep from the minimum position to the maximum position, then return to the minimum position.

NOTE: After the beeper stops sounding and the gauge needles return to the minimum position, pushing the SEL/RESET knob 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.

The Communication Line Check

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

If the communication line is OK, the word ''OK'' will be indicated on the multi-information display. If there is a communication line error, the word ''ERROR'' will be indicated on the multi-information display.

Error Code List (Multi-information display (MID))

Error code	Type of communication line(s) error
F-CAN???ERROR	F-CAN communication
B-CAN???ERROR	B-CAN communication

Error Code List (Segment display)

Error code	Type of communication line(s) error
Error 1	F-CAN communication
Error 2	B-CAN communication
Error 12	F-CAN and B-CAN communication

Indication Example

Multi-information display (MID)

	F-CAN???ERROR: There is a malfunction in the communication line between the gauge control module and F-CAN. Check for DTCs in the PCM, and troubleshoot the indicated DTCs.
	B-CAN???ERROR: There is a malfunction in the communication line between the gauge control module and B-CAN. Check for DTCs in the body electrical system and troubleshoot the indicated DTCs.

Segment display

	If Error 1 is indicated, there is a malfunction in the communication line between the F-CAN and the gauge control module. The B-CAN is OK at this time. Check for DTCs in the F-CAN connected units and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A.
	If Error 2 is indicated, there is a malfunction in the communication line between the B-CAN and the gauge control module. The F-CAN line is OK at this time. Go to B-CAN System Diagnosis Test Mode A.
	If Error 12 is indicated, there is a malfunction in the communication line between the gauge control module, the F-CAN, and the B-CAN. Check the DTCs in the F-CAN connected units and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A.

Ending the Self-Diagnostic Function

Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

NOTE: If the vehicle speed exceeds 1.2 mph (2 km/h), the self-diagnostic function ends.
