How to Troubleshoot the Gauges and Indicators
Before troubleshooting the gauge system, refer to multiplex integrated control system B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
The gauge control module has a self-diagnostic function which consists of the following checks:
- The beeper drive circuit check.
- The indicator drive circuit check.
- The switch input test.
- The LCD segments check.
- The gauges drive circuit check (Tachometer, Fuel gauge, Speedometer, Turbo meter
- The communication line check (of the body-controller area network (B-CAN) communication line and the fast-controller area network (F-CAN) communication line between the gauges).
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)
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.
2. Turn the lighting switch ON.
3. Turn the ignition switch to ON (II).
4. Within 5 sec., turn the lighting switch OFF, then ON and OFF again.
5. Within 5 sec., release the SEL/RESET switch, 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 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 OFF, the self-diagnostic mode ends.
The Indicator Drive Circuit Check
When entering the self-diagnostic mode, the following indicators blink:
A/T gear position indicator, A/T temperature indicator, ABS indicator, brake system indicator, charging system indicator, cruise control indicator, cruise main indicator, DRL indicator ('07-08 models without navigation), electric vacuum pump system indicator, fog light indicator, high beam indicator, immobilizer indicator, lights-on indicator, low engine oil pressure indicator, low fuel indicator, low tire pressure indicator, malfunction indicator lamp (MIL), message indicator (with navigation), seat belt indicator, security indicator, SH-AWD indicator, side airbag cutoff indicator smart maintenance indicator ('07-08 models without navigation), SRS indicator, TPMS indicator ('07-08 models without navigation), VSA activation indicator, VSA indicator and washer fluid level indicator (Canada models).
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:
Cruise control master, SET, RESUME, CANCEL switches, multi information switch, SEL/RESET, NEXT, PREVIOUS switches (+), (-) switch, parking brake switch, and VSA OFF switch.
The Beeper Drive Circuit Check
When entering the self-diagnostic mode, the beeper sounds five times.
The LCD Segment Check
With navigation: When entering the self-diagnostic mode, all the segments blink five times.
Without navigation: When entering the self-diagnostic mode, the word "CHECKING NOW" shows on the LCD.
The Gauge Drive Circuit Check
When entering the self-diagnostic mode, the speedometer, the tachometer, the fuel gauge and the turbo meter needle sweeps 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 Gauge Drive Circuit Check again.
The check cannot be started again until the gauge needle returns to the minimum position.
If the needle fails to sweep, or the beeper does not sound, replace the gauge control module.
The Communication Line Check
'07-08 models without navigation
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 a number(s).
Error Code List
Example Indication
- If the word "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 PCM and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
- If the word "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. Troubleshooting - B-CAN System Diagnosis Test Mode A
- If the word "Error 3" 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 PCM and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
'07-08 models with navigation and '09 model
While in the self-diagnostic mode, the Communication Line Check starts after the LCD Segment Check.
If the communication line is OK, the word "OK" will be indicated on multi-information display (MID). If there is a communication line error, the word "NG" will be indicated on the MID.
Indication pattern
There is 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 PCM and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
There is malfunction in the communication line between the B-CAN and the gauge control module. The B-CAN line is OK at this time. Go to B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
There is malfunction in the communication line between the gauge control module, the F-CAN, and the B-CAN. Check for DTCs in the PCM and troubleshoot any DTCs found. If no DTCs are found, go to B-CAN System Diagnosis Test Mode A. Troubleshooting - B-CAN System Diagnosis Test Mode A
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.
