hi its jim, i'm here to help you out, is the check light on and did this problem happen all of a sudden, any previous work, let me jim
This car was in an accident in the right front corner, the check engine light is on.
I plugged in to check the check engine light and it won't communicate with the vehicle.
What are you thinking Jim?
Before doing the self-diagnostic function, make sure 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 are OK.
Push and hold the SEL/RESET button.
Turn the combination light switch () ON.
Turn the ignition switch to ON (II).
Within 5 sec., turn the combination light switch OFF, then () ON and OFF again.
Within 5 sec., release the SEL/RESET button, and then push and release the button three times repeatedly.
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.
When entering the self-diagnostic mode, the following indicators (if equipped) blink:
ABS indicator*1, A/T gear position indicator, brake system indicator, charging system indicator, cruise control indicator, cruise main indicator, door indicator, DRL indicator*2, EPS indicator*3, fog light indicator*4, high beam indicator, immobilizer indicator, lights-on indicator, low fuel indicator, low oil pressure indicator*5, low tire pressure indicator, maintenance required indicator, malfunction indicator lamp (MIL), REV limit indicator, seat belt reminder indicator, security indicator, side airbag cutoff indicator, SRS indicator, TPMS indicator*5, trunk indicator, VSA activation indicator*6, VSA indicator*7, and washer fluid level indicator (Canada models).
*1: Without VSA*2: Canada models and '08-11 USA models*3: Si and '08-11 DX-G (MT) model*4: '09-11 Si models*5: '08-11 USA models*6: Without VSA*7: With VSA
At the initial stage of the self-diagnostic function, the beep sounds intermittently, the beeper sounds continuously when any of the following switch inputs are switched from OFF to ON:
Cruise control master, dashlights brightness controller volume (＋), (－) switch and odometer select/reset switch, SET, RESUME, CANCEL switches, SEL/RESET switch, mph－km/h switch, Parking brake switch, and VSA OFF switch (With VSA).
When entering the self-diagnostic mode, the beeper sounds five times.
4-door: When entering the self-diagnostic mode, all the segments blink five times.
2-door: Self-diagnostic function does not operate the fuel gauge and coolant temperature gauge.
Then a communication line check result is displayed.
When entering the self-diagnostic mode, the tachometer, 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 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 needle returns to the minimum position.
If the needle fails to sweep, or the beeper does not sound, replace the gauge control module (tach).
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 number(s).
Type of communication line(s) error
F-CAN and B-CAN communication
F-CAN and UART communication
B-CAN and UART communication
F-CAN, B-CAN, and UART communication
If the word Error 1 is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the fast-controller area network (F-CAN). Check for DTCs in the ECM/PCM and troubleshoot any DTCs found. If no DTCs are found, go to indicated troubleshooting.
If the word Error 2 is indicated, there is a malfunction in the communication line between the gauge control module (tach) and the body-controller area network (B-CAN). Go to indicated troubleshooting (B1155 to B1160).
4-door: If word Error 3 is indicated, there is a malfunction in the UART communication line between the gauge control module (tach) and the gauge control module (speedo). Go to the gauge control module (tach) input test and check terminal No. 20. If the wire harness is OK, substitute a known-good gauge control module (speedo) and recheck.
If any F-CAN or B-CAN communication line errors are found, go to B-CAN System Diagnosis Test mode A.
Turn the ignition switch to LOCK (0).
NOTE: If the vehicle speed exceeds 1.2 mph (2 km/h), the self-diagnostic function ends.
