Navigation Communication Line Circuit Troubleshooting
- Operate the climate control system in several modes.
Is the climate control system OK?
YES -Go to step 2.
NO -Do the self-diagnostic function with the HDS (see HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITH THE HDS ) or the climate control unit (see HOW TO USE THE SELF-DIAGNOSTIC FUNCTION WITHOUT THE HDS ).
- Do the Navi system link, '07-09 models (see
START-UP PROCEDURE AND DIAGNOSIS MENU
), '10-11 models (see
SYSTEM DIAGNOSTIC MODE - ('10-11 MODELS)
).
Is the Air-Con or TALK/BACK icon red?
YES -
- If Air-con icon is red, go to step 3.
- If TALK/BACK icon is red, go to "voice control does not work" in the navigation system symptom troubleshooting, '07-09 model (see VOICE CONTROL DOES NOT WORK/RESPOND ), '10-11 models (see VOICE CONTROL DOES NOT WORK/RESPOND ).
NO -Go to 11.
- Turn the ignition switch to LOCK (0).
- Disconnect audio-navigation unit connector F (5P) ('07-09 models), or D (12P) ('10-11 models).
- Disconnect the climate control unit 36P connector.
- '07-09 models: Check for continuity between the following terminals of the climate control unit 36P connector and audio-navigation unit connector F (5P).
36P: 5P:
No. 3 No. 2
No. 4 No. 4
No. 5 No. 3

Is there continuity?
YES -Go to 8.
NO -Repair an open in the wire(s) between the climate control unit and the audio-navigation unit.
- '10-11 models: Check for continuity between the following terminals of the climate control unit 36P connector and audio-navigation unit connector D (12P).
36P: 12P:
No. 3 No. 12
No. 4 No. 6
No. 5 No. 5

Is there continuity?
YES -Go to step 8.
NO -Repair an open in the wire(s) between the climate control unit and the audio-navigation unit.
- '07-09 models: Check for continuity between body ground and audio-navigation unit connector F (5P) terminals No. 2, 3, and No. 4 individually.Fig 3: Checking Continuity Between Body Ground And Audio-Navigation Unit Connector F (5P) Terminals No. 2, 3 And No. 4

Is there continuity?
YES -Repair a short to body ground in the wire(s) between the climate control unit and the audio-navigation unit.
NO -Go to 10.
- '10-11 models: Check for continuity between body ground and audio-navigation unit connector D (12P) terminals No. 5, 6, and No. 12 individually.Fig 4: Checking Continuity Between Body Ground And Audio-Navigation Unit Connector D (12P) Terminals No. 5, 6 And No. 12

Is there continuity?
YES -Repair a short to body ground in the wire(s) between the climate control unit and the audio-navigation unit.
NO -Go to step 10.
- Reconnect the climate control unit 36P connector.
- Disconnect audio-navigation unit connector F (5P) ('07-09 models) or D (12P) ('10-11 models).
- '07-09 models: Connect audio-navigation unit connector F (5P) No. 2, 3, and No. 4 terminals with a jumper wire.
- '10-11 models: Connect audio-navigation unit connector D (12P) terminals No. 5, 6, and No. 12 with a jumper wire.
- Turn the ignition switch to ON (II).
- Press and hold the AUTO and OFF buttons.
Does the VENT and HEAT indicator turn on?
YES -Do the audio-navigation unit check, '07-09 models (see UNIT CHECK ), '10-11 models (see UNIT CHECK (QUICK CHECK) ).
NO -Substitute a known-good climate control unit, and recheck. If the symptom goes away, replace the original climate control unit (see CLIMATE CONTROL UNIT REMOVAL/INSTALLATION ).
