DIAGNOSTIC TROUBLE CODE CHART
HINT: If any DTCs are simultaneously output for 2 or more slave units that are connected in series, there may be a problem between the master unit and the slave unit which is closest to the master unit. Therefore, first proceed with troubleshooting of that slave unit.
For example, if DTCs are output for the television camera ECU and multi-display controller sub-assy, there may be a problem between the master unit and television camera ECU. (Refer to the illustration below.)
HINT: Titles for each unit are stated in the following order: parts name (physical address) [Name indicated by DTC]
1. MULTI-DISPLAY (physical address: 110) [EMV]
a. Logical address: 01 (Communication control)
b. Logical address: 21 (SW): 23 (SW with name): 24 (SW converting): 25 (command SW)
2. NAVIGATION ECU (Physical address: 178) [NAVI]
NOTE: The following inspection procedures of the navigation ECU are described on the assumption that the television camera ECU (w/o RSE) or multi-display controller sub-assy (w/ RSE) is normal.
If any television camera ECU (w/o RSE) DTC or multi-display controller sub-assy (w/ RSE) DTC is output, first proceed with troubleshooting of the television camera ECU (w/o RSE) or multi-display controller sub-assy (w/ RSE). (Refer to step 5 or 7.)
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
b. Logical address: 58 (Navigation): 80 (GPS)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
3. RADIO RECEIVER ASSY (Physical address: 190) [AUDIO H/U]
NOTE: Only w/ RSE System:
The following inspection procedures of the radio receiver assy are described on the assumption that the multi-display controller sub-assy is normal.
If any multi-display controller sub-assy DTC is output, first proceed with troubleshooting of the multi-display controller sub-assy. (Refer to step 7.)
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
b. Logical address: 01 (Communication control)
c. Logical address: 62 (CD): 63 (In-dash CD changer)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
d. Logical address: 61 (Cassette)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
4. GATEWAY ECU (Physical address: 1C6) [G/W]
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
HINT: This code is stored 210 seconds after the power supply connector of the master component is disconnected with the ignition switch in the ACC or ON position.
5. TELEVISION CAMERA ECU (Physical address: 280) [CAMERA]
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
b. Logical address: 5C (Camera)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
6. STEREO COMPONENT AMPLIFIER ASSY (Physical address: 440) [DSP AMP]
NOTE: The following inspection procedures of the stereo component amplifier assy are described on the assumption that the radio receiver assy is normal.
If any radio receiver assy DTC is output, first proceed with troubleshooting of the radio receiver assy. (Refer to step 3.)
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
7. MULTI-DISPLAY CONTROLLER SUB-ASSY (Physical address: 1F6) [RSE ECU]
NOTE: The following inspection procedures of the multi-display controller sub-assy are described on the assumption that the television camera ECU is normal.
If any television camera ECU DTC is output, first proceed with troubleshooting of the television camera ECU. (Refer to step 5.)
a. Logical address: 01 (Communication control)
HINT: Methods used to verify the cause of the problem are listed in order of probability in the verification column.
8. THE INSPECTION LIST FOR THE DEVICE INDICATED BY THE SUB CODE
HINT:
- If any DTCs are output for 2 or more slave units that are connected in series, there may be a problem between the master unit and the slave unit which is closest to the master unit. Therefore, first proceed with troubleshooting of that slave unit.
- Methods used to verify the cause of the problem are listed in order of probability in the verification column.
