DTC Name Diagnosis Verification See D5 *1 *5 Absence of registration unit A device that the sub code shows is (was) disconnected from the system when turning the ignition switch to the ACC or ON position. The communication condition with the device that the code shows cannot be obtained when the engine starts. Inspection for the device indicated by the sub code. (Refer to the inspection list for the device indicated by the sub code.) Refer to step 6 D8 *2 *5 No response for connection check The device indicated by the sub code is (was) disconnected from the system after engine start. Inspection for the device indicated by the sub code. (Refer to the inspection list for the device indicated by the sub code.) Refer to step 6 D9 *1 *5 Last mode error The device (for audio visual system) that had functioned before the engine stopped is (was) disconnected from the system when the ignition switch is (was) in the ACC or ON position. Inspection for the device indicated by the sub code. (Refer to the inspection list for the device indicated by the sub code.) Refer to step 6 DA *5 No response against ON/OFF command No response is identified when changing mode (audio and visual mode change). Detected when sound and image do not change by switch operation. Inspection for the device indicated by the sub code. (Refer to the inspection list for the device indicated by the sub code.) Refer to step 6 DB *1 *5 Mode status error This code detects a dual alarm Inspection for the device indicated by the sub code
(Refer to the inspection list for the device indicated by the sub code.)Refer to step 6 DC *3 *5 Failure in transmission This code indicates a transmission failure to the device indicated by the sub code.
NOTE: This DTC may have no direct relationship with the malfunction.Inspection for the device indicated by the sub code.
(Refer to the inspection list for the device indicated by the sub code.)Refer to step 6 DE *4 *5 Slave reset This code is stored when a slave device has been disconnected after engine start. Inspection for the device indicated by the sub code. (Refer to the inspection list for the device indicated by the sub code.) Refer to step 6 21 ROM error This code is output when a malfunction exists in ROM. Replace multi-display MULTI-DISPLAY (CRT DISPLAY) DISPLAY 22 RAM error This code is output when a malfunction exists in RAM. Replace multi-display MULTI-DISPLAY (CRT DISPLAY) DISPLAY HINT:
- *1: This code may be recorded depending on the battery condition or engine start voltage even if no failure is detected.
- *2: If the power connector is disconnected after the engine starts, this code is recorded after 180 seconds.
- *3: This code may be stored if the ignition key is turned to the START position again with the engine running.
- *4: This code may be stored if the ignition key is held in the START position for 1 minute or more before returning to the ON position.
- *5: If the device is reported as not existing during verification, check the power source circuit and AVC-LAN circuit for the device.
