It's my car. It currently hosts the whitestar equipment. It's a 2006 Toyota Corolla with a 1.4L Diesel engine. I have been collecting fuel consumption data for a while now and I have compiled a chart to summarize the fuel economy of the car as a variable of the average speed for each trip. This allows to easily distinguish between in-city and highway driving.
Also there is an MPG chart more useful for US-based viewers:
In the interest of full disclosure there is also the input data and gnuplot script to generate the charts.

Radio LAN diagnostics mode enter
To enter the LAN diagnostics mode the following steps need to be taken:
- Turn off the audio system and turn the IG switch to ACC. While pressing the preset switches ”1” and ”6” at the same time, press ”CD” 3 times.
- Reference: Beep sound is given 3 times and the system enters the service check mode. It may take about 40 sec. to complete the check.
Refer to the DIAGNOSTICS (05-599) chapter for the AUDIO SYSTEM Repair Manual for a detailed description.
In the service check mode, the system check and the diagnosis memory check are performed, and the check results are displayed in ascending order of the device codes. (physical address)
In the CQ-TS7471LC radio that I have without any external devices connected apart from the power supply the following codes are reported as "GOOD":
| Physical address | Physical label | Condition |
| P160 | AUDIO H/U | GOOD |
| P190 | AUDIO H/U | GOOD |
When the TM0461 CD Changer is connected an additional code appears:
| Physical address | Physical label | Condition |
| P160 | AUDIO H/U | GOOD |
| P190 | AUDIO H/U | GOOD |
| P360 | CD-CH1 | GOOD |
When an Aliexpress-sourced APPS2Car CD Changer emulator is connected the codes reported now are:
| Physical address | Physical label | Condition | DTC Codes | DTC Interpreted | Notes |
| P160 | AUDIO H/U | CHEC | 1L-01 1D-FF 1P-240 1N-00 1C-04 | Logical address 01 (communications ctrl) | This is only assumed as the repair manual documents a different LCD display format |
| DTC code FF | |||||
| Physical address P240 | |||||
| Connection check number 00 | |||||
| Count 04 | |||||
| P190 | AUDIO H/U | GOOD | |||
| P240 | CD-CH2 | NCON |
According to the radio repair manual the NCON condition means that the connected component has not responded to the "Diagnosis Mode ON Request" which is likely for a cheap non-brand emulator.
