Display Diagnosis
Vehicle Signals
A comparison check can be made of each actual vehicle signal and the signals recognized by the system.
| Diagnosis item | Display | Vehicle status | Remarks |
|---|---|---|---|
| Vehicle speed | ON | Vehicle speed > 0 km/h (0 MPH) | Changes in indication may be delayed. This is normal. |
| OFF | Vehicle speed = 0 km/h (0 MPH) | ||
| Parking brake | ON | Parking brake is applied. | |
| OFF | Parking brake is released. | ||
| Lights | ON | Light switch ON | - |
| OFF | Light switch OFF | ||
| Ignition | ON | Ignition switch ON | - |
| OFF | Ignition switch in ACC position | ||
| Reverse | ON | Shift the selector lever to "R" position | Changes in indication may be delayed. This is normal. |
| OFF | Shift the selector lever other than "R" position |
Speaker Test
Select "Speaker Test" to display the Speaker Diagnosis screen. Press "Start" to generate a test tone in a speaker. Press "Start" again to generate a test tone in the next speaker. Press "End" to stop the test tones.
Climate Control
Refer to AUTOMATIC AIR CONDITIONING CONTROL SYSTEM (CONVERTIBLE) for details.
Error History
The self-diagnosis results are judged depending on whether any error occurs from when "Self-diagnosis" is selected until the self-diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has occurred before the ignition switch is turned ON and then no error has occurred until the self-diagnosis start. Check the "Error Record" to detect any error that may have occurred before the self-diagnosis start because of this situation.
The frequency of occurrence is displayed in a count up manner. The actual count up method differs depending on the error item.
Count up method A
- The counter resets to 0 if an error occurs when ignition switch is turned ON. The counter increases by 1 if the condition is normal at a next ignition ON cycle.
- The counter upper limit is 39. Any counts exceeding 39 are ignored. "The counter can be reset (no error record display) with the Delete log" switch or CONSULT.
Count up method B
- The counter increases by 1 if an error occurs when ignition switch is ON. The counter will not decrease even if the condition is normal at the next ignition ON cycle.
- The counter upper limit is 50. Any counts exceeding 50 are ignored. "The counter can be reset (no error record display) with the Delete log" switch or CONSULT.
| Display type of occurrence frequency | Error history display item |
|---|---|
| Count up method A | CAN communication line, control unit (CAN), AV communication line, control unit (AV) |
| Count up method B | Other than the above |
