ECM Record graph4-2.
When a problem occurs in the electronic throttle system, you can display data for 2 seconds before and after the problem recorded on the ECM, for a
total of 4 seconds.
You can select the display type from 3 types of fixed patterns stored in the database. You can also select all display patterns.

Code
Refer to “Functions by model” for detailed information.
(*1) “Target TPS voltage” stands for “Target Throttle Position Sensor voltage.” This item shows the target output voltage of TPS. This value
means that ECM should control to open throttle valve to get the goal open degree.
(*2) “Target TPS voltage for ISC” stands for “Target Throttle Position Sensor voltage for Idle Speed Control.” ECM controls the engine idle
speed by using throttle valve attached TPS. This target voltage is used by ECM to achieve the goal open degree of the throttle valve
at idle speed.
(*3) “Ref. TPS voltage” stands for “Reference Throttle Position Sensor voltage.” This item shows the criterion output voltage of TPS. This
value is used to detect the TPS output voltage during engine operation.
(*4) “Ref. acc. pos. sensor voltage” stands for “Reference accelerator position sensor voltage.”
This item shows the criterion output voltage of Accelerator position sensor. This value is used to detect the Accelerator position
sensor output voltage when the remote control throttle lever opens.
