Inspect the regulated voltage in the following procedures:
| Note when making this test, be sure that the battery is in fully charged condition. |
Special tool
(a): 09900–25008 (multi circuit
tester set)
Tester knob indication

Ecm stores the engine and driving conditions (in the form of data as shown in
the figure) at the moment of the
detection of a malfunction in its memory. This data is called “show data when
trouble”.
Therefore, it is possible to know engine and driving conditions (e.G., Whether
