Electrical analysis
Check using the YDIS
When checking the TPS, APS, or other sen-
sors, use the YDIS.
When deleting the diagnosis record in the
YDIS, be sure to check the time that the diag-
nostic codes were detected.
When checking the input voltage of a part, the
coupler or connector must be disconnected.
As a result, the ECM determines that the part
is disconnected and a diagnostic code is
detected. Therefore, be sure to delete the
diagnosis record after checking the input volt-
age.
Power is supplied to the ECM for about 30
seconds after stopping the engine. Therefore,
wait longer than 30 seconds before restarting
the engine, otherwise the diagnostic codes will
not be cleared from the ECM.
NOTE:
• Before checking the electrical components,
make sure that the battery is fully charged.
• If the tester leads are connected while using
the YDIS, diagnostic codes will be detected.
• If a diagnosis record is displayed and it is
caused by the checking steps, delete the
record by using the
“ Diagnosis record ” func-
tion of the YDIS.
• The YDIS requires that you use an exclusive
communication cable and CD-ROM to con-
nect to a computer. For a description of the
communication cable and CD-ROM to be
used, refer to
“ YDIS ” in Chapter 9. Also, be
sure to check the CD-ROM version before
using it.
• To connect the YDIS, refer to “ YDIS ” in
Chapter 9 or the YDIS (Ver. 1.30) Instruction
Manual.
