TROUBLE DIAGNOSIS Ð GENERAL DESCRIPTIONYD25DDTi
ECM Terminals and Reference Value
(Cont'd)
EC-3466

Description
The stop lamp switch is installed to brake pedal bracket. The
switch senses brake pedal position and sends an ON-OFF sig-
nal to the ECM. The ECM uses the signal to control the fuel
injection control system.
ECM Terminals and Reference Value
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may damage the
ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch ªONº.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Depress and release brake pedal more than 10 times.
4) If DTC is detected, go to ªDiagnostic Procedureº, EC-3588.
WITHOUT CONSULT-II
1) Turn ignition switch ªONº.
2) Depress and release brake pedal more than 10 times.
3) Turn ignition switch ªOFFº, wait at least 5 seconds and then
turn ªONº.
4) Perform ªDiagnostic Test Mode II (Self-diagnostic results)º
with ECM.
5) If DTC is detected, go to ªDiagnostic Procedureº, EC-3588.SEF817Y
