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 result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
Diagnostic Procedure BBS002GA
1. CHECK OVERALL FUNCTION-I
With CONSULT-II
1. Turn ignition switch ON.
2. Select “BRAKE SW” in “DATA MONITOR” mode with CON-
SULT-II.
3. Check “BRAKE SW” indication under the following conditions.
Without CONSULT-II
Check voltage between ECM terminal 100 and ground under the fol-
lowing conditions.
