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
ABS002IL
1.
CHECK GROUND CONNECTIONS
1.
Turn ignition switch OFF.
2.
Loosen and retighten two ground screws.
Refer to
