DescriptionEBS011G4
When the gear position is in Neutral, park/neutral position is ON. ECM detects the position because the conti-
nuity of the line (the “ON” signal) exists.

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 ProcedureEBS011G8
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch ON.
2. Select “P/N POSI SW” in “DATA MONITOR” mode with CON-
SULT-II.
3. Check “P/N POSI SW” signal under the following conditions.
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between ECM terminal 110 and ground under the
following conditions.
