ELECTRONIC THROTTLE CONTROL

ETC OVERVIEW

NOTICE
DO NOT attempt to service the ETC. The ETC is a non-
serviceable component and can only be tested using
Digital Wrench®. If the ETC is faulty, the entire
assembly must be replaced.
Mounted to the intake, the ETC acts as an electronically
controlled throttle body. The ETC controls engine throttle
operation to provide the proper air/fuel ratio needed for
engine operation at all RPM ranges. The ETC controls
engine RPM based off input provided by the Throttle
Control Sensor (TCS) and Electronic Control Unit (ECU).

ETC TEST

IMPORTANT
Never attempt to disassemble the ETC assembly.
Warranty is void if the end cover is opened or tampered
with in any way.
All operating and control functions within the ETC are
pre-set. No internal servicing or adjustments may be
performed. If a problem is encountered, and you
determine the ETC to be faulty, contact the TAYLOR-
DUNN Service Department
instructions. Do not replace the ETC without factory
authorization.
Use Digital Wrench® to perform all troubleshooting of
this component. Use a Volt Ohm meter to test the vehicle
harness continuity between the ETC connector and ECU
connector. Refer to the wire diagram for pin-out details. If
the ETC is faulty, the entire ETC assembly must be
replaced.
