KUSSMAUL 091-84-ETM62 Operational manual

Product Data Sheet
Electronic Throttle Module
Chevy/GMC Fast Idle Speed Control for Chassis
Requiring Hardwired Parking Brake Switch
The ETM62 Electronic Throttle Controller provides five
modes of engine rpm control for Chevy & GMC trucks, vans,
and buses equipped with automatic transmissions and the
following engines:
4.8 L Vortec V8 Gas
5.3 L Vortec V8 Gas
6.0 L Vortec V8 Gas
8.1 L Vortec V8 Gas
6.6 L Duramax Diesel
This controller supports GM chassis that do not provide a
parking brake position sensor message on the engine data
bus. As the system requires the parking brake to be set
before the engine speed is increased, the ETM62 controller
must be wired to the chassis parking brake switch.
Five selectable modes of fast engine idle operation include
three preset fixed speeds, a variable speed control via a
external potentiometer, and Charge Protect, which will
automatically increase engine speed to maintain the battery
charge. Ten LED indicators are provided to display the
selected operating mode, system status, and error
conditions. The ETM62 controller module is compact,
measuring only 2 x 4 inches. Wiring terminations utilize 0.25
inch Faston (blade) terminals.
The ETM62 controller mounts under the dash and is supplied
with a three foot cable that plugs into the vehicle’s OBDII
Data Link Connector. A terminal is provided to wire into the
chassis parking brake position switch.
