DIAGNOSING AND LOCATING A SYSTEM

DIAGNOSTIC TROUBLE CODE

GENERAL

The EC-17

™

controller contains self test and diagnostic

circuitry that continuously checks for proper operation of the

entire antilock/traction system, including wiring continuity.

The EC-17

™

& EC-17N

™

controllers are programmed at the

factory to accommodate the needs of the vehicle and the

customer’s desires. Both the EC-17

™

& EC-17N

™

controller

can be reconﬁ gured by the end user to include traction

control (See the Important notice concerning the EC-17N

™

controller). A vehicle equipped with traction control can

generally be identiﬁ ed by noting the presence of a dash

mounted condition lamp, a disable switch (for the traction

control system) and a traction solenoid located above the

relay valve.
