TROUBLESHOOTING
GENERAL
While the EC-15 ™ controller diagnostic display locates a
specific problem area, it is still necessary to confirm whether
the problem resides in the component itself or the wiring.
Basically the troubleshooting procedure that follows is
devoted to narrowing the problem to either the wiring or a
specific antilock component.
TROUBLESHOOTING TIPS
1. All troubleshooting begins by observing the antilock
condition lamp on the dash. Troubleshooting should
begin by first performing the “Initial Start-up Procedure”
and following the directions contains in it.
2. The troubleshooting technician should record all findings
and the action taken during the troubleshooting process.
3. No voltage or resistance tests are performed into the
EC-15 ™ controller. All voltage and resistance tests are
performed by beginning at the wire harness half of the
connector and moving AWAY from the EC-15
™ controller
toward an antilock system component (modulator, wheel
speed sensor, etc.)
