Troubleshooting: Wiring
ABS/ATC WIRING
Electronic Control Unit (ECU) Wiring Harness
Connectors
®
®
™
The Bendix ESP EC‑80 Controller is designed to
interface with AMP MCP 2.8 connectors as referenced in
Figure 21. Follow all AMP requirements for the repair of
wire harnesses.
All wire harness connectors must be properly seated. The
use of secondary locks is strongly advised.
All wires must be carefully routed to avoid contact
with rotating elements. Wiring must be properly
secured approximately every 6 to 12 inches using UV
stabilized, non-metallic hose clamps or bow-tie cable
ties to prevent pinching, binding or fraying.
It is recommended that wires be routed straight out of a
connector for a minimum of three inches before the wire
is allowed to bend.
Battery and ground wires should be kept to a minimum
length.
All unused ECU connectors must be covered and
receive proper environmental protection.
If convoluted tubing is used, its I.D. must match the size
of the wire bundle as closely as possible.
ABS Wiring Requirements
As a matter of good practice and to ensure maximum
system robustness, always use the maximum size wire
supported by the wire harness connectors for battery,
ignition, ground, Pressure Modulator Valve (PMV), Traction
Control Valve (TCV), Interaxle Differential Lock and
indicator lamp circuits.
All sensor and serial communications circuits (J1939) must
use twisted pair wiring (one to two twists per inch). See
the appropriate Society of Automotive Engineers (SAE)
document for additional details.
Wire harness lengths must be carefully selected for
the vehicle. Excess lengths of wire are not to be
wound to form coils, instead re-route, repair or replace
wire harness to avoid the possibility of electrical
interference and wire damage. Do not attempt to
stretch harnesses that are too short, since mechanical
strain can result in wire breakage.
Bendix® SAS-60™ Sensors and YAS-60™, or
YAS‑70X™, Sensor Wiring
If it is necessary to replace the wiring that connects the
Bendix SAS-60 or the Yaw Rate sensor to the ECU, it
is important to use the same wiring as that used by the
vehicle OEM.
