8.1.2 Signal detection and actuation
module-related parts
Cautions on Signal detection and Actuation
Module (SAM) (relay and fuse-integrated control
unit for body equipment)
The signal detection and actuation module is an
integrated unit with the control and power distribution
functions for electric parts of the cab and body
equipment.
(a) Before disconnecting the connected cables of
the signal detection and actuation module
control unit, set the starter switch of the vehicle
to OFF.
(b) Before performing welding to the chassis and
body, be sure to disconnect the signal detection
and actuation module control unit cables and
connectors. Use exteme care of spattering
(sparks, etc.) thrown on the harnesses during
the welding work.
Ground the welder near the weld.
(c) When cleaning inside the cab, take utmost care
not to splash the signal detection and actuation

actuation module control unit from the vehicle,
set the starter switch of the vehicle to OFF, then
disconnect the harness from the battery
terminals and remove the connectors/nuts in
the following order. (To reinstall, reverse the
sequence of removal.)
• Disconnect the power line (connector
No. 9C, nut No. 10C) first.
• Disconnect the control unit connectors.
• Disconnect the ground line (connector
No. 8C) last.
• Bracket nuts (back of signal detection and
actuation module, M6 x 4)]
