5.1.1
Signal detection and actuation modulerelated parts
Work carried out incorrectly on the electrical system may impair its function. This may lead to the failure of components or parts relevant to safety.
Cautions on Signal detection and Actuation Module (SAM) (relay and fuse-integrated control unit for body equipment)
All accident prevention regulations must be complied with when working on the vehicle.
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.
Comply with all national regulations and laws.
a Risk of fire Work on live electrical lines carries a risk of short circuit. Before starting work on the electrical system, disconnect the on-board electrical system from the power source, e.g. battery.
i Observe the notes on operating safety and vehicle safety in Section 1 "Introduction" e page 10 and e page 11.
(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 module control unit (including relays, fuses and connectors) with water. (d) When removing the signal detection and 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)] When installing the signal detection and actuation module control unit to the vehicle, tighten its nuts to the torques specified below.
