d. CABLE CONNECTORS.
The four cable connectors on the VTM are DCA/PWR J1, transducer cable
connectors J2 TK and J3 TK, and VOLTS/OHMS J4.
DCA/PWR connector J1 used to connect VTM to either a vehicle
diagnostic connector with the DCA cable W1 or to a DC power source
with the power cable W5. The DC power source is usually the vehicles
Transducer cable connectors J2 TK and J3 TK used to connect transducer
cables W4 to VTM. Power and signals are routed through these
connectors. Both connectors may be used when a test requires two
measurements to be made at the same time.
VOLTS/OHMS connector J4 used to connect test probe cable W2 to
VTM for voltage and resistance tests.
