TEST PROCEDURE 26 – 4-Pin Connector (for Connected Car Device)
See General Warnings on page 1-1.
NOTE: This is a voltage and continuity test.
The Connected Car Device 4-pin connector is used for Guardian/Visage and is labeled “V3 circuit” on the
main wire harness.
Pin 1 – Black Pin 4 – Open
Pin 2 – Red Pin 3 – Open
2786
Figure 18-26 4-Pin Connector
1. If necessary, see Testing Basics.
2. Set the multimeter to 200 Ohms.
3. Check for continuity between pin 1 (black wire) of the 4-pin connector (Figure 18-26, Page 18-41) and pin 18
(black wire) of the black 18-pin connector on the ECU.
3.1. If there is continuity, go to the next step.
3.2. If there is no coninuity, check sonic welds 4, 10, and 14. Proceed to the next step.
4. Set the key switch to ON.
5. Set the multimeter to 20 VDC.
6. Check for battery voltage at pin 2 (red wire) of the 4-pin connector.
6.1. If there is battery voltage, go to the next step.
6.2. If there is no voltage, check the 2-amp fuse located near the 4-pin connector. See following NOTE.
NOTE: The red wire only has battery voltage with the key switch in the ON position.
6.3. If the 2-amp fuse is good, check the 5-amp fuse located near the electrical box.
7. Set the key switch to ON.
8. Set the multimeter to 20 VDC.
9. Check the voltage at pin 4 (blue wire) of the 4-pin connector. See following NOTE.
NOTE: The blue wire only has voltage with the key switch in the ON position.
9.1. If the voltage is approximately 11.8 volts, the 4-pin connector circuit is good.
