Figure 18-26 4-Pin Connector
1. If necessary, see Testing Basics on page 18-14.
2. Check for continuity between pin 1 (black wire) (Figure 18-26, Page 18-43) and pin 18 (black wire) of the black
18-pin connector on the ECU. It should indicate continuity. If not, check sonic welds no. 4, 10, and 14.
3. Probe pin 2 (red wire). It should show battery voltage with the key switch in the ON position. If not, check 2-amp
fuse near 4-pin connector. See following NOTE.
NOTE: The red wire only has battery voltage with the key switch in the ON position.
4. Probe pin 4 (blue wire). It should show approximately 11.8 volts supplied by pin 8 (blue/white wire) of the black
18-pin connector on the ECU. If not, check wiring and then ECU. See following NOTE.
NOTE: The blue wire only has voltage with the key switch in the ON position.
If pin 4 has no voltage, the ECU LIN (Local Interconnect bus) may have failed. The vehicle can be driven if it
is not used with Guardian or Visage and will not show any symptoms. Otherwise, Guardian or Visage will
disable the vehicle until communication is restored.
