General Module: Testing and Inspection
Check the Wake-Up Function
Check the wake-up lines:
Check for continuity of each line. There should be continuity.
-
If there is no continuity, the line is open.
-
If there is continuity, go to next step.
Check for voltage between each control units with the wake-up lines connected. There should be no voltage in the wakeup mode, and there should be
battery voltage in the sleep mode.
If the voltages are not specified, disconnect the wake-up line connector of one control unit, and recheck. Then connect it, and disconnect the wake up
line connector of another control unit, and recheck.
-
If the voltage are not specified on both sides of the line, the wake-up line is shorted to another wire or body ground.
-
If the voltages are not specified on one side of the line, inspect the connector and socket terminals to be sure they are all making good contact. If
the terminals are OK, the possible cause is a disconnected wake-up line in the control unit.
