Pathfinder XE 2WD V6-3.3L (VG33E) (1997)
Relationship Between Open/Short (high Resistance) Circuit And The ECU Pin Control: Case 1
Relationship between open/Short (high resistance) circuit and the ECM pin control
System Description: When the switch is ON, the Engine control module (ECM) lights up the lamp.
Input-output Voltage Chart
*:If high resistance exists in the switch side circuit (caused by a single stand), terminal 1 does not detect battery voltage. ECM does not detect the
switch is ON even if the switch does turn ON. Therefore, the ECM does not supply power to light up the lamp.
Relationship Between Open/Short (high Resistance) Circuit And The ECU Pin Control: Case 2
Input-output Voltage Chart
*:If high resistance exists in the switch side circuit (caused by a single stand), terminal 2 does not detect approx. 0 V. ECM does not detect the
switch is ON even if the switch does turn on. Therefore, the ECM does not control ground to light up the lamp.
