Aerio AWD L4-2.0L (2003)
b. Also, if measured values were as listed in the following, it means that there is a resistance (abnormality) of such level that corresponds to the
voltage drop in the circuit between terminals A-1 and B-1.
Voltage between
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: Approx. 3 V
Short Circuit Check (wire harness to ground)
1. Disconnect negative (-) cable at battery.
2. Disconnect connectors at both ends of the circuit to be checked.
NOTE: If the circuit to be checked is connected to other parts (1), disconnect all connectors of those parts. Otherwise, diagnosis will be misled.
3. Measure resistance between terminal at one end of circuit (A-1 terminal in the figure) and body ground. If continuity is indicated, it means that
there is a short to ground between terminals A-1 and C-1 of the circuit.
4. Disconnect the connector included in circuit (connector B) and measure resistance between A-1 and body ground. If continuity is indicated, it
means that the circuit is shorted to the ground between terminals A-1 and B-1.
Intermittent and Poor Connection Inspection
Intermittent and Poor Connection Inspection
Most intermittent are caused by faulty electrical connections or wiring, although a sticking relay or solenoid can occasionally be at fault. When checking
it for proper connection, perform careful check of suspect circuits for:
-
Poor mating of connector halves, or terminals not fully seated in the connector body (backed out).
