Air Source Selection Not Controlled: Notes

WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Pressure-Temperature Relationship of R-134a for the electrical schematic diagram of the circuits described in this procedure.

DIAGNOSTIC PROCEDURE

Step	Action	Value(s)	Yes	No
1	Measure the voltage at terminal 4 of the intake motor. Is the voltage within the value specified?	11 - 14 V	Go to Step 3	Go to Step 2
2	Check the connector and circuit BRN for any wiring or terminal problems. Repair any problems found. Is the repair complete?	-	System OK	-
3	Using the Intake Motor Table, measure the voltages at the specified terminals of the motor connector. Change the intake setting and observe the voltage changes. Are these voltages within the specified value?	See the Intake Control Table .	Go to Step 4	Go to Step 5
4	Replace the intake motor. Is the repair complete?	-	System OK	-
5	Using the Intake Motor Table, measure the voltages at the specified terminals of the controller connector. Change the intake setting and observe the voltage changes. Are these voltages within the specified value?	See the Intake Control Table .	Go to Step 6	Go to Step 7
6	Check the wiring harness and connectors between the controller and the motor that is not performing properly. Repair or replace the wiring harness or the defective terminal. Is the repair complete?	-	System OK	-
7	Check the connector at the controller. Is there a defective terminal?	-	Go to Step 8	Go to Step 9
8	Repair or replace the terminal. Is the repair complete?	-	System OK	-
9	Replace the controller. Is the repair complete?	-	System OK	-
