(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / Air Conditioner / Active Test.

(e) Check the operation by referring to the table below.

Air Conditioner





OK:

Plasmacluster (ion generator) operates and mode changes.

Result:





B -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Symptom Related Diagnostic Procedures

C -- REPLACE AIR CONDITIONING AMPLIFIER ASSEMBLY Removal
A -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (PLASMACLUSTER (ION GENERATOR) - BODY GROUND)

(a) Disconnect the plasmacluster (ion generator) connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (PLASMACLUSTER (ION GENERATOR) - BATTERY)

(a) Measure the voltage according to the value(s) in the table below.

Standard Voltage:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (PLASMACLUSTER (ION GENERATOR) - A/C AMPLIFIER)

(a) Disconnect the air conditioning amplifier assembly connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. INSPECT PLASMACLUSTER (ION GENERATOR)

(a) Replace the plasmacluster (ion generator) Removal.

HINT
Since the plasmacluster (ion generator) cannot be inspected while it is removed from the vehicle, replace the plasmacluster (ion generator) with a new or a known good one and check that the condition returns to normal.

(b) Check for the DTC.

Result:





B -- REPLACE PLASMACLUSTER (ION GENERATOR) Removal

A -- REPLACE AIR CONDITIONING AMPLIFIER ASSEMBLY Removal
