DIAGNOSIS

GENERAL A/C DIAGNOSTICS

Refer to Section 7B, Manual Control Heating, Ventilation, and Air Conditioning System for details of the following procedures:

V5 SYSTEM AIR CONDITIONING AND AUTOMATIC TEMPERATURE CONTROL - ATC -

Self-Diagnostic Circuit Check

The GMDAT fully automatic temperature controller (FATC) contains a self-diagnosis function to aid in finding any problem with the system. To enter the diagnostic mode, perform the following procedure:
  1. Turn the ignition to ON.
  2. Set the temperature control to 26°C (79°F).
  3. In the state of pushing the "AUTO". Push the "OFF" more than 3 times within 3 seconds.
  4. After Self-Diagnosis, if there is no error, the controller displays "00". When the controller indicates an error code, proceed to the table for that code.
  5. Push the OFF switch to return the controller to its normal functions.
