1 General Information

The diagnostic information of the HVAC Occupant Climate Control (Auto A/C) system as fitted to MY 2004 AWD W agon

vehicles carries over from the information provided in Section 2F HVAC Occupant Climate Control (Auto A/C) –

Diagnostics in the MY 2003 VY and V2 Series Service Information, noting the following:

• The TECH 2 model selection procedure is as detailed in this Section.

• All MY 2004 AWD Wagon vehicles combine an OCC (Auto A/C) HVAC system with a high power (430 W) engine

cooling fan system The wiring diagram information in this Section reflects this combination.

For additional diagnosis information on MY 2004 AWD Wagon vehicles, which is not contained within this Section, refer

to following Sections as required:

• Section 2C HVAC Climate Control (Manual A/C) – Service and Diagnosis in the MY 2003 VY and V2 Series

Service Information, for HVAC components and service procedures common to Manual A/C.

• Section 2F HVAC Occupant Climate Control (Auto A/C) – Diagnostics in the MY 2003 VY and V2 Series Service

Information, for diagnostic information applicable only to OCC (Auto A/C).

3 Wiring Diagrams

The following figures provide electrical connector diagrams and a wiring diagram applicable to HVAC Occupant Climate

Control (Auto A/C) systems as fitted to MY 2004 AWD Wagon vehicle s . When diagnosin g circuit faults, these di agrams

should be used in conjunction with the diagnostic chart circuit diagrams provided in Section 2F HVAC Occupant Climate

Control (Auto A/C) – Diagnostics in the MY 2003 VY and V2 Series Service Information. The content of these figures is

as follows:

• Electrical connectors (A13 – L7) – refer to Figure 2F – 3

• Electrical connectors continued (M3 – X119) – refer to Figure 2F – 4

• Electrical connectors continued (X126 – Y37) – refer to F igure 2F – 5

• Wiring diagram – refer to Figure 2F – 6

In the following wiring diagram (Figure 2F – 6) all compo nent s are described and dis play ed in accordance to the

Integrated Vehicle Electrical Design (IVED) standard as applied to MY 2004 AWD Wagon vehicles. To assist in wiring

diagram interpretation, refer to the following table:
