3 Diagnosis
3.1 Fault Diagnosis Charts
LT Section –
Introduction
The sunroof is operated via a control unit and a switch which is located on the roof console. The control unit and the
switch are connected to each other by two ribbon cables that each have six wires. The glass panel is activated by a drive
motor which is connected to the control unit. Battery voltage is supplied to the control unit through the ignition switch in
the ON position or a circuit breaker when the ignition switch is in the OFF position.
These tests confirm the correct operation of the sunroof and the serviceability of the switch, the control unit, the drive
motor and associated circuits. For a complete wiring diagram of the sunroof circuits, refer to 3.2 Wiri ng Di agram –
Sunroof. For connector pin locations, refer to 3.3 Connector Diagrams – Sunroof.
NOTE
The drive motor has an inbuilt thermal cut-out
device that automatically switches the motor off
during an overload condition. After a cool down
period, the motor will function normally.
NOTE
If the SCU fails and is replaced with a new unit,
the first time the new SCU is connected to the
power supply it must be calibrated, refer to
2.4 Calibrating The Sunroof Control Unit in the
VY and V2 Series Service Information.
NOTE
On completion of the electrical test and/or if the
situation arises where only the sunroof switch
button 1 and button 2 are operating, the sunroof
switch has to be reset, refer to 2.20 Sunroof
Switch in the VY and V2 Series Service
Information.
Prerequisites
Safety Requirements
When operating the sunroof as part of any of the Steps in the diagnosis charts, ensure that fingers and objects are clear
of moving parts.
Equipment
The following equipment is required to diagnose the seats:
• An unpowered test lamp with a current draw of less than 3 A
• A digital multimeter with a minimum impedance of 10 MΩ
Sunroof Page 1F2–7
Page 1F2–7
Testing Procedures
The following points must be adhered to when performing diagnostic testing on components:
1. Care must be taken when using testing equipment to diagnose wiring harness connectors. It is preferred that the
technician bac k probe the connector to avoid termi nal damage.
2. When tests are required on connector terminals, utilise the adapters in the connector adaptor kit KM–609 to
prevent damage to the terminals.
3. Unless the multimeter being used has an auto-ranging function, ensure that the correct range is selected.
4. When back-probing connectors, ensure that the test lamp earth lead is connected to a suitable earth point on the
vehicle. Ensure that this earth point is not part of the circuit being tested.
When following the Steps in the diagnosis
charts, the exact order of Steps should be
observed. If the required nominal value or
result is not achieved at any stage, the
problem must be rectified before proceeding
any further.
