manual. REFER to: (501-17 Roof Opening Panel)
Roof Opening Panel (Description and Operation), Roof Opening Panel (Description and Operation), Roof Opening Panel (Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.
Visual Inspection
Mechanical Electrical
Roof opening panel
Helixed drive cables
Switch
Control unit/motor
Fuses/relays (refer to electrical guide)
Wiring harness
Correct engagement of electrical connectors
Loose or corroded connections
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
DTC Index
CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to
the installation of a new module/component.
Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give extra information read by
the manufacturer-approved diagnostic system).
When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal places and
with a current calibration certificate. When testing resistance, always take the resistance of the DMM leads into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
