DIAGNOSIS AND TESTING
PRINCIPLE OF OPERATION
For a detailed description of the exterior lighting system and operation,
refer to the relevant description and operation
section of the workshop manual. REFER to: Exterior Lighting (Exterior Lighting,
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 checked and/or
the donor vehicle
NOTES:
- If the control module or a component may be at fault and the vehicle
remains under manufacturer
warranty, refer to the Warranty Policy and Procedures manual (section B1.2),
or determine if any prior
approval program is in operation, prior to the installation of a new
module/component.
- When performing voltage or resistance tests, always use a digital
multimeter accurate to three decimal
places, and with an up-to-date calibration certificate. When testing
resistance, always take the resistance
of the digital multimeter leads into account.
- Check and rectify basic faults before beginning diagnostic routines
involving pinpoint tests.
- Verify the customer concern
- Visually inspect for obvious signs of mechanical or electrical damage
Visual Inspection
- If an obvious cause for an observed or reported concern is found,
correct the cause (if possible) before
proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to
the symptom chart, alternatively check for
diagnostic trouble codes (DTCs) and refer to the relevant DTC index
- Check JLR claims submission system for open campaigns. Refer to the
corresponding bulletins and SSMs
which may be valid for the specific customer complaint and complete the
recommendations as required
