ABOUT THE WIRING MANUAL
The wiring manual outlines complete electrical network plan of the Mahindra XYLO mEagle vehicle,
fitted with AIRBAGS.
The wiring plan for XYLO mEagle (Airbag) version is different from the XYLO mEagle (non-airbag)
version in view of the extensive use of CAN in the Airbag version. Please ensure the correct wiring manual
is used while diagnosing XYLO mEagle vehicles fitted with Airbags
Wiring diagrams are technical drawings representing the electrical /electronic structure of the vehicle.
Understanding this manual is the quickest way to identify and repair a trouble, first time right. The manual
defines as to how the various systems are integrated and works, functions and operates. All the electrical
components are shown, including their locations, colors of connecting wires and connectors.
The manual is structured as below –
Component locations – Indicates schematically the location of the crucial components like fuses,
relays and controllers (ECUs)
In-vehicle communication network – Details the data communication network within various
controllers in the vehicle through LIN, K-Line and CAN.
Harness Layout – Indicates the physical layout of the wiring harness across the topography of the
vehicle. It also indicates the connectors and their codes/locations.
Inter-harness Connectors – Specifies the code, locations and pin-out view of the connectors in
between separate wiring harnesses.
Terminal Connectors –Specifies the code, locations and pin-out view of the major connectors which
terminate at controllers (ECUs)
Ground Points – Specifies the locations of the various grounding points across the vehicle body/chasis.
Circuit Plans – Specifies the circuit diagram of individual circuits, function wise.

Good electrical/electronic troubleshooting process
When troubleshooting any problem related to electrical/electronic system, follow the 5-step
process –
STEP 1 – Verify the customer complaint
•Turn on all the component/functions in the problem circuit to check accuracy of the
customer complaint.
•Replicate the customer complaint
•Note down the symptoms
•Do not begin disassembly or testing unless you have narrowed down the probable causes.
STEP 2 – Read and analyze the wiring diagrams
•Locate the specific circuit diagram of the problem circuit
•Understand how the circuit is supposed to work by tracing the circuit from power source
through components on to ground.
•Check other circuits which share components/fuse/ground/switch with this circuit.
•Isolate the circuit/component with problem.
STEP 3 - Inspect circuit/component with problem isolated
•Make a circuit test to check the diagnosis
•Narrow down the probable causes using troubleshooting charts/diagnosis charts
STEP 4 – Repair the problem
•Make necessary repairs as authorized
STEP 5 – Re-check the circuit
•Repeat the system check to ensure that the problem is eliminated
•Check related circuits
•Ensure that the customer symptom is eliminated
