Electrical & Communication Networks
When modules drop offline or communication faults appear intermittently, we diagnose the network itself — not just the module reporting the code.
No communication with ECM, TCM, ACM, VECU/BCM and other controllers; intermittent data-link faults; modules that disappear when hot or under vibration; network-related no-start and derate conditions.
We check network voltage, resistance, termination, shorts to power or ground, opens, connector integrity and harness damage before condemning modules.
After the fault is located, we repair the affected wiring or connection, restore communication and verify that all required modules remain online under operating conditions.
GCP combines mechanical testing, electrical testing, scan-tool data and network-level diagnostics so the repair is based on evidence instead of guesswork.
