COMMUNICATION NETWORK DIAGNOSTICS
Note. Before performing diagnostic procedures on module communications network, proper sequence must be used. See DIAGNOSTIC PROCEDURE SEQUENCE under COMMUNICATION NETWORK DIAGNOSTICS.
DIAGNOSTIC PROCEDURE SEQUENCE
Note. Following diagnostic procedure sequence should be followed for diagnosing module communications network.
- Verify customer's original problem. Inspect vehicle for any obvious electrical component wiring or connector damage.
- Inspect terminals in 16-terminal Data Link Connector (DLC) for damage. (Scheme 1) The DLC is a located below driver's side of instrument panel, to the right of steering column. If terminals are okay, go to next step. If terminals are damaged, repair as necessary and proceed to next step.
- Ensure transmission is in Park. Ensure all controls and switches are in the OFF position. Connect New Generation Star (NGS) scan tester to Data Link Connector (DLC).
- Check that all doors, hood and trunk are fully closed. Perform proper hook-up procedure and vehicle selection for scan tester. See «EQUIPMENT HOOK-UP»(ref-29127-S04616337732001101500000). NOTE: DO NOT touch any handle or switch that may produce a module input unless instructed to do so by the scan tester. Do not sit in driver seat while performing diagnostics.
- Perform data link diagnostics. See «DATA LINK DIAGNOSTICS»(ref-29127-S18659405082001101500000).
