Pinpoint Test A: No Communication With The Telematics Control Module

WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Be careful when probing the battery junction box (BJB), central junction box (CJB), or any connectors. Damage will result to the connector receptacle if the probe or terminal being used is too large.

CAUTION: Electronic modules are sensitive to static electrical discharges. If exposed to these charges, damage may result.

NOTE: The cellular phone module (CPM) is also referred to as the portable support electronics (PSE) module.
