Is there 0 V or about 5 V?
1. YES -Check for loose terminal fit in the TCM connectors. If necessary, substitute a known-good TCM (see HOW TO TROUBLESHOOT CIRCUIT AT THE TCM ) and recheck.
2. NO -Check for an open or a short in the wire between TCM connector terminal B5 and the vehicle speed sensor (VSS). If the wire is OK, replace the VSS.
