TSB : Test Description
Engine Performance
Details
NOTE: Test numbers refer to test numbers on diagnostic chart. Glowing test light indicates that battery voltage and continuity through TCC Solenoid are okay. Checks for vehicle speed sensor (VSS) signal to ECM, using a "SCAN" tester. Checks for 4th gear signal to ECM. This signal will not prevent TCC engagement, but could cause a change in engage/disengage speed points.
