NOTE:
Test numbers refer to numbers on diagnostic chart.
- This chart should be used after verifying proper operation of PCM and circuits.
- At this point, no current electrical faults exist. Under normal operating conditions, VCC and VCC MOD indicator will come on at same time VCC applies; VCC MOD indicator will flash briefly and go out. At this time, VCC is in full apply. VCC test should be run with A/C off since A/C cycling can affect engine RPM.
- If VCC does not engage or disengage under control of Transmission Break Out Box (J-38791), diagnosis of transmission is indicated.
