NOTE:
Test numbers refer to numbers on diagnostic chart.
- Checks if fault is due to cruise control servo or circuit. Frequency should cycle between zero and a non-zero number. If DVOM stays at zero, circuit or PCM is at fault.
- Checks for short to voltage in circuit No. 205.
- Checks for open in circuit No. 451.
