Go to step 19.

2. Perform the following steps:

a. Set your VOM to measure volts DC.

SHOCK HAZARD:

Use extreme care when checking live voltage. Do not touch live 
terminals, wires, or ground. Failure to use caution could result in 
serious electrical shock injury.

b. At P200 (A) (see figure 2-6 on page 2-27), check the voltage between 

VSS (pin 21) and the knee up function (pin 7) (see figure 3-1 on page 
3-3, and figure 3-4 on page 3-5).

Figure 2-6.  P200 Location
