A-3 (Continued) 1600 Power Circuit Problem

Chart A-3 (Cont.):

1600 Circuit Detail:

DESCRIPTION:

In addition to address problems, the combination of codes L202 and L203 could also indicate a problem with the power supply circuit 1600.

NOTES ON TROUBLE TREES:

1. This checks for voltage supply on circuit 1600. If voltage is present, each code must be diagnosed separately.

2. If the fuse is open, the circuit 1600 must be checked for a short to ground.

3. If the fuse is OK, there is an open or short to ground in the voltage supply (circuit 2) to the fuse or an open in circuit 1600.
