Chart A-4 (Cont.):

1602 Circuit Detail:

DESCRIPTION:

In addition to address problems the combination of codes L204 and L205 could also indicate a problem with the power supply circuit 1602.

NOTES ON TROUBLE TREES:

1. This checks for voltage supply on circuit 1604. If voltage is present, each code must be diagnosed.

2. If the fuse is open, the circuit 1604 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 1604.
