If the primer fails the test, try replacing one of the following components:

1 Primer ' page 6Ć41.

2 Service Station ' page 6Ć42.

3 Cable assembly ' page 6Ć47.

4 Main PCA ' page 6Ć9.

Only replace one component at a time and perform the “Primer” test again before replacing

another component. Using this procedure you will be able to determine exactly which component

failed.
