If there is no movement from the ortho wiper, then the test has failed. To resolve the problem, try

replacing one of the following components:

1 Service Station  page 6Ć42.

2 Cable assembly  page 6Ć47.

3 Main PCA  page 6Ć9.

Only replace one component at a time and perform the “Ortho Wiper” test again before

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

component failed.
