Bypassing the Rain Tracker
If you are still having trouble with the system in manual modes, try this diagnostic:
Remove the Rain Tracker interface module. Use a stiff wire to connect the BLU and GRN wires together at the Rain Tracker
interface connector. Connected this way, the wiper system should behave just as it did from the factory. If it does not, there
is some problem with the interface wiring.
3. Verify that the interface can make the wiper motor run—Pulse the Rain Tracker
activation switch.
With the ignition on, turn on the activation switch for a few seconds. Each time you do this, the wipers should run slow once.

A simple test for wiring
can eliminate problems
quickly
This test is done with the Rain Tracker module unplugged from the interface connector (J1) and
the vehicle on.
For HSS applications:
Using a stiff wire as a jumper, on the Rain Tracker connector, connect YEL to BLU. Wired
correctly, the wipers will run slow.
To check fast, connect YEL to PNK. Wired correctly, the wipers will run fast.
Since the module is unplugged, the wipers will not run home. You can plug in the module to run
the wipers back home.
For GSS applications:
Using a stiff wire as a jumper, on the Rain Tracker connector, connect WHT to BLU. Wired
correctly, the wipers will run slow.
To check fast, connect WHT to PNK. Wired correctly, the wipers will run fast.
If you do not get the expected result, check the corresponding wires. Check the connection on
the BLU wire. Also, check the connection on the YEL (WHT on GSS applications) which
connects to the RED power wire (GND wire for GSS applications).
If you get the expected results, please proceed with the procedure.

You probably have a problem with the power, ground, or activation switch.
Check to see that the activation switch is working: there should be about 12V at the activation
switch / mode reader (GRY wire) coming into the Rain Tracker.
