Go to Step 2 Go to Diagnostic System Check - Vehicle in Vehicle DTC Information 2 Are DTCs B3717 or B3718 stored in the body control module (BCM)? Go to DTC B3715, B3716, B3717, B3718, or B3719 Go to Step 3 1. Turn ON the ignition Attempt to operate the wipers in each mode. Do the windshield wipers operate correctly in any mode? Go to Step 4 Go to Wipers Inoperative - All Modes 4 Turn the wiper switch to the high speed position.do the windshield wipers operate at high speed? Go to Step 5 Go to Step Turn the wiper switch to the low speed position Wait 5 seconds. Do the windshield wipers operate at low speed after 5 seconds? Go to Step 6 Go to Step Turn the wiper switch through each delay position.do the windshield wipers operate correctly in each delay position? Go to Step 7 Go to Step 33 Turn the wiper switch to the mist position.do the windshield wipers operate at low speed? Go to Step 8 Go to Step 33 8 Turn the wiper switch to the wash position.do the windshield wipers operate at low speed? Go to Testing for Intermittent Conditions and Poor Go to Step 11

2 2 of 6 2/1/2015 8:12 PM Connections in Wiring Systems 9 1. Turn the wiper switch to the low speed position. 2. Observe the Wiper Delay Input parameter with a scan tool. Is the Wiper Delay Input equal to 0.00 volts? Go to Step 21 Go to Step Observe the Wiper Relay Cmd. parameter with a scan tool.is the Wiper Relay Cmd. ON? Go to Step 13 Go to Step Turn the wiper switch to the wash position. 2. Observe the Washer Switch parameter with a scan tool. Is the Washer Switch ON? Go to Step 35 Go to Step Disconnect the windshield wiper motor Jumper the windshield wiper motor park switch signal circuit to a good ground with a 3-amp fused jumper. Refer to Using Fused Jumper Wires in Wiring Systems. 3. Observe the Wiper Park Switch parameter with a scan tool. Is the Wiper Park Switch Active? Go to Step 32 Go to Step Disconnect the windshield wiper motor Probe the windshield wiper motor low speed circuit with a test lamp connected to a good Does the test lamp illuminate? Go to Step 32 Go to Step Remove the wiper 2 relay from the underhood fuse block. Refer to Relay Replacement (Within an Electrical Center) or Relay Replacement (Attached to Wire Harness) in Wiring Systems. 2. Probe the wiper 2 relay voltage Go to Step 24 Go to Step 23

Disconnect the windshield wiper motor Turn the wiper switch to the high speed position. 3. Probe the windshield wiper motor high speed circuit with a test lamp connected to a good Does the test lamp illuminate? Go to Step 32 Go to Step Remove the wiper 2 relay from the underhood fuse block. Refer to Relay Replacement (Within an Electrical Center) or Relay Replacement (Attached to Wire Harness) in Wiring Systems. signal 2 circuit from the wiper switch Does the test lamp illuminate? Go to Step 17 Go to Step Connect a test lamp between the windshield wiper switch signal 2 circuit from the wiper switch and the wiper 2 relay coil ground circuit.does the test lamp illuminate? Go to Step 18 Go to Step 34 Probe the wiper 2 relay voltage supply circuit Does the test lamp illuminate? Go to Step 24 Go to Step Remove the wiper diode from the underhood fuse block. 19 signal 2 circuit from the wiper switch Does the test lamp illuminate? Go to Step 31 Go to Step Disconnect the BCM. 2. Probe the windshield washer pump Go to Step 35 Go to Step 29

4 4 of 6 2/1/2015 8:12 PM control circuit from the wiper switch Does the test lamp illuminate? 1. Disconnect the BCM. 21 signal 1 circuit with a test lamp connected to a good Does the test lamp illuminate? Go to Step 35 Go to Step Disconnect the underhood fuse block J7 connector. 22 signal 2 circuit from the wiper switch Does the test lamp illuminate? Go to Step 34 Go to Step Disconnect the underhood fuse block J7 connector. 23 signal 2 circuit from the BCM with a test lamp connected to a good Does the test lamp illuminate? Go to Step 34 Go to Step Test the windshield wiper motor high and low speed circuits for an open or a high resistance. Refer to Circuit Testing andwiring Repairs in condition? Go to Step 42 Go to Step 30 Test the windshield wiper switch signal 1 circuit for an open or a high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.Did you find and correct the condition? Go to Step 42 Go to Step 33 Test the windshield wiper switch signal 2 circuit from the wiper switch for an open or a high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.Did you find and correct the condition? Go to Step 42 Go to Step Test the windshield wiper switch signal 2 circuit from the BCM for an open or a high resistance. Go to Step 42 Go to Step 35

5 5 of 6 2/1/2015 8:12 PM Refer to Circuit Testing andwiring Repairs in condition? Test the windshield wiper motor park switch signal circuit for an open or a high resistance. Refer to Circuit Testing andwiring Repairs in condition? Go to Step 42 Go to Step 35 Test the windshield washer pump control circuit from the wiper switch for an open or a high resistance. Refer to Circuit Testing andwiring Repairs in Wiring Systems.Did you find and correct the condition? Go to Step 42 Go to Step 33 Inspect for poor connections at the wiper 2 relay. Refer to Testing for Intermittent Conditions and Poor Connections andconnector Repairs in Wiring Systems.Did you find and correct the condition? Go to Step 42 Go to Step 36 Inspect for poor connections at the wiper diode. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in condition?
