Diagnostic Aids

WARNING: This page is about a different car, the 2003 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Inspect wiring harness for damage. Check for broken or chaffed insulation.
If fault is suspected to be intermittent, wiggling harness wiring may help in locating fault.
Check for poor connection at the BCM. Inspect harness connectors for backed out terminals, improper terminal mating, broken connector locks, improperly formed or damaged terminals and poor terminal-to-wire connection (terminal crimped over wire insulation and not conductors).

DTC B3703

Step	Action	Yes	No
Connector End View Reference: Master Electrical Component List in Wiring Systems
1	Did you perform the Wiper/Washer Diagnostic System Check?	Go to Step 2	Go to Diagnostic System Check - Wiper/Washer
2	Turn ON the ignition, with the engine OFF. With a scan tool, observe the wiper delay input in the body control module (BCM) wiper/washer data list. Is the voltage greater than 4.71 volts?	Go to Step 3	Refer to Diagnostic Aids
3	Turn OFF the ignition. Disconnect the windshield wiper washer switch. Turn ON the ignition, with the engine OFF. Measure voltage between the windshield wiper switch signal circuit and the windshield wiper switch low reference circuit at the harness connector. Is the voltage less than 4 volts?	Go to Step 4	Go to Step 5
4	Measure voltage on the windshield wiper switch signal circuit to ground. Is the voltage between 4-6 volts?	Go to Step 7	Go to Step 8
5	Is voltage between 4-6 volts?	Go to Step 6	Go to Step 9
6	Using a fused jumper, jumper the windshield wiper switch signal circuit to the windshield wiper switch low reference circuit at harness connector. Is the voltage less than 0.4 volts?	Go to Step 11	Go to Step 10
7	Test the windshield wiper switch low reference circuit for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 12	Go to Step 10
8	Test the windshield wiper switch signal circuit for an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 12	Go to Step 10
9	Test the windshield wiper switch signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 12	Go to Step 10
10	IMPORTANT: Perform the programming or set up procedure for the replaced control module if required. Replace the BCM. Refer to Body Control Module Replacement in Body Control System for applicable replacement procedure.Did you complete the replacement?	Go to Step 12	-
11	Replace the windshield wiper washer switch. Refer to Multifunction, Turn Signal Switch Replacement in Steering Wheel and Column. Did you complete the replacement?	Go to Step 12	-
12	Use the scan tool to clear the DTCs. Operate the vehicle within the conditions for running the DTC as specified in the supporting text. Does the DTC reset?	Go to Step 2	System OK
