Power Windows Inoperative - Express Up Function

Step	Action	Value(s)	Yes	No
Schematic Reference: Power Window Schematics (w/o WC2/WC8) or Power Window Schematics (w/WC2/WC8) DEFINITION: This test is used when only the Express Up function of a window is inoperative. This test assumes that all DTCs have been diagnosed.
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Verify that the Power Windows Inoperative - Express Up Function complaint is present. Does the power windows express up system operate as described in the Description and Operation?	-	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 3
3	Install a scan tool. Turn ON the ignition, with the engine OFF. With the scan tool, observe the appropriate Window Switch parameter in the Driver Door Switch, Inputs list. Using the appropriate window switch on the driver door switch assembly (DDSA), attempt to operate the inoperative window to the Express Up position. Did the parameter change from the Idle state to the Express Up state?	-	Go to Step 4	Go to Step 10
4	Is the window that does not operate in the Express Up mode the passenger front door window?	-	Go to Step 5	Go to Step 6
5	With the scan tool, observe the Window Switch Inputs parameter in the Passenger Door Module, Inputs list. Operate the passenger front door window switch to the Express Up position. Did the parameter change from the Idle state to the Express Up state?	-	Go to Step 6	Go to Step 12
6	Disconnect the harness connector of the appropriate window sensor/motor assembly. Measure the voltage from the power window high speed serial data circuit of the harness connector to a good ground. Does the voltage measure within the specified value?	5.0-9.0 V	Go to Step 11	Go to Step 7
7	Test the power window high speed serial data circuit for a short to ground, 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 17	Go to Step 8
8	Test the power window high speed serial data circuit for a short to battery positive voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 9
9	Inspect for poor connections at the harness connector of the appropriate door module. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 13
10	Inspect for poor connections at the harness connector of the DDSA. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 14
11	Inspect for poor connections at the harness connector of the appropriate window sensor/motor assembly. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 15
12	Inspect for poor connections at the harness connector of the inoperative passenger door window switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 16
13	Replace the inoperative door module. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 17	-
14	Replace the inoperative DDSA. Refer to Front Door Switch Replacement . Did you complete the replacement?	-	Go to Step 17	-
15	Replace the inoperative window sensor/motor assembly. Refer to Window Regulator Replacement - Front Door . Did you complete the replacement?	-	Go to Step 17	-
16	Replace the inoperative passenger front door window switch. Refer to Front Door Switch Replacement . Did you complete the replacement?	-	Go to Step 17	-
17	Re-initialize the window sensor/motor. Refer to Window Motor Programming - Express Function . Operate the system in order to verify the repair. Did you correct the condition?	-	System OK	Go to Step 2
