1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Operate the recline adjuster switch in forward and rearward directions. Does the recline adjuster motor operate normally?	Go to Testing for Intermittent Conditions and Poor Connections	Go to Step 3
3	Install a scan tool. Observe the Recline Position Switch parameter in the seat module Inputs/Outputs data list. Operate the recline adjuster switch in the forward direction. Does the scan tool display the correct switch status parameter in relation to the actual switch position?	Go to Step 4	Go to Step 5
4	Operate the recline adjuster switch in the rearward direction. Does the scan tool display the correct switch status parameter in relation to the actual switch position?	Go to Step 7	Go to Step 6
5	Disconnect the seat adjuster switch connector. Connect a 3-amp fuse jumper wire between the battery voltage supply circuit terminal and the recline forward switch signal circuit terminal in the harness connector. Observe the Recline Position Switch parameter in the seat module Inputs/Outputs data list. Does the scan tool display the Recline Position Switch parameter as forward?	Go to Step 12	Go to Step 8
6	Disconnect the seat adjuster switch connector. Connect a 3-amp fuse jumper wire between the battery voltage supply circuit terminal and the recline rearward switch signal circuit terminal in the harness connector. Observe the Recline Position Switch parameter in the seat module Inputs/Outputs data list. Does the scan tool display the Recline Position Switch parameter as rearward?	Go to Step 12	Go to Step 9
7	Disconnect the recline adjuster motor control circuit connector. Connect a test lamp between the control circuit terminals in the harness connector. Operate the recline adjuster switch in both directions. Does the test lamp illuminate in the forward and rearward switch positions only?	Go to Step 11	Go to Step 10
8	Test the recline forward switch signal circuit for an open or short to ground. Refer to Circuit Testing and to Wiring Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 13
9	Test the recline rearward switch signal circuit for an open or short to ground. Refer to Circuit Testing and to Wiring Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 13
10	Test the recline adjuster motor control circuits for an open or short to ground. Refer to Circuit Testing and to Wiring Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 13
11	Inspect for poor connections at the recline adjuster motor. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 14
12	Inspect for poor connections at the seat adjuster switch. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 15
13	Inspect for poor connections at the seat module. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs . Did you find and correct the condition?	Go to Step 17	Go to Step 16
14	Replace the recline adjuster motor. Refer to Seat Adjuster Mechanism Replacement - Power . Is the repair complete?	Go to Step 17	-
15	Replace the seat adjuster switch. Refer to Seat Switch Replacement - Power . Is the repair complete?	Go to Step 17	-
16	Replace the seat module. Refer to Control Module References for replacement, setup and programming. Is the repair complete?	Go to Step 17	-
17	Operate the system to verify the repair. Did you correct the condition?	System OK	Go to Step 2
