Go to Symptoms

Verify the fault is present.

Does the system operate normally?

--

Go to Testing for Intermittent Conditions and Poor Connections

Go to Step 3

1. Remove the memory seat switch from door panel.
2. Using a J 39200 digital multi-meter (DMM), measure the voltage on cavity H (fused battery positive voltage) to ground.

Does the J 39200 DMM read the specified value?

11-14V

Go to Step 4

Go to Step 8

1. Turn ON the ignition, with the engine OFF.
2. With a J 39200 DMM, measure the ignition positive voltage on cavity G at inline connector C305.

Does the J 39200 DMM read the specified value?

11-14V

Go to Step 5

Go to Step 9

1. Operate the Set, the RCL 1 and the RCL 2 positions of the memory seat switch.
2. Measure the voltage at cavities E, F, and G of the memory seat switch while operating all switch selections.

Does the J 39200 DMM read the specified value?

11-14V

Go to Step 6

Go to Step 10

1. Locate the inline connector C305 at the driver seat switch.
2. With a J 39200 DMM, measure the voltage at cavities H, J, and K of connector C305 while operating all memory seat switch selections.

Does the J 39200 DMM read the specified value on the respective circuits?

11-14V

Go to Step 7

Go to Step 11

Replace the memory seat module located under the seat cushion. Refer to Memory Seat Control Module Replacement .

Go to Step 13

--

1. Repair the open in the fused battery positive voltage circuit between the memory seat switch and the mirror-lock fuse located in the fuse block. Refer to Wiring Repairs in Wiring Systems.
2. If no open is found, test for short to ground. Refer to Testing for Short to Ground in Wiring Systems.

Did you find and correct the condition?

Go to Step 13

--

1. Repair the open in the ignition positive voltage circuit between the inline connector C305 and IGN 3 fuse located in the fuse block. Refer to Wiring Repairs in Wiring Systems.
2. If no open is found, test for a short to ground. Refer to Testing for Short to Ground in Wiring Systems. Refer to Testing for Short to Ground in Wiring Systems.

Replace the memory seat switch.

Did you complete the replacement?

--

Go to Step 13

--

1. Ensure the memory seat switch is disconnected.
2. Disconnect the inline connector C305 at driver seat.
3. With a J 39200 DMM, measure the continuity at cavity H (memory seat switch signal - set), cavity J (memory seat switch signal - memory 1) and cavity K (memory seat switch signal - memory 2) between the memory seat switch and connector C305.

Is continuity present on the respective circuits?

--

Go to Step 10

Go to Step 12

Repair open or short to ground on the memory seat switch signal set circuit, the memory seat switch signal memory 1 circuit or the memory seat switch signal memory 2 circuit. Refer to Testing for Short to Ground in Wiring Systems.
