Driving Position Memory System Input Test And Function Test

WARNING: This page is about a different variant/trim than selected.

1. Connect the HDS to the data link connector (DLC) - Refer to: How to Troubleshoot the Body Electrical (2013-15), or How to Troubleshoot the Body Electrical (2016-17) .

2. Press the engine start/stop button to select the ON mode.

3. From the BODY ELECTRICAL SYSTEM SELECTION menu, select POWER SEAT/POWER MIRROR, then DTCs.

If DTCs are found, troubleshoot the DTCs using B-CAN System Diagnosis Test Mode A - Refer to: Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks (2013-15), or Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks (2016-17), .
If no DTCs are found, go to step 4 below.

4. Exit the DTC mode, and select the DATA LIST from the POWER SEAT/POWER MIRROR TEST MODE MENU

5. Test each input and monitor each output under the condition shown below:

If the data list indication is correct, continue to the next switch. If all switches are OK, go to step 7 below.
If the data list indication is not correct, do the appropriate test at the control unit and terminal indicated in the table.
- Voltage drop tests should be done with the ignition switch in ON (II) or the vehicle ignition in the ON mode, and all connectors connected and the meter negative test lead attached to a good body ground, unless specified otherwise.
- Continuity tests should be done with the ignition switch in LOCK (0) or the vehicle ignition in the OFF mode, and indicated terminals disconnected.

Data List Input/Command	Condition: Data List Indication	Control Unit/Terminal Number/Test (If applicable)	Possible cause if desired result is not obtained

6. Exit the DATA LIST and select FUNCTIONAL TESTS

7. Do each of the function tests listed in the table shown. The appropriate output should occur.

If the function operates normally, go to the next function test. If all function tests operate normally, the system is OK.
If the function does not occur, do the appropriate test at the control unit and terminal indicated in the table.
- Voltage drop tests should be done with the ignition switch in ON (II) or the vehicle ignition in the ON mode, and all connectors connected.
- Continuity tests should be done with the ignition switch in LOCK (0) or the vehicle ignition in the OFF mode, and indicated terminals disconnected.
- Jumper tests should be done according to the instructions indicated.
If the test indicates that the component operates normally, but the function will not operate by doing the function test or normal use of the component, the control unit that operates that function must be faulty; replace it.
If the test indicates that the component does not operate normally, check for an open or short in the harnesses between the component and the control unit. If the harness is OK, replace the component.
