System Input Test and Function Test

System Input Test and Function Test

NOTE: Make sure you have the latest software on the HDS before troubleshooting.

1. Connect the HDS to the DLC.
2. Turn the ignition switch ON (II).
3. From the BODY ELECTRICAL SYSTEM SELECT menu, select POWER SEAT/POWER MIRROR, then DTCs.
- If DTCs are found, troubleshoot the DTCs using B-CAN System Diagnostic Test Mode A.
- If no DTCs are found, go to step 4.

4. Exit the DTC mode and select DATA LIST from the POWER SEAT/POWER MIRROR TEST MODE menu.
5. Test each input and monitor each output on the data list under the condition listed below.
- If the data list indication is correct, continue to the next switch. If all switches are OK, go to step 6.
- If the data list indication is not correct, perform the appropriate test at the control unit and terminal indicated in the table.
- Voltage drop tests should be performed with the ignition switch ON (II) and all connectors connected and the meter negative test lead attached to a good body ground or the battery negative post.
- Continuity tests should be performed with the ignition switch OFF and the indicated terminals disconnected.
- Check terminal fit and ground G601 before doing any test.












6. Exit the DATA LIST and select Function Test.
7. Perform each of the function tests listed in the table below. 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 operate normally, perform the appropriate test at the control unit and terminal indicated in the table.
- Voltage drop tests should be performed with the ignition switch ON (II) and all connectors connected
- Continuity tests should be performed with the ignition switch OFF and the 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 does not operate with the function test or the 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 harness between the component and the control unit. If the harness is OK, replace the component.
