System Input Test and Function Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect the HDS to the data link connector.
  2. Turn the ignition switch to ON (II).
  3. From the BODY ELECTRICAL SYSTEM SELECT menu, select POWER SEAT/POWER MIRROR, then DTCs.
  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 under the condition shown below:
    • If the data list indication is correct, continue to the next switch. If all switches are OK, go to next step.
    • 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) 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) and indicated terminals disconnected.

  6. Exit the DATA LIST and select FUNCTION TEST.
  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) and all connectors connected.
      • Continuity tests should be done with the ignition switch in LOCK (0) 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. 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 harnesses between the component and the control unit. If the harness is OK, replace the component.
