FOOT-MOTION DETECTION UNIT INSPECTION

id091100809200

1.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Remove the foot-motion detection unit. (SeeFOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION.)

3.  Reconnect the foot-motion detection unit connectors.

4.  Connect the negative battery terminal.

5.  Verify that the voltages of each of the terminals are as indicated in the Terminal Voltage Table (Reference).

•  If the voltage is not as indicated in the table, inspect the parts under Inspection item(s).
?  If the system does not launch normally even though inspection items are normal, specify the location of the malfunction based on the instructions from the on-board diagnostic system and the symptom troubleshooting, and perform repairs.
