Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Input Tests: Notes
Remove the left kick panel, then disconnect the 12-P connector from the integrated control unit. Remove the integrated control unit from the under-dash fuse/relay box. Inspect the connector and socket terminals to be sure they are all making good contact. See Fig 1 .
Make the following input tests at the HARNESS pins. If all tests prove OK, yet the system still fails to work, replace the control unit.
