Control Unit Input Test

Control Unit Input Test





Disconnect the 7-P and 22-P connectors from the control unit, located under the right front seat.





Make the illustrated input tests at the harness pins.

NOTE:
^ Recheck the connections between the 7-P, 22-P connectors and control unit; then replace the control unit if all input tests prove OK.
^ Several different wires have the same color. They have been given a number suffix to distinguish them (for example WHTIGRN1 and WHT/GRN2 are not the same).





With ignition switch ON, connect the 7-P and 22-P connectors to the control unit and perform tests 10-16.
