OPU Problem Inspection Procedure |

TEST OPU GROUND CIRCUIT: Measure resistance between OPU and chassis
ground using the backside of OPU harness connector as OPU side check
point. If the problem is found, repair it.

TEST OPU CONNECTOR: Disconnect the OPU connector and visually
check the ground terminals on OPU side and harness side for bent pins
or poor contact pressure. If the problem is found, repair it.

If so, make sure there were no DTC's before swapping the OPU with a
new one, and then check the vehicle again. If DTC's were found, examine
this first before swapping OPU.
