OPU Problem Inspection Procedure |
1. |
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.
|
2. |
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.

3. |
If problem is not found in Step 1 and 2, the OPU could be faulty.
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.

RE-TEST THE ORIGINAL OPU: Install the original OPU (may be broken)
into a known-good vehicle and check the vehicle. If the problem occurs
again, replace the original OPU with a new one. If problem does not
occur, this is intermittent problem (Refer to “Intermittent Problem
Inspection Procedure” in Basic Inspection Procedure
