STEP 2. Measure the resistance at the BMU connector.
(1) Disconnect the BMU connector, and measure at the wiring harness side.
(2) Check the resistance between BMU connector (PRY1 terminal) and body ground.OK: Continuity exists
(3) Check the resistance between BMU connector (PRY2 terminal) and body ground.OK: Continuity exists
Is the check result normal?
Go to Step 3. Repair the connector(s) or wiring harness.
STEP 3. Using scan tool (M.U.T.-IIISE), check whether the DTC is set again.
