3. Measure the voltage between data link connector terminal 14 and body ground.
OK: 4.0 V or less
Q: Does the voltage measure 4.0 V or less?
YES: If the voltage measures 4.0 V or less, diagnose CAN bus lines thoroughly by referring to DIAGNOSTIC ITEM 16.
NO: If the voltage measures more than 4.0 V, go to Step 30.
STEP 4. Check intermediate connector C-29 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
