4. Measure the resistance between data link connector terminals 6 and 14.
Q: How much resistance is measured?
2 ohms or less : Diagnostic Item 9: Check the CAN_L and H lines for a short circuit.
No continuity : Diagnostic Item 11: Diagnose terminator resistors at both ends.
More than 2 ohms but continuity exists : Go to Step 3.
STEP 3. Check intermediate connector C-29 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector. For details Service Precautions/Vehicle Damage
Warnings.
Q: Is intermediate connector C-29 in good condition?
YES: Go to Step 4.
NO: Repair the damaged parts.
STEP 4. Using scan tool MB991958, diagnose the CAN bus line (Disconnect intermediate connector C-29, and then determine that a failure is
present at either the front wiring harness side or the instrument panel wiring harness side).
