- If the original configuration does not match the actual vehicle equipment, reprogram the SDM with the correct configuration.
- Ignition OFF, disconnect the harness connectors at the SDM and verify the connector is in good condition and has no bent pins, terminals or shorting bars
- If damage is found, repair the bent pins, terminals or shorting bars as needed and perform the Setup New SDM procedure.
