If this code continues after all repairs have been made — or if you receive a code for a
component that is not installed on the vehicle — it may be necessary to reconfigure the ECU.
Refer to Appendix III. TOOLBOX™ Software may also be used to reconfigure the ECU (refer to
Appendix III). Contact ArvinMeritor’s Customer Service Center at 800-535-5560 for
reconfiguration information.
