replace the ODS unit harness, then clear the DTC.
10. Measure the resistance between ODS unit harness 18P connector terminals No. 4 and No. 14. There
should be an open circuit or at least 1 M .
Faulty ODS unit; replace the ODS unit
(see page 24-209), then clear the DTC.
Short in the ODS unit harness; replace the
ODS unit harness, then clear the DTC. 11. Turn the ignition switch to LOCK (0).
12. Swap the connections between the front
passenger’s weight sensor (rear inner side) and the
