Yes GO to S6 No REPAIR the circuit in question. - For SODCMC and SODCMD, measure:
- S6 CHECK FOR CORRECT SODCMC (SIDE OBSTACLE DETECTION CONTROL MODULE C), SODCMD (SIDE OBSTACLE DETECTION CONTROL MODULE D), SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) OR SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION
- Disconnect and inspect the SODCMC, SODCMD, SODL or SODR connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the SODCMC, SODCMD, SODL or SODR connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SODCMC, SODCMD, SODL or SODR. REFER to: Side Obstacle Detection Control Module C (SODCMC) . REFER to: Side Obstacle Detection Control Module D (SODCMD) . REFER to: Side Obstacle Detection Control Module . If the concern is still present, GO to S7 No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. - S7 CHECK FOR CORRECT IPMA (IMAGE PROCESSING MODULE A) OPERATION
- Disconnect and inspect the IPMA connectors.
