The technician may observe one or more of the following diagnostic trouble codes stored in the memory: POA2D POA33 POA3F POA40 P1B03 POA2C Cause: A potential cause for the above conditions is a poor connection on connector X176 (the 24 pin transmission connector). Correction: Inspect the connection, paying careful attention to terminals 12 and 13 as there have been cases where these connectors have backed out of the plug. Also inspect the wiring harness for chaffing as this too has been observed to cause similar conditions.
