Main code 69 indicates the ECU has malfunctioned. ECU, open driver, C solenoid circuit To assist in tracking ECU reliability, the subcode has been included to indicate the cause of the ECU malfunction. Most codes, except Code 69 34, can be cleared; but they will probably recur. Replacing the ECU corrects the problem.
