Believe that with the new battery has solved the issue for a while. However the error message trans failsafe came back after 1~2 hours later. Did the OBC test 9 last night, it shows 12.2V when switch is in ON position. Start the engine, it shows 13.8V without load. It was then dropped to 13.4V with aircon, headlight (HID), Door lights, Foglight ON. The trans failsafe message still there. Is the voltage reading above show normal? Thanks</p></blockquote><p></p>
