DTC 29 = AIR pump circuit. 9 times out of 10 it means the fuse for the AIR pump is blown. If you replace the fuse and it continues to blow, there's a good chance the pump is siezed up, or about to sieze up. You can just unplug the harness connector from the pump, and make sure there is a good fuse in the circuit, and the code and light will go away.
