Truck threw a p2138 code on me today and went into limp mode. I know the culprit is the little 9drive throttle controller, I have the OBD link mx+ and alphaobd. My question is clearing the code with the OBDlink mx +. Got nervous about clearing the ECM with it. Anybody done this? Have any tips? Do's and don'ts? Thanks.
