Then check the serial data wire C1 terminal L on the RDCLR to the BCM C1 terminal 55, Its a pink wire, make sure its ok.
checked ecm, tcm fuses ok. checked power circuit at rcdlr terminal H,ok.
checked serial data wire c1 terminal L on the rcdlr.But it is going to splice pack, not to bcm C1 terminal 55. checked continuity from rcdlr c1 terminal L to splice pack, it is ok.
