B1D35:11 Hazard switch: short to ground Continuous memory and on-demand DTC that is set when the BCM detects a short to ground in the hazard warning function input circuit.
U1000:00 Solid State Driver Protection Active - Driver Disabled: No Subtype Information This DTC sets when the BCM has temporarily disabled an output driver. The module has temporarily disabled the output due to excessive current draw (for example, a short to ground). The BCM cannot turn the output on until the cause of the short is repaired. The DTCs have been cleared and a self-test is initiated.
U3000:49 Control Module: Internal Electronic Failure This DTC sets when the BCM has permanently disabled an output driver. The module has permanently disabled the output because excessive current draw (for example, a short to ground) exceeded the limits the BCM can withstand. REPAIR the cause of the excessive current draw before installing a new BCM.
