SASM DTC Chart

DTC	Description	Action
C1B00:49	Steering Angle Sensor: Internal Electrical Failure	CHECK vehicle service history for recent service actions related to the SASM . This DTC will set due to incomplete or improper flash programming procedures. If there have been recent service actions with the SASM , REPEAT the programming procedure as directed by the diagnostic scan tool. If there have been no recent service actions, CLEAR the DTC , CYCLE the ignition, CARRY OUT the SASM self-test. If the DTC returns, INSTALL a new SASM to correct the failure to retain software data. REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:61	Steering Angle Sensor: Signal Calculation Failure	This DTC indicates that part of the SASM has failed internally. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:62	Steering Angle Sensor: Signal Compare Failure	This DTC indicates that part of the SASM has failed internally. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:64	Steering Angle Sensor: Signal Plausibility Failure	CLEAR the DTC . TEST DRIVE the vehicle and CARRY OUT at least 1 left turn and 1 right turn. CARRY OUT a SASM self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:81	Steering Angle Sensor: Invalid Serial Data Received	This DTC indicates that part of the SASM has failed internally. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:85	Steering Angle Sensor: Signal Above Allowable Range	SET the front wheels to the straight ahead position. Using a diagnostic scan tool, OBSERVE the SASM steering wheel angle (SW_ANGLE) Parameter Identification (PID). If the Parameter Identification (PID) displays 0 degrees, CLEAR the DTC , REPEAT the SASM self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) . If the Parameter Identification (PID) displays more than 0 degrees, SET the ignition to OFF. REMOVE the SASM , REFER to: STEERING ANGLE SENSOR MODULE (SASM) . Leave the electrical connector connected. SET the ignition to ON (this sets Diagnostic Trouble Codes (DTCs) in multiple modules). Manually ADJUST the SASM until the SW_ANGLE Parameter Identification (PID) displays 0 degrees. SET the ignition to OFF. INSTALL the SASM . CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs) in all modules.
C1B00:87	Steering Angle Sensor: Missing Message	The SASM sets this DTC when the module transmits information on the High Speed Controller Area Network (HS-CAN) but does not get a response from any other module. REFER to: COMMUNICATIONS NETWORK .
C1B00:92	Steering Angle Sensor: Performance or Incorrect Operation	CLEAR the DTC . TEST DRIVE the vehicle and CARRY OUT at least 1 left turn and 1 right turn. CARRY OUT a SASM self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
C1B00:96	Steering Angle Sensor: Component Internal Failure	This DTC indicates that part of the SASM has failed internally. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If the DTC returns, INSTALL a new SASM . REFER to: STEERING ANGLE SENSOR MODULE (SASM) .
U0001:88	High Speed CAN Communication: Bus Off	The module could not communicate on the network at a point in time. The fault is not currently present since the module had to communicate with the diagnostic scan tool to report this DTC . VERIFY the integrity of the connectors and wiring. Refer to MODULE COMMUNICATIONS NETWORK for schematic and connector information.
U0140:00	Lost Communication With Body Control Module: No Sub Type Information	GO to PINPOINT TEST D
U0300:00	Internal Control Module Software Incompatibility: No Sub Type Information	GO to PINPOINT TEST R
U3003:62	Battery Voltage: Signal Compare Failure	GO to PINPOINT TEST L
