DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition CCM B142E:78 Forward Looking Sensor Horizontal Alignment: Alignment Or Adjustment Incorrect Set by the CCM as a continuous memory and on-demand DTC if the CCM detects a misalignment of the radar due to the horizontal alignment angle being out of range. CCM B1432:78 Forward Looking Sensor Vertical Alignment: Alignment Or Adjustment Incorrect Set by the CCM as a continuous memory and on-demand DTC if the CCM detects a misalignment of the radar due to the vertical alignment angle being out of range. CCM B1433:54 Forward Looking Sensor Alignment: Missing Calibration Set by the CCM as a continuous memory and on-demand DTC if the CCM detects a misalignment of the radar due to the alignment angle being out of range. Possible Sources
- CCM alignment
- CCM bracket
- CCM
- NOTE: The CCM radar vertical and horizontal alignment procedure is located in General Procedures. The horizontal alignment for the CCM is a calibration check performed by the scan tool to insure the CCM radar is pointed straight. The scan tool identifies this as, Alignment Offset (
Access the CCM and monitor the ALGN_OFF (Deg) PID
NOTE: ) with a horizontal specification of +/- 3.0 degrees offset. - C1 INSPECT THE CCM (CRUISE CONTROL MODULE) BRACKET
- Remove the front bumper cover. Refer to: Cruise Control Module (CCM) .
- Inspect for damage to the CCM bracket and radar attachments to the bracket.
Is the CCM bracket or radar attachments to the bracket damaged?
Yes INSTALL a new CCM bracket or radar attachments, as necessary. Refer to: Cruise Control Module (CCM) . No GO to C2 - C2 PERFORM THE VERTICAL AND HORIZONTAL ALIGNMENT
- Perform the alignment procedures for the CCM. Refer to: Cruise Control Radar Alignment .
Does the CCM align correctly?
Yes The system is operating correctly at this time. The concern was caused by a misaligned sensor. No INSTALL a new CCM. Refer to: Cruise Control Module (CCM) .
