The park assist sensors (Fig. 1) for Front and Rear Park Assist Systems (RPO UD7, UD5, UFQ, UKG, UKZ) on some 2018-2022 GM passenger cars, crossovers, trucks and SUVs may be damaged due to a number of conditions. Park assist sensors with non-warrantable damage or conditions, such as visible impact damage, should not be replaced under warranty.<\/p>\n

 <\/p>\n

 <\/p>\n

Here are some examples of non-warrantable damage or conditions to park assist sensors.<\/p>\n

 <\/p>\n

Stone Chip and Membrane Damage<\/strong><\/p>\n

Check for a sensor with visible stone chip and membrane damage. (Fig. 2)<\/p>\n

 <\/p>\n

 <\/p>\n

Damaged Connector<\/strong><\/p>\n

Inspect the sensor for damage to the connector. (Fig. 3)<\/p>\n

 <\/p>\n

\"\"Fig. 3<\/strong><\/p>\n

 <\/p>\n

Damaged Retained Tabs<\/strong><\/p>\n

The retaining tabs should not show any damage from impacts or improper removal. (Fig. 4)<\/p>\n

 <\/p>\n

\"\"Fig. 4<\/strong><\/p>\n

 <\/p>\n

Twisted Sensors<\/strong><\/p>\n

The double marks on the sensor should be aligned. (Fig. 5) Do not twist the sensor to try and remove the painted cap.<\/p>\n

 <\/p>\n

\"\"Fig. 5<\/strong><\/p>\n

 <\/p>\n

A twisted sensor without the marks aligned is typically caused during sensor removal or installation. (Fig. 6)<\/p>\n

 <\/p>\n

\"\"Fig. 6<\/strong><\/p>\n

 <\/p>\n

Painted Incorrectly<\/strong><\/p>\n

Verify the sensor is painted correctly without any overspray, grinding or re-painting. (Fig. 7) Follow the appropriate Service Information for the correct painting procedure. Do not refinish previously painted sensors. Excess paint build-up will cause the sensor to be inoperative.<\/p>\n

 <\/p>\n

\"\"Fig. 7<\/strong><\/p>\n

 <\/p>\n

Connector Interface<\/strong><\/p>\n

Check for any damage by the outside environment, including a corroded connector. (Fig. 8)<\/p>\n

 <\/p>\n

\"\"Fig. 8<\/strong><\/p>\n

 <\/p>\n

Be sure to precisely follow the removal and installation procedures in the appropriate Service Information in order to avoid sensor damage.<\/p>\n

Refer to Bulletin #22-NA-012 for additional information.<\/p>\n
