B0022 CADILLAC Possible Causes
- Faulty clockspring coil
- Clockspring coil wiring harness is open or shorted
- Poor electrical connection in the clockspring coil circuit
- Faulty clockspring
How to Fix B0022 CADILLAC Code?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
Possible Symptoms
- Airbag warning light illuminated
B0022 CADILLAC Meaning
The driver deployment loop consists of the following:
– A dual-stage inflatable restraint steering wheel module
– The steering wheel inflatable restraint module coil
– The high circuits of the steering wheel module for both stage 1 and 2
– The low circuits of the steering wheel module for both stage 1 and 2
There are 2 shorting bars used in the steering wheel module coil connector. These shorting bars short together both stages of the steering wheel module high circuit and the steering wheel module low circuit when the connector is disconnected. This helps prevent unwanted deployment of the inflator module during service. During a frontal collision of sufficient force, the Sensing and Diagnostic Module (SDM) will allow current to flow through the deployment loop. This current flow will deploy the steering wheel module. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and shorts to ground or voltage. If a malfunction is detected, a DTC will be stored in memory.
