Signal Missing

Signal missing. Intermittent fault

Checking wiring and terminals
- Disconnect the connectors for the control module for the steering wheel angle sensor and the steering wheel module (SWM)
- Connect the breakout box.
Check the cable between the control module for the steering wheel angle sensor terminal #7 (#A31) and steering wheel module (SWM) terminal #14 (#A14). Check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Check the wiring between the control module for the steering wheel angle sensor:
terminal #9 (terminal (#A33) and steering wheel module (SWM) terminal #12 (terminal #A12)
terminal #8 (terminal (#A32) and steering wheel module (SWM) terminal #7 (terminal #A7)
check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).

Do you want to view the information again?

Yes - Attempt New Test

No - Exit fault-tracing
