Diagnostic Trouble Code (DTC) Information SRS-0218

Condition 

Fig 1: Identifying Front Right Front Impact Sensor

Courtesy of VOLVO CARS CORPORATION

The Supplemental Restraint System Module (SRS) checks the signal from the front left front impact sensor.

Diagnostic trouble code (DTC) SRS-0218 is stored if the control module registers an incorrect signal, i. e. that the signal in the signal cable is too low or too high for longer than 10 seconds.

Diagnostic trouble code (DTC) SRS-0218 can be diagnosed in ignition positions I, II or III.

Substitute Value 

• None.

Possible Source 

• Short-circuit to supply voltage in the signal cable between the front left front impact sensor and the Supplemental Restraint System Module (SRS)
• Short-circuit to ground in the signal cable between the front impact sensor and the Supplemental Restraint System Module (SRS)
• Short-circuit to supply voltage in the connector
• Short-circuit to ground in the connector
• Short-circuit between signal cables to the front impact sensor from the Supplemental Restraint System Module (SRS)
• Short-circuit in the front impact sensor (defective front impact sensor).

Fault symptom[s] 

• The SRS indicator lamp is lit.
