For a complete wiring diagram Refer to Section 8W.When Monitored:With the ignition on, the Front Left Impact Sensor is equipped with on board diagnostics to monitor to sensor's internal circuits. If a problem is identified, the sensor sends the Front Left Impact Sensor Internal message to the Occupant Restraint Controller (ORC).Set Condition:This DTC will set if the ORC receives an internal DTC from the Front Left Impact Sensor.Possible Causes FRONT LEFT IMPACT SENSOROCCUPANT RESTRAINT CONTROLLER (ORC)1. DETERMINE ACTIVE OR STORED FAULT CODEEnsure the battery is fully charged.Turn the ignition on.Wait one minute, and read active codes.Is the DTC: B1B70-UP-FRONT LEFT SATELLITE ACCELERATION SENSOR INTERNAL active? YesGo To 2 NoGo To 42. VERIFY OPERATION OF THE FRONT LEFT IMPACT SENSORTo avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Replace the Front Left Impact Sensor.Reconnect the vehicle wire harness to the sensor.Remove any special tools or jumper wires and reconnect all previously disconnected components - except the Battery.To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.Use the scan tool and erase the stored codes in all airbag system modules.Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.Wait one minute, and read active codes.Did the active DTC: B1B70-UP-FRONT LEFT SATELLITE ACCELERATION SENSOR INTERNAL return?YesGo To 3NoRepair is complete.Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.3. REPLACE THE OCCUPANT RESTRAINT CONTROLLERTo avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.If the Occupant Restraint Controller (ORC) is dropped at any time, it must be replaced. Failure to take the proper precautions can result in accidental airbag deployment and serious or fatal injury.If there are no possible causes remaining, view repair.RepairReplace the ORC in accordance with Service Instructions.Perform the *AIRBAG SYSTEM VERIFICATION TEST - VER 1.4. TEST FOR AN INTERMITTENT CONDITIONWith the scan tool, record and erase all DTC from all Airbag modules.If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.To avoid serious or fatal injury, turn the ignition off, disconnect the battery and wait two minutes before proceeding.Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.The following additional checks may assist you in identifying a possible intermittent problem.Reconnect any disconnected components and harness connector.To avoid serious or fatal injury, turn the ignition on, then reconnect the battery.With the scan tool, monitor active codes as you work through the following steps.To avoid serious or fatal injury, maintain a safe distance from all airbags while performing the following steps.Wiggle the wiring harness and connectors of the related airbag circuit or component.If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.If only stored codes return continue the test until the problem area has been isolated.In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.Are any ACTIVE DTC present?YesSelect appropriate symptom from Symptom List.NoNo problem found at this time. Erase all codes before returning vehicle to customer.
