Troubleshooting Diagnostic Procedure

B00C2-93: (SAS) TROUBLESHOOTING DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	PURPOSE: INSPECT FOR MALFUNCTION IN WIRING HARNESS (INCLUDING CONNECTOR/TERMINAL) BETWEEN SEAT WEIGHT SENSOR (RF) AND SEAT WEIGHT SENSOR CONTROL MODULE Switch the ignition/main power OFF. Disconnect the negative battery terminal/negative lead-acid battery terminal and wait for 1 min or more. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION in service information.) Inspect the applicable circuit. (See CIRCUIT INSPECTION .) (See CONNECTOR INSPECTION .) NOTE: Inspect the circuit while shaking the wiring harness between the seat weight sensor (RF) and the seat weight sensor control module. Is the circuit normal?	Yes	Replace the seat weight sensor (RF), then go to the next step. (Refer to SEAT WEIGHT SENSOR REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA/ISRAEL SPEC.] in service information.)
1		No	Repair or replace the malfunctioning location and perform repair completion verification 1.
2	PURPOSE: INSPECT SEAT WEIGHT SENSOR CONTROL MODULE FOR MALFUNCTION DEPENDING ON REPEATABILITY Switch the ignition/main power OFF. Disconnect the negative battery terminal/negative lead-acid battery terminal and wait for 1 min or more. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION in service information.) Install/connect the part removed/disconnected during the troubleshooting procedure. Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the DTC inspection for the SAS control module. (See DTC INSPECTION .) Is the same DTC displayed?	Yes	Refer to the CAN (controller area network) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, replace the seat weight sensor control module and perform repair completion verification1. (Refer to SEAT WEIGHT SENSOR CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA/ISRAEL SPEC.] in service information.)
2		No	Perform repair completion verification 2.
Repair completion verification 1	PURPOSE: VERIFY IF VEHICLE IS REPAIRED Clear the DTC recorded in the memory. (See CLEARING DTC .) Perform the DTC inspection for the SAS control module. (See DTC INSPECTION .) Is the same DTC displayed?	Yes	Refer to the CAN (controller area network) malfunction diagnosis flow to inspect for a CAN communication error. (See MALFUNCTION DIAGNOSIS FLOW [CONTROLLER AREA NETWORK (CAN)] .) If the CAN communication is normal, perform the diagnosis from Step 1 again. If the malfunction is not resolved, replace the SAS control module, then go to the next step. (Refer to SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA/ISRAEL SPEC.] in service information.)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs ARE DISPLAYED Perform the DTC INSPECTION. (See DTC INSPECTION .) Are other DTCs displayed?	Yes	Repair or replace the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
