Diagnostic Procedure

Step

Inspection

Results

Action
1
VERIFY BCM DTCs
•  Perform the DTC inspection for the BCM using the M-MDS.
•  Is a DTC detected?
Yes
Perform the applicable DTC troubleshooting.
(See DTC TABLE [BODY CONTROL MODULE (BCM) (E)].)
No
Go to the next step.
2
INSPECT INDICATOR UNIT CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the negative battery terminal.
•  Disconnect the indicator unit connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is there any malfunction of the indicator unit connector?
Yes
Replace the malfunctioning part and perform the repair completion verification.
No
Go to the next step.
3
INSPECT BCM CONNECTOR CONDITION
•  Disconnect the BCM connector.
•  Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.
•  Is the connector normal?
Yes
Go to the next step.
No
Replace the malfunctioning part and perform the repair completion verification.
4
INSPECT SEAT PAD OFF INDICATOR CIRCUIT FOR SHORT TO GROUND
•  Indicator unit and BCM connectors are disconnected.
•  Inspect the PAD OFF indicator circuit for short to ground.
Note
•  Inspect for a short to ground while shaking the wiring harness between the indicator unit and BCM.
•  Is the circuit normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
5
INSPECT PAD OFF INDICATOR CIRCUIT FOR OPEN CIRCUIT
•  Indicator unit and BCM connectors are disconnected.
•  Inspect the PAD OFF indicator circuit for open circuit.
Note
•  Inspect for open circuit while shaking the wiring harness between the indicator unit and BCM.
•  Is the circuit normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
6
INSPECT PAD OFF INDICATOR CIRCUIT FOR SHORT TO POWER SUPPLY
•  Indicator unit and BCM connectors are disconnected.
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off or on).
•  Inspect the PAD OFF indicator circuit for a short to power supply.
Note
•  Inspect for a short to power supply while shaking the wiring harness between the indicator unit and BCM.
•  Is the circuit normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
7
INSPECT INDICATOR UNIT
•  Inspect the indicator unit.
•  Is it normal?
Yes
Perform the repair completion verification.
No
Replace the indicator unit and perform the repair completion verification.
(See INDICATOR UNIT REMOVAL/INSTALLATION.)
Repair completion verification
PERFORM SAS CONTROL MODULE DTC INSPECTION
•  Reconnect all disconnected connectors.
•  Connect the negative battery terminal.
•  Switch the ignition ON (engine off or on).
•  Clear the DTC for the SAS control module using the M-MDS.
•  Perform the DTC inspection for the SAS control module using the M-MDS.
•  Are the same Pending DTCs present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)
If the CAN communication is normal, perform the diagnosis from Step 1.
•  If the malfunction recurs, replace the SAS control module.
No
DTC troubleshooting completed.
