| Step |
Inspection |
Results |
Action |
| 1 |
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) CONNECTOR
|
Yes |
Replace the malfunctioning part and perform the repair completion verification. |
| No |
Go to the next step. |
| 2 |
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) DEPLOYMENT SIGNAL CIRCUIT FOR SHORT TO GROUND
|
Yes |
Go to the next step. |
| No |
Repair or replace the malfunctioning location and perform the repair completion verification. |
| 3 |
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) DEPLOYMENT SIGNAL CIRCUIT FOR OPEN CIRCUIT
- Passenger-side air bag module (inflator No. 1) and SAS control module connectors are disconnected.
- Inspect the passenger-side air bag module (inflator No. 1) deployment signal circuit for open circuit. (See CIRCUIT INSPECTION
.)
NOTE:
- Inspect for open circuit while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is the circuit normal?
|
Yes |
Go to the next step. |
| No |
Repair or replace the malfunctioning location and perform the repair completion verification. |
| 4 |
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) DEPLOYMENT SIGNAL CIRCUIT FOR SHORT TO EACH OTHER
- Passenger-side air bag module (inflator No. 1) and SAS control module connectors are disconnected.
- Inspect the passenger-side air bag module (inflator No. 1) deployment signal circuit for short to each other. (See CIRCUIT INSPECTION
.)
NOTE:
- Inspect for short to each other while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- 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 PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) DEPLOYMENT SIGNAL CIRCUIT FOR SHORT TO OTHER AIR BAG MODULE CIRCUIT
- Passenger-side air bag module (inflator No. 1) and SAS control module connectors are disconnected.
- Other air bag module and pretensioner seat belt connectors are disconnected.
- Refer to the wiring diagram and inspect for continuity between the following terminals and other air bag module/pre-tensioner seat belt terminals (wiring harness-side).
- SAS control module terminal 1AD
- SAS control module terminal 1AH
NOTE:
- Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is there continuity?
|
Yes |
Repair or replace the malfunctioning location and perform the repair completion verification. |
| No |
Go to the next step. |
| 6 |
INSPECT PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1) DEPLOYMENT SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY
- Passenger-side air bag module (inflator No. 1) and SAS control module connectors are disconnected.
- Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US)
.)
- Switch the ignition ON (engine off or on).
- Inspect the passenger-side air bag module (inflator No. 1) deployment signal circuit for a short to power supply. (See CIRCUIT INSPECTION
.)
NOTE:
- Inspect for a short to power supply while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- 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 PASSENGER-SIDE AIR BAG MODULE (INFLATOR No. 1)
- Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US)
.)
- Connect the SAS control module connectors.
- Except for the passenger-side air bag module (inflator No. 1) connector, reconnect all disconnected connectors.
- Apply 2 ohms resistance to the passenger-side air bag module (inflator No. 1) terminals 1A and 1B (wiring harness-side).
- Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION (US)
.)
- Switch the ignition ON (engine off or on).
- Clear the DTC for the SAS control module using the M-MDS. (See CLEARING DTC
.)
- Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION
.)
- Are the same Pending DTCs present?
|
Yes |
Perform the repair completion verification. |
| No |
Replace the passenger-side air bag module and perform the repair completion verification. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM - US/CANADA SPEC.]
.) |
| Repair completion verification |
PERFORM SAS CONTROL MODULE DTC INSPECTION
|
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 (US)
.) If the CAN communication is normal, perform the diagnosis from Step 1.
