Go to the next step. |
| 2 |
INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO GROUND
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module terminal.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
- Replace the malfunctioning part.
If there is no common connector:
- Replace the wiring harness which has a short to ground.
Go to Step 8. |
| No |
Go to the next step. |
| 3 |
INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR OPEN CIRCUIT
- Passenger-side air bag module and SAS control module connectors are disconnected.
- Inspect for continuity between the following terminals (wiring harness-side):
- Passenger-side air bag module terminal 1A- SAS control module terminal 3L
- Passenger-side air bag module terminal 1B-SAS control module terminal 3M
NOTE:
- Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is there continuity?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module terminal.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
- Replace the malfunctioning part.
If there is no common connector:
- Replace the wiring harness which has an open circuit.
Go to Step 8. |
| 4 |
INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO POWER SUPPLY
- Passenger-side air bag module and SAS control module connectors are disconnected.
- Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION
.)
- Switch the ignition ON (engine off or on).
- Measure the voltage at the following terminals (wiring harness-side):
- SAS control module terminal 3L
- SAS control module terminal 3M
NOTE:
- Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is the voltage 0 V?
|
Yes |
Go to the next step. |
| No |
Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module terminal.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
- Replace the malfunctioning part.
If there is no common connector:
- Replace the wiring harness which has a short to power supply.
Go to Step 8. |
| 5 |
INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO EACH OTHER
- Passenger-side air bag module and SAS control module connectors are disconnected.
- Switch the ignition off.
- Inspect for continuity between the following terminals (wiring harness-side):
- Passenger-side air bag module terminal 1A-SAS control module terminal 3M
- Passenger-side air bag module terminal 1B-SAS control module terminal 3L
NOTE:
- Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module terminal.
If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to each other.
- Replace the malfunctioning part.
If there is no common connector:
- Replace the wiring harness which has a short to each other.
Go to Step 8. |
| No |
Go to the next step. |
| 6 |
INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO OTHER AIR BAG MODULE CIRCUIT
- Passenger-side air bag module and SAS control module connectors are disconnected.
- Other air bag module and pre-tensioner seat belt connectors are disconnected.
- Refer to the wiring diagram and inspect for continuity between the passenger-side air bag module terminals and other air bag module/pre-tensioner seat belt terminals (wiring harness-side).
NOTE:
- Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
- Is there continuity?
|
Yes |
Refer to the wiring diagram and verify whether or not there is a common connector between passenger-side air bag module terminal and other air bag module/pre-tensioner seat belt terminal. If there is a common connector:
- Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to other air bag module or pre-tensioner seat belt circuit.
- Replace the malfunctioning part.
If there is no common connector:
- Replace the wiring harness which has a short to other air bag module or pre-tensioner seat belt circuit.
Go to Step 8. |
| No |
