Diagnosis ProcedureINFOID:0000000009461505
1.CHECK HARNESS CONTINUITY (OPEN CIRCUIT)
1. Turn the ignition switch OFF.
2. Disconnect the battery cabl e from the negative terminal.
3. Disconnect the following harness connectors.
- Combination meter
-BCM
4. Check the continuity between the combination meter harness connector and the BCM harness connector.
Is the inspection result normal?
YES (Present error)>>Check CA N system type decision again.
YES (Past error)>>Error was detected in the main line between the combination meter and the air bag diag-
nosis sensor unit.
NO >> Repair the main line between the combination meter and the air bag diagnosis sensor unit.

1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cabl e from the negative terminal.
3. Check the terminals and connectors of the steer ing angle sensor for damage, bend and loose connection
(unit side and connector side).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair the terminal and connector.
2.CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of steering angle sensor.
2. Check the resistance between the steering angle sensor harness connector terminals.
Is the measurement value within the specification?
YES >> GO TO 3.
NO >> Repair the steering angle sensor branch line.
3.CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the steering angle sensor. Refer to BRC-47, "Wiring Dia-
gram".
Is the inspection result normal?
YES (Present error)>>Replace the steering angle sensor. Refer to BRC-132, "Removal and Installation".
YES (Past error)>>Error was detected in the steering angle sensor branch line.
NO >> Repair the power supply and the ground circuit.

nection (unit side and connector side).
Is the inspection result normal?
YES >> GO TO 2.
NO >> Replace the main harness.
2.CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Check the air bag diagnosis sensor unit. Refer to SRC-40, "Work Flow"
.
Is the inspection result normal?
YES >> Replace the main harness.
NO >> Replace parts whose air bag system has a malfunction.
