Airbag Circuit
CAUTION:
- Do not rotate the steering roll connector to more than the specified number of turns. Otherwise, the roll connector internal wire may be broken.
- When determining the end stop, rotate the connector slowly without applying excessive force. Applying excessive force at the end stop may break the internal wire.
- Adjust the steering roll connector. Ref. to AIRBAG SYSTEM>ROLL CONNECTOR>ADJUSTMENT .
- Set the steering roll connector to the central position.
- Connect ST1 to connector B.
Preparation tool:
ST1: TEST HARNESS N (98299SA000)
ST2: TEST HARNESS Q (98299SA040)
- Connector - ST1 (1N)
- Connector C - ST2 (1Q)
- With the following conditions, check the resistance between the connector terminals of ST1 and ST2.
- Perform the check with the steering roll connector centered (front wheels direct straightforward).
- Rotate the steering roll connector counterclockwise from the center (front wheels direct straightforward) to an end stop.
Then, perform the check while rotating it clockwise to approximately 4.5 turns.
NOTE:- The illustration shows the model with steering heater.
- The connector A is designed to short the terminals A1/A2 and A3/A4 when disconnected.
Terminal No. Inspection conditions Standard (2N) No. 1 - (2N) No. 2 Always Less than 1 Ω (2Q) No. 1 - (2Q) No. 2 Always Less than 1 Ω - Replace the steering roll connector if the inspection result is not within the standard value.
