B1628/29 |
Roll Over Cut Off Indicator Malfunction |
DESCRIPTION
The RSCA off switch is a mechanism that operates both right and left side of the curtain shield airbag and the seat belt pretensioner when the center airbag sensor detects a roll-over.
The RSCA off switch indicator light is installed in the combination meter.
As operating the RSCA off switch, the indicator light comes on to inform the driver that the roll-over detection system is not working.
The initial setting of the roll-over detection system is on. It automatically operates every time the ignition switch is turned ON.

2. |
CHECK WIRE HARNESS (CENTER AIRBAG SENSOR ASSEMBLY - COMBINATION METER ASSEMBLY) |
|
(a) Turn the ignition switch to LOCK. (b) Disconnect the negative (-) terminal cable from the battery, and wait at least for 90 seconds. (c) Disconnect the center airbag sensor connector. (d) Measure the resistance between the body ground and RMSW on the C32 center airbag sensor side connector between the combination meter and center airbag sensor. Standard resistance: 1 MΩ or higher |

CHECK WIRE HARNESS (CENTER AIRBAG SENSOR ASSEMBLY - BATTERY AND BODY GROUND) |
|
(a) Disconnect the negative (-) terminal cable from the battery, and wait at least for 90 seconds. (b) Connect the combination meter connector. (c) Turn the ignition switch to LOCK, and wait at least for 90 seconds. (d) Disconnect the center airbag sensor connector. (e) Connect the negative (-) terminal cable to the battery, and wait at least for 2 seconds. (f) Turn the ignition switch to ON. (g) Measure the voltage between the body ground and IG2 on the center airbag sensor side. Standard voltage: 10 to 14 V |
|
| NG |
