Dodge Nitro. Manual — part 181

Continuously, with ignition on, until vehicle speed exceeds 20 km/h (12.4 m.p.h.) for the first time, but
not if the sensor voltage is out of range.

Or, during diagnostic mode.

Or, if the monitoring was inhibited by a corresponding diagnostics command.

Set Condition:

If the measured acceleration signal is higher than 0.8 g for longer than the specified detection time.

Diagnostic Test

1) CHECK FOR A DTC C1210-G SENSOR INPUT CIRCUIT PERFORMANCE

Turn the ignition on.

With the scan tool, read and record DTCs.

With the scan tool, read and record Freeze Frame information.

With the scan tool, erase DTCs.

Cycle the ignition switch from off to on.

With the scan tool, read and record DTCs.

Does the scan tool display: C1210-G SENSOR INPUT CIRCUIT PERFORMANCE?

Yes

Go to 2).

No

Possible Causes
