Dodge Nitro. Manual — part 692

Is actuated with a scan tool.

Homes and repositions door actuators.

Monitors for door span faults. Door span faults (XXX Door Travel Range Too Large or XXX Door
Travel Range Too Small) will only display after calibration.

Will cause the electric backlight (EBL) status indicator to flash while the test is running.

Actuator DTC Detection Test

The Actuator DTC Detection Test:

Is actuated with a scan tool.

Supplements the continuous diagnostics on the actuator drive system.

Monitors for shorted actuator circuits allowing service to easily diagnose and troubleshoot up to three
simultaneous shorts. Shorted actuator circuit faults (XXX Control Circuit High or XXX Control Circuit
Low) will only display after running the Actuator DTC Detection Test.

After repairing each DTC, cycle the ignition switch, and then rerun the Actuator DTC Detection test to ensure
that no new DTCs exist. If multiple DTCs are present, beginning with the common circuits, diagnose and repair
all short high faults and then short low faults. When the test returns passed, proceed with troubleshooting by
clearing faults and running the Actuator Calibration function as a final check of proper system operation.

B1006-BI-LEVEL SWITCH REQUEST INPUT CIRCUIT PERFORMANCE

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

Theory of Operation

The Bi-Level mode switch input changes when the switch is pushed down. An active DTC indicates that the
switch is stuck in a pushed position. A stored DTC indicates that the switch was stuck in a pushed position for
more than two minutes, but has since returned to its normal state.

When Monitored:

With the ignition on.

Set Condition:

If the Bi-Level mode switch is stuck in a pushed position for more than two minutes. This DTC has a
maturing time of two minutes and a de-maturing time of two seconds. If the DTC's status changes from
active to stored it will stay in memory for 100 ignition cycles.

Possible Causes

OBJECT HOLDING SWITCH IN A PUSHED POSITION
A/C HEATER CONTROL

Diagnostic Test

1) VERIFY THE DTC IS STILL ACTIVE

Inspect the A/C Heater Control for an object holding the switch in a pushed position. If present, remove
the object.

Turn the ignition on.

With the scan tool, erase HVAC DTCs.

Turn the ignition off, wait 10 seconds, and then turn the ignition on. Wait 2 minutes before proceeding.

With the scan tool, read HVAC DTCs.

Does the scan tool display this DTC?

Yes

Replace the A/C Heater Control in accordance with the service information.

Perform BODY VERIFICATION TEST - VER 1 .

No

The condition that caused this symptom is currently not present. Check for an intermittent
condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken
wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or
contaminated terminals. Repair as necessary.

Perform BODY VERIFICATION TEST - VER 1 .

B1000-A/C SWITCH REQUEST INPUT CIRCUIT/PERFORMANCE

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

The switch input changes when the switch is pushed down. A stored DTC indicates that the A/C request switch
was stuck in a pushed position for more than 10 minutes, but has since returned to its normal state. An active
DTC indicates that the A/C request switch is stuck in a pushed position. When active, this DTC will prevent
proper A/C request switch and status indicator function.

When Monitored:

With the ignition on.

Set Condition:

If the A/C request switch is detected in a pushed position for more than 10 minutes.

Turn the ignition off, wait 10 seconds, and then turn the ignition on. Wait 10 minutes before proceeding.

With the scan tool, read HVAC DTCs.

Does the scan tool display this DTC?

Yes

Go to 2).

No

The condition that caused this symptom is currently not present. Check for an intermittent
condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken
wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or
contaminated terminals. Repair as necessary.

Perform BODY VERIFICATION TEST - VER 1 .

2) CHECK FOR NORMAL A/C REQUEST SWITCH & STATUS INDICATOR FUNCTION

Set the Blower control to any position except Off.

Set the Mode control to any position except Auto.

Press the A/C request switch on and off several times while observing the A/C status indicator.

Does the A/C status indicator turn on and off?

Yes

Go to 4).

No

Possible Causes

OBJECT HOLDING A/C MODE SWITCH IN A PUSHED POSITION
SUBSTANCE CAUSING A/C MODE SWITCH TO GET STUCK IN A PUSHED POSITION
A/C HEATER CONTROL

Go to 3).

3) INSPECT FOR OBJECT OR SUBSTANCE CAUSING THE A/C REQUEST SWITCH TO
STAY OR STICK IN A PUSHED POSITION

Inspect the A/C Heater Control for anything that would cause the A/C request switch to stay or stick in a
pushed position.

Is anything present that would cause the A/C request switch to stay or stick in a pushed position?

Yes

Repair as necessary.

Perform BODY VERIFICATION TEST - VER 1 .

No

Go to 4).

4) INSPECT THE A/C HEATER CONTROL FOR DAMAGE

Inspect the A/C Heater Control for damage.

Is the A/C Heater Control damaged?

Yes

Replace the A/C Heater Control in accordance with the service information.

Perform BODY VERIFICATION TEST - VER 1 .

No

Perform BODY VERIFICATION TEST - VER 1 .

B1003-A/C PANEL MODE SWITCH REQUEST INPUT CIRCUIT/PERFORMANCE

For complete wiring diagrams refer to SYSTEM WIRING DIAGRAMS article.

The switch input changes when the switch is pushed down. A stored DTC indicates that the panel mode switch
was stuck in a pushed position for more than 10 minutes, but has since returned to its normal state. An active
DTC indicates that the panel mode switch is stuck in a pushed position. An active DTC will prevent proper A/C
mode switch and status indicator function.

When Monitored:

With the ignition on.
