2006 DODGE RAM SRT-10 wiring diagram

For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C Heater Control drives the Blend Door Actuator via the (C61) Blend Door Driver circuit and the (C34) Com-
mon Door Driver circuit. The A/C Heater Control drives the Mode Door 1 (Panel to Floor) Actuator via the (C29)
Mode Door 1 Driver circuit and the (C34)CommonDoorDrivercircuit.TheA/CHeater Control drives the Mode
Door 2 (Defrost to Floor) Actuator via the (C801) Mode Door 2 Driver circuitand the (C34) Common Door Driver
circuit. The A/C Heater Control drives the Recirculation Door Actuator via the (C32) Recirculation Door Driver circuit
and the (C34) Common Door Driver circuit. All of the door actuators share the (C34) Common Door Driver circuit.
Inside the A/C Heater Control, each door actuator has its own unique driver, but all share a single common door
driver circuit. Due to the shared circuitry similar DTCs can set at the sametime for multiple actuators depending
upon the type of short, its location, and the direction the actuator is moving when the short is present.
When Monitored:
When the Actuator DTC Detection Test is executed.
Set Condition:
If the (C34) Common Door Driver circuit is shorted to ground.
Possible Causes
(C34) COMMON DOOR DRIVER CIRCUIT SHORTED TO GROUND
(C34) COMMON DOOR DRIVER CIRCUIT SHORTED TO OTHER DOOR DRIVER CIRCUIT(S)

10.RUN THE ACTUATOR DTC DETECTION TEST
Reconnect the A/C Heater Control C1 harness connector.
Turn the ignition on.
With the scan tool in HVAC, select System Tests and then select Actuator DTCDetection. When the test is com-
plete, select View DTCs.
Does the scan tool only display: B105F–CLIMATE CONTROL MOTOR(S) COMMON 1 CONTROL CIRCUIT
LOW?
Ye s>>
Replace the A/C Heater Control in accordance with the Service Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).
No, Other DTC(s) Displayed
Diagnose and repair the other DTC(s). If multiple DTCs are present, beginning with the common circuit,
diagnose and repair all short high DTCs and then all short low DTCs. Refer tothe Table of Contents in
this Section for a complete list of HVAC related symptoms.
No, And No DTCs Displayed
Using the wiring diagram as a guide, inspect the wiring and connectors for conditions causing an inter-
mittent short. Repair as necessary.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).

B1001–A/C SWITCH REQUEST INPUT CIRCUIT LOW (SINGLE-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C mode switch input changes when the switch is pushed down. A stored DTC B1001 indicates that the A/C
mode switch was stuck in a pushed position for more than two minutes, but hassince returned to its normal state.
An active DTC B1001 indicates that the A/C mode switch is stuck in a pushed position.AnactiveDTCB1001will
also prevent proper A/C mode switch and status indicator function as evidenced by not being able to turn the A/C
status indicator either on if off or off if on.
When Monitored:
With the ignition on.
Set Condition:
If the A/C mode switch stays 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
A/C HEATER CONTROL DAMAGED
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
Diagnostic Test
1.INSPECT THE A/C HEATER CONTROL FOR DAMAGE
Inspect the A/C Heater Control for damage.
Is the A/C Heater Control damaged?
Ye s>>
Replace the A/C Heater Control in accordance with the Service Information.
Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE).

2.INSPECT FOR OBJECT OR SUBSTANCE CAUSING THE A/C MODE SWITCH TO STAY OR STICKIN A
PUSHED POSITION
Inspect the A/C Heater Control for anything that would cause the A/C mode switch to stay or stick in a pushed
position.
Is anything present that would cause the A/C mode switch to stay or stick in apushed position?
Ye s>>
Repair as necessary.

B1016–REAR DEFROST SWITCH REQUEST INPUT CIRCUIT LOW (SINGLE-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The Rear Defrost mode switch input changes when the switch is pushed down. Astored DTC B1016 indicates that
the Rear Defrost mode switch was stuck in a pushed position for more than twominutes, but has since returned to
its normal state. An active DTC B1016 indicates that the Rear Defrost mode switch is stuck in a pushed position. An
active DTC B1016 will also prevent proper Rear Defrost mode switch and status indicator function as evidenced by
not being able to turn the Rear Defrost status indicator either on if off or off if on.
When Monitored:
With the ignition on.
Set Condition:
If the Rear Defrost mode switch stays in a pushed position for more than two minutes. This DTC has a matur-
ing 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.

B1031–EVAPORATOR TEMPERATURE SENSOR CIRCUIT LOW
For a complete wiring diagramRefer to Section 8W.

B1032–EVAPORATOR TEMPERATURE SENSOR CIRCUIT HIGH
For a complete wiring diagramRefer to Section 8W.

B1040–PANEL MODE DOOR 1 CONTROL CIRCUIT/PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C Heater Control monitors the door driver circuits during actuator operation for shorts to ground, shorts to
battery, and shorts to other door driver circuits. If detected, the A/C Heater Control reports these types of faults as
Control Circuit/Performance DTCs. It is important to note that Control Circuit/Performance DTCs do not indicate
where or what type of short is present and that additional system testing isnecessary to provide more details about
the reported fault.
When Monitored:
When actuator movement is requested.
Set Condition:
If the A/C Heater Control detects an excessive current draw on any of the door driver circuits while attempting
to drive this actuator. This DTC has a maturing time of 5 seconds and a de-maturing time of 10 seconds. If the
DTC’s status changes from active to stored it will stay in memory for 100 ignition cycles.
Possible Causes
DOOR DRIVER CIRCUIT(S) SHORTED
NOTE:TheDTCmustbeactivefortheresultsofthistesttobevalid.Donotperform this test if the DTC is
stored. Refer to HVAC System Test for stored DTC test procedures.
Diagnostic Test
