ELECTRICAL

ACTIVE DESCENT CONTROL (ADC)
COIL

Operation Overview

• AWD switch must be ‘ON’.

• PDM pin ‘M’ on SSCB #1 controls the power to the

ADC hub coil for operation.

• PDM pin ‘C’ on SSCB #1 senses the gear signal

indicating the transmission is engaged and is not in Park
or Neutral.

• PDM pin ‘K’ on SSCB #2 senses the speed sensor

signal for determining if vehicle speed is below 15
Mph.

• ECU pin #21 sends a signal to PDM pin ‘D’ on SSCB

#1 to determine the TPS position and will cancel ADC
operation if TPS moves off ‘idle’ position.

• System must be grounded to operate.

Diagnosing System Failures

• Verify the AWD switch is functional.

• Verify the ADC hub coil is functional. Test the ADC

hub coil using an ohm meter.

• Verify the TPS is functioning correctly. Test using

Digital Wrench Diagnostic Software. (Dealer Only)

• Verify the wiring harness, wiring, connectors,

connector pins, grounds and PDM / ECU pin locations
are undamaged, clean and connect properly.

• Verify continuity of wire connections with a known

good volt/ohm meter.

IMPORTANT: Verify all wires and wiring connections

have been tested properly with a known good volt/

ohm meter before suspecting a component failure.

80% of all electrical issues are caused by bad/failed

connections and grounds.

NOTE: Refer to the ADC subsystem diagram located
in ‘Wire Diagrams’ at the end of this chapter.

ALL WHEEL DRIVE (AWD) COIL

Operation Overview

• AWD switch must be ‘ON’. 12Vdc power is present at

the ADC hub coil.

• The instrument cluster senses grounding at pin #16.

AWD icon should turn on at the instrument cluster.

• System must be grounded to operate.

Diagnosing System Failures

• Verify the AWD switch is functional.

• Verify the AWD hub coil is functional. Test the AWD

hub coil using an ohm meter.

• Verify the wiring harness, wiring, connectors,

connector pins and grounds are undamaged, clean and
connect properly.

• Verify continuity of wire connections with a known

good volt/ohm meter.

IMPORTANT: Verify all wires and wiring connections

have been tested properly with a known good volt/

ohm meter before suspecting a component failure.

80% of all electrical issues are caused by bad/failed

connections and grounds.
