ACTIVE DESCENT CONTROL (ADC) COIL (6X6)
Operation Overview
• AWD switch must be ‘ON’. 12Vdc power is present at the ADC hub coil.
• ECU pin #11 controls the grounding of the ADC hub coil for operation.
• ECU Pin #20 senses the gear signal indicating the transmission is engaged and is not in Park or Neutral.
• ECU pin #27 senses the speed sensor signal for determining if vehicle speed is below 15 Mph.
• ECU senses 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 meter.
ADC Hub Coil Resistance:
12 Ohms ± 5%
