Test Procedures

KR1 DTC P0A14: CHECK THE FUNCTIONALITY OF THE AMC CIRCUIT AT THE SOLENOID

NOTE: If the active mount has been replaced with a non-active mount, the active mount solenoid vacuum port will be capped.

Connect a non-powered test lamp between:

( + ) AMC Actuator Connector, Harness Side	(-) AMC Actuator Connector, Harness Side
VPWR-Pin 1-(361e)	AMC - Pin 2-(99)

Does the test lamp illuminate on and off when the AMC output is commanded on and off?

Yes	No
GO to KR2	GO to KR3

KR2 CHECK THE COMPONENT RESISTANCE

Measure the resistance between:

( + ) AMC Actuator Connector, Component Side	(-) AMC Actuator Connector, Component Side
VPWR-Pin 1-(361e)	AMC - Pin 2-(99)

Is the resistance between 68 ohms - 78 ohms?

Yes	No
Unable to duplicate or identify the fault at this time. GO to KR7	INSTALL a new AMC actuator.

KR3 CHECK THE VPWR VOLTAGE TO THE COMPONENT

Measure the voltage between:

( + ) AMC Actuator Connector, Harness Side	(-) Vehicle Battery
VPWR-Pin 1-(361e)	Negative terminal

Is the voltage greater than 10.5 V?

Yes	No
Key in OFF position. GO to KR4	Key in OFF position. REPAIR the open circuit. CHECK the condition of related fuses/fuse links. If damaged, CHECK the VPWR circuit for a short to ground.

KR4 CHECK THE AMC CIRCUIT FOR A SHORT TO POWER IN THE HARNESS

Measure the voltage between:

( + ) AMC Actuator Connector, Harness Side	(-) Vehicle Battery
AMC - Pin 2-(99)	Negative terminal

Is the voltage less than 1 V?

Yes	No
GO to KR5	Key in OFF position. REPAIR the short circuit to PWR.

KR5 CHECK THE AMC CIRCUIT FOR AN OPEN IN THE HARNESS

Measure the resistance between:

( + ) AMC Actuator Connector, Harness Side	(-) PCM Connector, Harness Side
AMC - Pin 2-(99)	AMC - Pin E2

Is the resistance less than 5 ohms?

Yes	No
GO to KR6	REPAIR the open circuit.

KR6 CHECK THE AMC CIRCUIT FOR A SHORT TO GROUND IN THE HARNESS

Measure the resistance between:

( + ) AMC Actuator Connector, Harness Side	(-) Vehicle Battery
AMC - Pin 2-(99)	Negative terminal

Is the resistance greater than 10K ohms?

Yes	No
INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) .	REPAIR the short circuit to GND.

KR7 CHECK THE AMC CIRCUIT FOR AN INTERMITTENT CONCERN

PCM connector connected.
AMC Actuator connector connected.
Key in ON position.
Access the PCM and control the AMC PID.
Command the AMC ON.
Access the PCM and monitor the AMC_FLT PID.
Carefully wiggle all accessible wiring and connectors associated with the circuit and look for a change in the PID state.

Is a fault indicated during the wiggle test?

Yes	No
Key in OFF position. REPAIR as necessary.	Key in OFF position. GO to Pinpoint Test Z .
