MKS AWD V6-3.7L (2009)
-
Is the concern still present?
Yes
INSTALL a new DCSM. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the
network test with the scan tool.

Normal Operation
The Parking Aid Module (PAM) communicates with the scan tool through the Medium Speed Controller Area Network (MS-CAN). Circuits VDB06
(GY/OG) (MS-CAN +) and VDB07 (VT/OG) (MS-CAN -) provide the network connection to the PAM. Voltage for the PAM is provided by circuit
CBP35 (YE/GY). Circuit GD149 (BK/GY) provides ground.
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
PAM
PINPOINT TEST Q: THE PAM DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
-------------------------------------------------
Q1 CHECK THE PAM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: PAM C4014 (Rear) or C4226a (Front and Rear).
-
Ignition ON.
-
Measure the voltage between the PAM C4014-1 or C4226a-1, circuit CBP35 (YE/GY), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to Q2.
No
VERIFY the Smart Junction Box (SJB) fuse 35 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams to identify the
possible causes of the short circuit. TEST the system for normal operation.
