Ignition off.
Remove fuse FX in the Central electronic module (CEM).
Release the Keyless vehicle module (KVM). See: KEYLESS VEHICLE MODULE (KVM)
Disconnect the connectors from the Keyless vehicle module (KVM).
Check in particular that the male and female terminals on the control module and the control module connector are intact, secure and cannot be pressed in. Check that the female terminal cables are securely connected
Especially check the pins that are in question for the diagnostic trouble code/symptom. See: SIGNAL SPECIFICATION
Connect adapter (See: 9512906 ) to the connectors for the Keyless vehicle module (KVM) and connect breakout box (see: 9511428 ) to the adapter.
NOTE:
Before the control module functions can be checked and measurements taken, the removed fuses must first be installed.
The breakout box is designed to facilitate the reading of control module input and output signals when the control module is connected as well as the resistance of cables and components when the control module is disconnected. Using the breakout box reduces the risk of unintentionally short-circuiting cables or damaging pins in the connectors.
