3. Disconnect the ADCM electrical connector, CA011.
4. Measure the resistance between the diagnostic connector FC001, pin 10 (U) and CA011, pin 013 (U).
-
Is the resistance less than 5 ohms?
-> Yes
-> No
REPAIR the SCP - circuit. CLEAR the DTC. TEST the system for normal operation.
G195523t122 : CHECK FOR CORRECT BUS TERMINATION ON SCP +
1. Turn the ignition switch to the OFF position.
2. Disconnect the battery negative terminal.
3. Reconnect the ADCM electrical connector, CA011.
4. Measure the resistance between the diagnostic connector FC001, pin 2 (Y) and GROUND.
-
Is the resistance 90 to 150 ohms?
-> Yes
INSTALL a new ADCM. CLEAR the DTC. TEST the system for normal operation.
-> No
G195523t123 : CHECK THE CONTINUITY OF THE FRONT ELECTRONIC MODULE (FEM) SCP + CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Disconnect the battery negative terminal.
3. Disconnect the FEM electrical connector, FH059.
4. Measure the resistance between FC001, pin 2 (Y) and FH059, pin 7 (Y).
-
Is the resistance less than 5 ohms?
-> Yes
-> No
REPAIR the circuit. CLEAR the DTC. TEST the system for normal operation.
G195523t124 : CHECK FOR LOSS OF SCP + TERMINATION WITHIN THE FEM
1. Turn the ignition switch to the OFF position.
2. Disconnect the battery negative terminal.
3. Disconnect the FEM electrical connectors, FH059, and FH060.
4. Measure the resistance between FH059, pin 007 (Y), and FH060, pin 011 (Y) of the FEM. (Reconnect the FEM following completion of the test).
-
Is the resistance 140 to 220 ohms?
-> No
-> Yes
INSTALL a new FEM.
G195523t125 : CHECK THE CONTINUITY OF THE REAR ELECTRONIC MODULE (REM) SCP + CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Disconnect the battery negative terminal.
3. Disconnect the REM electrical connector, CA102.
4. Measure the resistance between FC001, pin 2 (Y) and CA102, pin 001 (Y).
-
Is the resistance less than 5 ohms?
-> Yes
-> No
REPAIR the circuit. CLEAR the DTC. TEST the system for normal operation.
