Pinpoint Tests
PINPOINT TEST G239843p1 : CHECK
THE CONTROLLER AREA NETWORK
FOR OPEN CIRCUIT
G239843t1 : CHECK THE CAN NETWORK FOR CONTINUITY
1. Measure the resistance between DLC, pins 06 (Y) and 14 (G).
•
Is the resistance 60 ohms?
-> Yes
GO to Pinpoint Test G239843t2.
-> No
GO to Pinpoint Test G239843t10.
G239843t2 : CHECK THE REAR CLIMATE CONTROL CONTROL MODULE
(RCCM) CAN + CIRCUIT FOR CONTINUITY
1. Disconnect the RCCM electrical connector, RA01. 2. Measure the resistance between DLC, pin 06
(Y) and RA01, pin 08 (Y).
•
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the
DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G239843t3.
G239843t3 : CHECK THE REAR CLIMATE CONTROL CONTROL MODULE
(RCCM) CAN - CIRCUIT FOR CONTINUITY
1. Measure the resistance between DLC, pin 14 (G) and RA01, pin 16 (G).
•
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the
DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G239843t4.
G239843t4 : CHECK THE YAW RATE SENSOR CAN + CIRCUIT FOR
CONTINUITY
1. Disconnect the Yaw rate sensor electrical connector, IP23. 2. Measure the resistance between DLC,
pin 06 (Y) and IP23, pin 02 (Y).
•
Is the resistance greater than 5 ohms?
-> Yes
REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the
DTC. TEST the system for normal operation.
-> No
GO to Pinpoint Test G239843t5.
