PINPOINT TEST E: DTC U2005 — ACP COMMUNICATION ERROR BETWEEN INTEGRATED CONTROL PANEL AND REMOTE CLIMATE CONTROL MODULE
 Is the resistance less than 5 ohms?
D4 CHECK CIRCUIT 398 (BK/YE) FOR AN OPEN
 Measure the resistance between the solar radiation sensor C287 pin 5, circuit 398 (BK/YE).
 Is the resistance less than 5 ohms?
Yes
INSTALL a new RCC module. TEST the system for normal
operation.
No
REPAIR circuit 398 (BK/YE) for an open. TEST the system for
normal operation.
D5 CHECK CIRCUIT 468 (BN) FOR A SHORT TO CIRCUIT 398 (BK/YE)
 Ignition OFF.
 Disconnect: RCC Module C228.
 Measure the resistance between the solar radiation sensor C287 pin 1, circuit 468 (BN) and pin 5, circuit
398 (BK/YE).
 Is the resistance greater than 10,000 ohms?
Yes
GO to D6.
No
REPAIR circuit 468 (BN) for a short to circuit 398 (BK/YE).
TEST the system for normal operation.
D6 CHECK CIRCUIT 468 (BN) FOR A SHORT TO GROUND
 Measure the resistance between the solar radiation sensor C287 pin 1, circuit 468 (BN) and ground.
 Is the resistance greater than 10,000 ohms?
Yes
INSTALL a new RCC module. TEST the system for normal
operation.
No
REPAIR circuit 468 (BN) for a short to ground. TEST the system
for normal operation.
