G4 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0142:XX SET IN OTHER MODULES
Using the diagnostic scan tool, carry out the self-test for all modules. Retrieve and record the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0142:xx set in 1 or more modules in addition to the Moveable Roof Control Module A (MRCMA)?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCMB. REFER to: Body Control Module B (BCMB) (419-10 Multifunction Electronic Modules, Removal and Installation). | |

G5 CHECK THE ELECTRICAL CONNECTORS
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
Ignition OFF. Disconnect Moveable Roof Control Module A (MRCMA) C4830. Disconnect BCMB C4368A. Using a good light source, inspect each connector for the following:
corrosion - install new connector or terminal and clean the module pins damaged or bent pins - install new terminals or pins pushed-out pins - install new pins as necessary
Using a suitable mating terminal, check the following connector terminals for deformed or enlarged contacts:
C4830-9 C4830-10 C4368A-11 C4368A-23
Are both connectors free of corrosion, pushed-out pins and deformed or enlarged contacts?
Yes | The system is operating correctly at this time. The DTC may have been set due to high network traffic, a loose connector, a corroded connector or an intermittent fault condition. ADDRESS the root cause of any connector or pin issues. | |
|---|---|---|
No | REPAIR the affected connector. Refer to Wiring Diagrams Cell 5 for schematic and connector information. | |
U0294:00
Refer to Wiring Diagrams Cell 103 for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the PCM sends messages to the Moveable Roof Control Module A (MRCMA) through the GWM over the HS-CAN1. If the Moveable Roof Control Module A (MRCMA) does not receive these messages within a certain time frame, the module sets a DTC. For information on the messages sent to the Moveable Roof Control Module A (MRCMA) by the PCM, refer to the Network Message Chart.
