Battery voltage between 10 and 16 volts.

Ignition Off Draw (IOD) fuse installed.

Totally Integrated Power Module (TIPM) is configured correctly.

Bus messages not received from the Central Gateway for approximately two to five seconds.

1. VERIFY DTC IS ACTIVE NOTE: Make sure the IOD fuse is installed and the battery is fully charged before proceeding. Turn the ignition on. With the scan tool, read active DTCs. Is this DTC active? Yes Refer to «DIAGNOSIS AND TESTING»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-dtcs-b10b4-to-b25ae) and perform the U0141-Lost Communication with IPM (FCM/TIPM) diagnostic procedure. No Refer to «DIAGNOSIS AND TESTING»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#communication-non-dtc-based-diagnostics) and perform the Stored Lost Communication DTCs diagnostic procedure.

U0155-00-LOST COMMUNICATION WITH CLUSTER/CCN

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Continuously when the ignition is on.

Battery voltage between 10 and 16 volts.

Ignition Off Draw (IOD) fuse installed.

Totally Integrated Power Module (TIPM) is configured correctly.

Bus messages not received from the Instrument Cluster (CCN) for approximately two to five seconds.

1. VERIFY DTC IS ACTIVE NOTE: Make sure the IOD fuse is installed and the battery is fully charged before proceeding. Turn the ignition on. With the scan tool, read active DTCs. Is this DTC active? Yes Refer to «DIAGNOSIS AND TESTING»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-dtcs-b10b4-to-b25ae) and perform the U0155-Lost Communication with Cluster/CCN diagnostic procedure. No Refer to «DIAGNOSIS AND TESTING»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#communication-non-dtc-based-diagnostics) and perform the Stored Lost Communication DTCs diagnostic procedure.

U1008-00-LIN 1 BUS

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

The Right Steering Wheel Switch communicates with the Steering Column Control Module (SCCM) via the LIN Bus. The SCCM is located near the top of the steering column below the steering wheel. The SCCM includes the steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multi-function Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover. The SCCM is replaced as an entire assembly.

Continuously with the ignition on.

Fault signifies when the LIN Bus is shorted to ground, shorted to battery, or a defective Right Steering Wheel Switch (Speed Control Switch).

1. CHECK FOR AN ACTIVE DTC Turn the ignition on. With the scan tool, read DTCs Does the scan tool display this DTC as active? Yes WARNING: Turn the ignition off disconnect the 12-volt battery and wait two minutes before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. WARNING: Do not place an intact non-deployed airbag face down on a hard surface, the airbag propels into the air if accidentally deployed. Failure to follow these instructions may result in possible serious or fatal injury. NOTE: Visually and physically inspect the wiring harness between the Right Steering Wheel Switch (Speed Control Switch) harness connector and the SCCM harness connector. Repair any damaged wires, connectors, and open/spread terminals. If harness is OK, view repair. Replace the Right Steering Wheel Switch (Speed Control Switch) in accordance with the Service Information. Refer to «SWITCH, SPEED CONTROL , REMOVAL»(/jeep/grand-cherokee/wk2-2010-2013/remont/cruise-control-systems/#speed-control-service-information__removal) . Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-body-verification-test) . No Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-body-verification-test) .

U1175-00-LOST IGNITION STATUS MESSAGE

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Continuously when the ignition is on.

The Steering Control Module does not receive the Ignition Switch status over the CAN Bus.

1. CHECK FOR AN ACTIVE DTC NOTE: Make sure the IOD fuse is installed and the battery is fully charged before proceeding. NOTE: Diagnose any CAN Bus DTCs that may be set in other modules before proceeding with this diagnostic procedure. Turn the ignition on. With the scan tool, read active DTCs. Dose the scan tool display this DTC as active? Yes If no other CAN Bus DTCs are set in other modules and the SCCM is the only one reporting this DTC, replace the SCCM in accordance with the Service Information. Refer to «MODULE, STEERING COLUMN , REMOVAL»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#electronic-control-modules-service-information) . Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-body-verification-test) . No Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension. Perform the BODY VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/communication-devices/#totally-integrated-power-module-tipm-body-verification-test) .
