- TEST FOR INTERMITTENT CONDITION NOTE: Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing. Turn the ignition on. NOTE: Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts. With the scan tool, read the module status. NOTE: Check the TIPM for any active CAN hardware DTCs, perform DTC before proceeding. Does the scan tool indicate that the module is active on the bus? Yes The no response condition is 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. No Go To 2 .
- CHECK THE (A106) FUSED B(+) CIRCUIT FOR AN OPEN OR SHORT Turn the ignition off. Disconnect the Wireless Ignition Node harness connector. Using a 12-volt test light connected to ground, check the (A106) Fused B(+) circuit. Does the test light illuminate brightly? Yes Go To 3 . No Repair the open or short in the (A106) Fused B(+) circuit. Perform the WIN VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/door-locks-anti-theft-systems/#wireless-ignition-node-win-electrical-diagnostics) .
- CHECK THE (Z912) GROUND CIRCUIT FOR AN OPEN Using a 12-volt test light connected to 12-volts, check the (Z912) ground circuit. Does the test light illuminate brightly? Yes Go To 4 . No Repair the open in the (Z912) Ground circuit. Perform the WIN VERIFICATION TEST. Refer to «STANDARD PROCEDURE»(/jeep/grand-cherokee/wk2-2010-2013/remont/door-locks-anti-theft-systems/#wireless-ignition-node-win-electrical-diagnostics) .
- CHECK THE (D52) CAN C BUS (+) CIRCUIT FOR AN OPEN Disconnect the TIPM C7 harness connector. Measure the resistance of the (D52) CAN C Bus (+) circuit between the TIPM C7 harness connector and the Wireless Ignition Node harness connector. Is resistance below 5.0 Ohms? Yes Go To 5 . No Repair the open in the (D52) CAN C Bus (+) circuit. 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) .
- CHECK THE (D51) CAN C BUS (-) CIRCUIT FOR AN OPEN Measure the resistance of the (D51) CAN C Bus (-) circuit between the TIPM C7 harness connector and the Wireless Ignition Node harness connector. Is resistance below 5.0 Ohms? Yes Replace the Wireless Ignition Node in accordance with the Service Information. Refer to «RECEIVER, WIRELESS IGNITION NODE , 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 Repair the open in the (D51) CAN C Bus (-) circuit. 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) .

Bus messages not received for approximately two to five seconds.
| Possible Causes |
|---|
| CAN C BUS CIRCUITS OPEN OR SHORT |
| CAN C INTERIOR BUS CIRCUITS OPEN OR SHORT |
| DTCS RELATED TO BATTERY VOLTAGE, IGNITION, OR VIN MESSAGES |
| TIPM NOT CONFIGURED CORRECTLY |
| POWER OR GROUND FROM THE REPORTING MODULE |
| MODULE THAT SET THIS DTC |
| PREVIOUS SERVICE PERFORMED WITHIN THE LAST 100 KEY CYCLES (FUSE/RELAYS REMOVED, WIRING SERVICE, BATTERY DISCONNECT) |
| LOW BATTERY/JUMP START CONDITION |
| IOD FUSE WAS REMOVED DURING SHIPPING |
| CHECK FOR RELATED TSBS |
- VERIFY DIAGNOSTIC TROUBLE CODE (DTC) IS STORED NOTE: Stored faults may indicate a customer perceived intermittent condition. NOTE: Make sure the IOD fuse is installed and battery voltage is between 10 and 16 volts before proceeding. Turn the ignition on. With the scan tool, read stored DTCs. Is this DTC stored? Yes Go To 2 . No Go to the appropriate Electrical Diagnostic Information and perform the appropriate diagnostic procedure.
- CHECK THE ENVIRONMENTAL DATA With the scan tool, read the loss of communication environmental data. Does the loss of communication environmental odometer data match up to any of the previous service procedures listed in the possible causes or are there any stored CAN C hardware electrical, battery, ignition voltage, VIN missing/mismatch, or TIPM configuration DTCs present with matching environmental data? Yes These DTCs may have been the result of other service procedures performed. Clear the DTCs. 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 Go To 3 .
- VERIFY INTERMITTENT LOST COMMUNICATION DTC - WIRING CONCERNS With the scan tool, select Network View and select Advanced. Is there more than one ECU with stored DTCs "Logged Against" the module and one or more lost communication DTCs stored in the offending module? Yes Verify if the vehicle was recently in for this type of service. Otherwise, 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. Repair as necessary. No Go To 4 .
- VERIFY INTERMITTENT LOST COMMUNICATION DTC - OFFENDING MODULE With the scan tool, select Network View and select Advanced. Is there more than one ECU with stored DTCs "Logged Against" the module and NO lost communication DTCs stored in the offending module? Yes Check for a TSB related to this offending module. No Go To 5 .
- VERIFY INTERMITTENT LOST COMMUNICATION DTC - REPORTING MODULE With the scan tool, select Network View and select Advanced. Is there ONLY ONE ECU with stored DTCs "Logged Against" the module? Yes Check for a TSB related to the module that set this DTC. No Verify if the vehicle was recently in for this type of service. Otherwise, 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. Repair as necessary.
