2. (A411) FUSED B(+) CIRCUIT OPEN OR SHORTED Turn the ignition off. Disconnect the Sentry Key Remote Entry Module harness connector. Using a 12-volt test light connected to ground, check the (A411) Fused B(+) circuit. Does the test light illuminate brightly? Yes Go To step 3 . No Repair the (A411) Fused B(+) circuit for an open or short. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-305788-S17210067822008120200000) .
3. (Z910) GROUND CIRCUIT OPEN Using a 12-volt test light connected to 12-volts, check the (Z910) ground circuit. Does the test light illuminate brightly? Yes Go To step 4 . No Repair the (Z910) ground circuit for an open. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-305788-S17210067822008120200000) .
4. (F20) IGNITION SWITCH OUTPUT CIRCUIT OPEN OR SHORTED Turn the ignition on. Using a 12-volt test light connected to ground, check the (F20) Ignition Switch Output circuit. Does the test light illuminate brightly? Yes Go To step 5 . No Repair the (F20) Ignition Switch Output circuit for an open or short. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-305788-S17210067822008120200000) .
5. (D55) AND (D54) CAN B BUS CIRCUITS OPEN NOTE: One open circuit will not cause this condition. Measure the voltage between the (D54) CAN B Bus (-) circuit and ground. Measure the voltage between the (D55) CAN B Bus (+) circuit and ground. Is there any voltage present on either circuit? Yes Replace the Sentry Key Remote Entry Module in accordance with the service information. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-305788-S17210067822008120200000) . No Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-305788-S17210067822008120200000) .

1. When Monitored: With the ignition on. Battery voltage between 10 and 16 volts. IOD fuse installed. TIPM is configured correctly.

1. Set Condition: Bus messages not received for approximately 2 to 5 seconds.
