1 | Did you review the Instrument Cluster Description and perform the necessary inspections? | Go to Step 2 | |
2 | Verify the outside temperature display is inaccurate or inoperative. Does the system operate normally? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3 |
3 | Measure the resistance between cavity 1 and 2 of the ambient air temperature sensor. Refer to Ambient Air Temperature Sensor Resistance for proper resistance specifications. Is resistance within specs? | Go to Step 4 | Go to Step 11 |
4 | With the ignition in the ON position. Test cavity 1 of the ambient air temperature sensor harness connector for a 5-volt reference signal. Refer to Circuit Testing . Is the voltage present? | Go to Step 5 | Go to Step 6 |
5 | Test cavity 2 of the ambient temperature sensor harness connector for continuity to ground. Refer to Circuit Testing . Is a ground present? | Go to Step 10 | Go to Step 7 |
6 | With the ignition in the ON position, test cavity 38 of the instrument panel cluster harness connector for a 5-volt reference signal. Refer to Circuit Testing . Is the voltage present? | Go to Step 8 | Go to Step 10 |
7 | Test cavity 39 of the Instrument panel cluster harness connector for continuity to ground. Is a ground present? | Go to Step 9 | Go to Step 10 |
8 | Repair the open or high resistance in 5-volt referance circuit between cavity 38 of the I/P cluster and caity 1 of the ambient air temperature sensor. Refer to Wiring Repairs . Did you complete the repair? | Go to Step 12 | -- |
9 | Repair the open or high resistance in the ambient temperature sensor ground circuit between cavity 39 of the I/P cluster and cavity 2 of the ambient temperature sensor Refer to Wiring Repairs . Did you complete the repair? | Go to Step 12 | -- |
10 | Replace the instrument panel cluster. Refer to Instrument Cluster Replacement . Did you complete the replacement? | Go to Step 12 | -- |
11 | Replace the ambient air temperature sensor. Did you complete the repair? | Go to Step 12 | -- |
12 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
