1 | Did you perform the Instrument Cluster Diagnostic System Check? | -- | Go to Step 2 | |
2 | Verify that the compass is inaccurate or inoperative or that CALIBRATE COMPASS is displayed. Does the system operate normally? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 |
Do all of the compass display segments illuminate? | -- | Go to Step 4 | Go to Step 16 |
4 | Perform the compass calibration procedure. Refer to Electronic Compass Calibration . Does the compass operate properly? | -- | Go to Step 18 | Go to Step 5 |
5 | Perform the compass variance procedure. Refer to Electronic Compass Calibration . Does the compass operate properly? | -- | Go to Step 18 | Go to Step 6 |
6 |
Does the test lamp illuminate? | -- | Go to Step 7 | Go to Step 14 |
7 |
Does the voltage measure near the specified value? | B+ | Go to Step 8 | Go to Step 15 |
8 | Measure the voltage between the compass clock signal circuit and a good ground. Does the voltage measure near the specified value? | B+ | Go to Step 9 | Go to Step 10 |
9 | Test the compass clock signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | Go to Step 11 |
10 | Test the compass clock signal circuit for an open or a high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | Go to Step 12 |
11 | Test the compass data signal circuit for a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | Go to Step 13 |
12 | Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | Go to Step 16 |
13 | Inspect for poor connections at the harness connector of the electronic compass module. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | Go to Step 17 |
14 | Repair the open, the high resistance, or the short to ground in the ignition 3 voltage circuit of the electronic compass module. Refer to Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | -- |
15 | Repair the open or the high resistance in the rear defog relay control circuit. Refer to Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 18 | -- |
16 | Replace the IPC. Refer to Instrument Cluster Replacement . Did you complete the replacement? | -- | Go to Step 18 | -- |
17 |
Important: Perform the calibration and variance procedure for the replacement electronic compass module. Replace the electronic compass module. Refer to Electronic Compass Module Replacement . Did you complete the replacement? | -- | Go to Step 18 | -- |
18 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
