Table 98
Troubleshooting Test Steps
Values Results
1. Determine the Code
A. Connect the electronic service tool to the service tool connector.
Refer to Troubleshooting, “Electronic Service Tools”, if necessary.
B. Turn the keyswitch to the ON position.
C. Check if one of the diagnostic codes listed in Table 97 is active
or logged.
Diagnostic
Codes
Result: A -2 diagnostic code is active.
Note which 5 V supply is reporting the active sensor supply
code.
Proceed to Test Step 2.
Result: A -2 diagnostic code is logged.
An intermittent fault may be present. Refer to Troubleshoot-
ing, “Electrical Connectors - Inspect” in order to identify inter-
mittent faults.
2. Check for a Failed Sensor
A. Connect to the electronic service tool.
B. Turn the keyswitch to the ON position.
C. Disconnect a sensor on the suspect sensor supply circuit.
D. Monitor the electronic service tool while the sensor is discon-
nected to see if the active code changes to logged.
E. Connect the suspect sensor to the wiring harness
F. Repeat steps C through E for each sensor on the suspect sensor
supply.
Failed
Sensor
Result: The suspect sensor supply active code changes to
logged when a sensor is unplugged.
Repair: Replace the failed sensor.
Verify that the repair resolved the problem.
Result: The suspect sensor supply active code remains ac-
tive after all sensors on the sensor supply circuit have been
checked.
Repair: The fault is in the wiring harness.
Check all wiring on the suspect sensor supply. Refer to the
appropriate Electrical Schematic.
Replace the faulty wiring.
If the procedure did not correct the fault, contact the Dealer Solution Network (DSN).
