Circuit/System Verification
Ignition ON, verify that when the DIC switches are pressed and released the DIC scan tool parameters toggle between Active and Inactive.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the DIC switch assembly.
2. Ignition OFF, test for less than 1 ohm between the low reference terminal 2 and ground.
瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance.
3. Ignition OFF, test for less than 5 ohms between the ground circuit terminal 5 and ground.
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
4. Ignition ON, verify that all of the scan tool DIC Switch parameters are Inactive.
瀚慖f any are not Inactive, test the signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the IPC.
* DIC Switch Signal Terminal 1
* DIC Select Switch Signal Terminal 3
5. Ignition ON, install a 3A fused jumper wire between the signal circuit terminal 1 and the low reference circuit terminal 2. Verify the scan tool
DIC Switch parameters, except the DIC Fuel Info. parameter, are Active.
瀚慖f any are not Active, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the IPC.
6. Ignition ON, install a 3A fused jumper wire between the signal circuit terminal 3 and ground. Verify the scan tool DIC Fuel Info. parameter
is Active.
瀚慖f not Active, test the signal circuit for a short to voltage or and open/high resistance. If the circuit tests normal, replace the IPC.
7. If all the circuits test normal, test or replace the DIC switch assembly.
