Diagnostic Test

TEST FOR INTERMITTENT CONDITION
1. Turn the ignition on.
  NOTE: Make sure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
2. Using the scan tool, select ECU View.
  NOTE: A red "X" will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.
  
  NOTE: Check the TIPM for any active CAN C hardware DTCs, and perform DTC(s) before proceeding.
  
  Does the scan tool display a red "X" next to the module?
  
  Yes
  - Go to Step 2.
  No
  - The no response condition is not present at this time. Using the appropriate wiring diagram as a guide, inspect the wiring for chafed, pierced, pinched and partially broken wires and the wiring harness connectors for broken, bent, pushed out and corroded terminals.
