Display information for the Engine Vision Interface Module (EVIM).
(1) Cat Data Link Receive Active
(2) Transmit to Engine Vision.
(3) Receive a Signal from Engine Vision. Test Step 1. Inspect the Electrical Connectors and the Wiring
Turn the keyswitch to the "OFF" position.
Check the connections to the Electronic Control Module (ECM). Check the ECM connectors, the customer connector, and the wiring for damage or for incorrect attachment.
Check for the correct installation of the wires for the Cat Data Link. Refer to Installation Guide, "Wiring the Cat Data Link" for additional information.
Check the following components for abrasion, for corrosion, or for incorrect attachment.
