1. 1) CHECK FOR ACTIVE DTC U0019-CAN B BUS Turn the ignition on. With the scan tool, record and erase any Electronic Overhead Module DTCs. Turn the ignition off, wait 30 seconds then turn the ignition on. With the scan tool, read DTCs. Is DTC U0019-CAN B BUS active? Yes Go To 2) . No The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Perform BODY VERIFICATION TEST - VER 1. «(Refer to BODY VERIFICATION TEST - VER 1)»(ref-255944-S31737016002007060500000) .
2. 2) CHECK FOR ACTIVE CAN B BUS RELATED DTCS IN THE FRONT CONTROL MODULE With the scan tool, read Front Control Module DTCs Does the scan tool display any active CAN B BUS related DTCs? Yes Diagnose and repair the DTC(s). «(Refer to ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING)»(ref-255952-S37788235782007060500000) No Go to 3) .
3. 3) CHECK (D55) CAN B BUS (+) CIRCUIT FOR AN OPEN Turn the ignition off. Disconnect the negative battery cable. Disconnect the Electronic Overhead Module harness connector. Disconnect the Front Control Module C1 harness connector. Measure the resistance of the (D55) Can B Bus (+) circuit between the Front Control Module C1 harness connector and the Electronic Overhead Module harness connector. Is the resistance below 2.0 ohms? Yes Go To 4) . No Repair the Can B Bus (+) circuit for an open. Perform BODY VERIFICATION TEST - VER 1. «(Refer to BODY VERIFICATION TEST - VER 1)»(ref-255944-S31737016002007060500000) .
4. 4) CHECK THE (D54) CAN B BUS (-) CIRCUIT FOR AN OPEN Measure the resistance of the (D54) Can B Bus (-) circuit between the Front Control Module C1 harness connector and the Electronic Overhead Module harness connector. Is the resistance below 2.0 ohms? Yes Replace the Electronic Overhead Module in accordance with the service information. Perform BODY VERIFICATION TEST - VER 1. «(Refer to BODY VERIFICATION TEST - VER 1)»(ref-255944-S31737016002007060500000) . No Repair the Can B Bus (-) circuit for an open. Perform BODY VERIFICATION TEST - VER 1. «(Refer to BODY VERIFICATION TEST - VER 1)»(ref-255944-S31737016002007060500000) .
