PROCEDURE
1. |
CHECK FOR OPEN IN CAN MAIN BUS LINES (NO. 3 CAN JUNCTION CONNECTOR) |
(a) Disconnect the cable from the negative (-) battery terminal.
(b) Disconnect the No. 3 CAN junction connector.
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
OK |
REPLACE NO. 3 CAN JUNCTION CONNECTOR |
|
2. |
CHECK FOR OPEN IN CAN MAIN BUS LINES (CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU) - NO. 3 CAN JUNCTION CONNECTOR) |
(a) Reconnect the F114 No. 3 CAN junction connector.
(b) Disconnect the central gateway ECU (network gateway ECU) connector.
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
OK |
REPLACE CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU) |
NG |
REPAIR OR REPLACE CAN MAIN BUS LINES OR CONNECTOR (CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU) - NO. 3 CAN JUNCTION CONNECTOR) |
