PROCEDURE
1. |
CHECK FOR SHORT IN CAN BUS LINES (CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU)) |
(a) Disconnect the cable from the negative (-) battery terminal.
(b) Disconnect the central gateway ECU (network gateway ECU).
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
OK | ![]() |
REPLACE CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU) |
|
2. |
CHECK FOR SHORT IN CAN BUS LINES (ECM - CENTRAL GATEWAY ECU (NETWORK GATEWAY ECU)) |
(a) Disconnect the A38 ECM connector.
(b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
OK | ![]() |
REPLACE ECM
