-
Are the voltages greater than 10 volts?
Yes
GO to C7.
No
VERIFY the Smart Junction Box (SJB) fuse 26 (10A) or 29 (5A) is OK. If OK, REPAIR the circuit in question. If not OK, Refer to the Wiring
Diagrams to identify the possible causes of the short circuit. CLEAR the DTCs. REPEAT the network test with the scan tool. See: Diagrams/Electrical
Diagrams/Diagrams By Number
-------------------------------------------------
C7 CHECK FOR CORRECT IC OPERATION
-
Disconnect the IC connector.
-
Check for:
-
corrosion
-
damaged pins
-
pushed-out pins
-
Connect the IC connector and make sure it seats correctly.
-
Operate the system and verify the concern is still present.
-
Is the concern still present?
Yes
INSTALL a new IC. REFER to Instrument Panel, Gauges and Warning Indicators. CLEAR the DTCs. REPEAT the network test with the scan tool.
No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
