I have a U1262 (SCP) Data Link Fault and C1284 Oil Pressure Switch Failure. These codes existed since May 29th. My Mustang is stock except for the cold air intake which was installed in 2012 and also added Reverse Glow Gauge which now needs to be replaced since its not glowing anymore. Any help is appreciated. Repair report below.
C1284 Code Definition
Oil Pressure Switch Failure\nNote: This code may not be valid. Re-run the Self-Test with the vehicle running to verify the code.
*3 Frequently Reported Fixes
-Replaced Fuel Pump w/U1043
-Replaced Fuse #34 w/B1681, U1043, U1262
-Replaced Fuse(s) w/B1681, U1043, U1262 (In progress - Replacing all)
U1262 Code Definition
SCP Communication Bus Fault - Perform Network Communications Test
*2 Possible Causes
-Invalid Data: Data transferred in normal inter-module messages with know invalid data. Transmitting module will set the code.
-Missing Network Data: Missing messages fault logged by a module upon failure to receive a message from another module within a defined retry period.
