WARNING: This page is about a different car, the 2002 Pontiac Firebird and 2002 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

DTC cannot be retrieved with a current status. Diagnosis of U1300 is accomplished by diagnosing by symptom. An intermittent condition is likely to be caused by a short to ground on class 2 serial data circuit. Perform TEST B: SCAN TOOL DOES NOT COMMUNICATE WITH CLASS 2 DEVICE  under SYSTEM TESTS.
