ECM will log a diagnostic code and a
warning will appear on the messenger
while the diagnostic code is Active.

Always inspect the harness connectorsthat are involved in the circuit.
Poor connections can often be the cause of a problem in an electrical
circuit. Verify that all connections in the circuit are clean and secure,
and that all connections are in good condition. If a problem with a
connection is found, correct the problem and verify that this diagnostic
code is Active before performing this procedure.
Perform open or short circuit test ateach harness connection to identify
correct harness to replace.
Perform this test only if condition is Active.
Test Step 1. Check for Other Codes.
1. Connect MSD (WP 0006). Select
Trans/chassis 120M and verify
1403-13 is active.
Only Code 1403-13 Active - Proceed
2. Check for Active code 1403-03,
to Test Step 2.
1403-05, or 1403-06 in Trans/
chassis 120M (WP 0006).
Code 1403-03, 1403-05, or 1403-06
Active - Troubleshoot lower code first
before proceeding.
