-
If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring and voltage supply was OK:
-
Replace the Secondary Air Injection (AIR) Pump Relay J299.
-
Erase the DTC memory. See: Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 -
Erase DTC Memory
-
Perform a road test to verify repair.
If the DTC does not return:
-
Generate readiness code. See: Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
If the DTC returns and no malfunction is found in the wiring and the voltage supply was OK:
-
Replace the Engine Control Module (ECM) J623.
Final procedures
After repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03 -
Read DTC Memory
2. If necessary, erase the DTC memory. See: Computers and Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic
Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. See: Computers and Control Systems/Testing and Inspection/Monitors, Trips, Drive
Cycles and Readiness Codes
