Hello .. thanks for the donation ..much appreciated

Pull off the battery terminals for 5 minutes then reconnect(have your radio code handy) .. this should delete the code from memory .. if not perform the following test's ..you will have to perform a computer relearn drive cycle after this .. drive vehicle in normal stop and go traffic and a highway trip at regular speeds for 15 minutes !! no repeat donation is necassary .. I will forward your message to our administrators if you require .. ??

Hope this helps ..let me know

TEST QB: KOEO DTC P0603, P1605 OR KOEO, KOER & CONTINUOUS MEMORY DTC P1633
NOTE:After each service or repair procedure has been completed, reconnect all components. Clear DTCs and repeat QUICK TEST procedures to ensure all EEC-V systems are working properly and DTCs are no longer present.

Perform this test when instructed during QUICK TEST or if directed by other test procedures. This test is used to diagnose the following:
Battery Terminal Condition
Keep Alive Power (KAPWR) Circuit Routing
KAPWR Circuit Condition
Faulty Powertrain Control Module (PCM)
1) Check Battery Terminals

Inspect battery terminals for corrosion or loose connection. Service as necessary. If battery terminals are okay, go to next step.
2) Check Engine Compartment Wiring Harness For Proper Routing

Inspect wiring harness and connectors for damage or corrosion. Ensure wiring harness is properly routed and not too close to ignition or exhaust components. Service as necessary. If no problems are found, go to next step.
3) Check Keep Alive Power Circuit To PCM

Turn ignition switch to OFF position. Disconnect PCM connector(s). Inspect connector for loose, damaged or corroded terminals. Repair as necessary. Using a DVOM, measure voltage of KAPWR circuit between ground and PCM harness connector terminal No. A44 (LS), or terminal No. 55 (all other models). While observing DVOM, wiggle and bend small sections of wiring harness between PCM and dash panel. If voltage is continuously 10.5 volts or more, go to next step. If at anytime voltage drops to less than 10.5 volts, isolate open in KAPWR circuit and repair as necessary.
4) Check For Repeat Of DTC P0603, P1605 Or P1633

Reconnect PCM connector(s). Start engine and allow to idle and reach normal operating temperature. Perform KOEO ON-DEMAND SELF-TEST. Retrieve Continuous Memory DTCs. If DTC P0603, P1605 or P1633 is present, replace PCM. If any other DTCs are present, service as necessary. See DIAGNOSTIC TROUBLE CODE DEFINITIONS table. If no DTCs are present, testing is complete. DTC P0603, P1605 or P1633 may have been due to a previous repair.
