Schematic diagram of the detonation sensorsTest Step 1. Inspect the Electrical Connectors and Wiring
Set the engine control to the OFF/RESET mode. Remove the electrical power from the engine.Note: For the following steps, refer to Troubleshooting, "Inspecting Electrical Connectors".
Thoroughly inspect each of the following connectors:
Connectors for the EIS control module
Connectors for each detonation sensor
J6/P6 connectors on the junction box (if equipped)

Harness side of the EISC connector (EISC-E) Signal from the right detonation sensor (EISC-H) Signal from the left detonation sensor (EISC-M) 13 VDC for the right detonation sensor (EISC-P) 13 VDC for the left detonation sensor (EISC-Y) Ground for the left detonation sensor (EISC-d) Ground for the right detonation sensor
Perform a 45 N (10 lb) pull test on each of the wires that are associated with the circuit for the detonation sensors.

Detonation sensor (1) Buffer module (2) Accelerometer (3) Wiring
Check the wiring (3) between each accelerometer (1) and each buffer module (2) for corrosion, for abrasion, and for pinch points.
Check the harnesses and the wiring for abrasion and for pinch points from each buffer module to the EIS control module.Expected Result:The connectors, pins, and sockets are connected properly. The connectors and the wiring do not have corrosion, abrasion, or pinch points.Results:
OK - The components are in good condition with proper connections. Proceed to Test Step 2.
Not OK - The components are not in good condition and/or at least one connection is improper.Repair: Perform the necessary repairs and/or replace parts, if necessary.STOPTest Step 2. Check for Diagnostic Codes
Connect the Digital Diagnostic Tool (DDT) to the service tool connector.
Restore the electrical power to the engine.
Clear any diagnostic codes.
Operate the engine under the conditions that caused the problem. Look for the diagnostic codes that are listed in Table 1.
Table 1
Diagnostic Codes for the Detonation Sensors    
318-01     Loss of Right Bank Detonation Sensor Signal    
318-03     Right Bank Detonation Sensor short to +batt    
318-05     Right Bank Detonation Sensor open or short to ground    
319-01     Loss of Left Bank Detonation Sensor Signal    
319-03     Left Bank Detonation Sensor short to +batt    
319-05     Left Bank Detonation Sensor open or short to ground    Expected Result:There are no diagnostic codes for the detonation sensors.Results:
OK - There are no diagnostic codes for the detonation sensors. The original problem seems to be resolved.Repair: If the engine is running properly at this time, there may be an intermittent problem in a harness that is causing the code to become activated. Refer to Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK (Active -01 Code) - The EIS control module has detected a low signal from a detonation sensor. Proceed to Test Step 3.
Not OK (Active -03 Code) - There is a -03 diagnostic code for a detonation sensor. Proceed to Test Step 7.
Not OK (Active -05 Code) - There is a -05 diagnostic code for a detonation sensor. Proceed to Test Step 11.Test Step 3. Check the Installation of the Detonation Sensor
Verify that the accelerometer is installed to the correct torque. Refer to Specifications, "Detonation Sensor".Expected Result:The accelerometer is installed correctly.Results:
OK - The accelerometer is installed correctly. Proceed to Test Step 4.
Not OK - The detonation sensor is installed incorrectly.Repair: Reinstall the detonation sensor. Verify that the original problem is resolved.STOPTest Step 4. Perform a Self Test of the EIS Control Module
Perform a self test of the EIS control module. Refer to Troubleshooting, "Control Module Self Test".Expected Result:The self test was successful.Results:
OK - The self test was successful. Proceed to Test Step 5.
Not OK - The self test was not successful.Repair: Perform the corrective action according to Troubleshooting, "Control Module Self Test". Verify that the original problem is resolved.STOPTest Step 5. Check for a Diagnostic Code
Operate the engine under the conditions that caused the original problem.Expected Result:There are no diagnostic codes.Results:
OK - There are no diagnostic codes. The problem appears to be resolved. The original problem was probably caused by a poor electrical connection.Repair: If the engine is running properly at this time, there may be an intermittent problem in a harness that is causing the code to become activated. Refer to Troubleshooting, "Inspecting Electrical Connectors".STOP
Not OK - The diagnostic code is still present. Proceed to Test Step 6.Test Step 6. Exchange the Detonation Sensors
Install the right detonation sensor into the position for the left detonation sensor. Install the left detonation sensor into the position for the right detonation sensor. Make sure that the detonation sensors are installed to the correct torque.
