DIAGNOSTIC CODE 3-5 (ADVANCED) Test 37
Test 42
Checking for wrong target, bad data file or V-MAC II module
Checking for a blocked oil drain holes and filters
1. Use the diagnostic tool (Pro-Link or PC) to display the engine model, data file part number and static timing. 2. Verify the following information: a. The engine model listed on the emissions plate agrees with the engine model displayed in V-MAC II. b. Initial (static) timing on the emissions plate agrees with the value displayed in V-MAC II. c. ECONOVANCE is approximately 5 inches long.
If the information matches but the timing is still too advanced, replace the V-MAC II module. Retest to be sure the problem has been corrected. If the information does not match, V-MAC II is trying to use a data file which may not match the engine hardware’s capabilities (static timing and timing range). Change the hardware to match the hardware requirements of the data file and attach the proper emissions plate, or download the correct data file for this engine. Retest to be sure the problem has been corrected.
Figure 156 — Timing Control Valve Drain Holes and Filters
1. Check the ECONOVANCE drain hole for blockage. Clean if needed. 2. Check the ECONOVANCE oil supply hole for blockage. Clean if needed. 3. Remove the secondary filter in the timing control valve body if equipped. Check the passage in the valve body for blockage. Clean the secondary filter if needed. Reinstall the secondary filter. 4. Clean the valve oil supply filter. Correctly install a new gasket. Reinstall the timing control valve. Retest to be sure the problem has been corrected. If the timing is still too advanced, replace the timing control valve and gasket.
If this test is being conducted at high idle, retest with the new timing valve. If after retesting, the timing is still too advanced after the timing valve has been replaced, the ECONOVANCE seals should be replaced. The original timing control valve was not defective and should be reinstalled. Refer to the E7 Engine Service Manual for instructions on how to replace the ECONOVANCE seals. Page 101
