SERVICE FIX VIM Amplifier Deletion Engine DTC P2008 set VE & WM – All with V6 Group 6C Ref. No. TL1218 – 0702 BACKGROUND A VIM (Variable Intake Manifold) amplifier is fitted to early VE & WM V6 vehicles to amplify signals between the VIM (or IMRC - Intake Manifold Runner Control) and the ECM. The VIM amplifier is connected (by wiring) between the VIM valve on the rear of the intake manifold and the ECM. The VIM amplifier is to be deleted from vehicle production as detailed below, and the VIM valve will then be connected directly to the ECM, as a result of software and hardware improvements. All software released via TIS 2000 from now on will not support VIM Amplifiers, as this would mean creating dual software calibrations and would cause extended delays in calibration validation. REVISION – Vehicle Production VIM amplifiers have been deleted from vehicle in production from: LY7 A/T Engines: (V6 Premium) ISOVIN: Built Date: L924443 20/02/07 LY7 M/T Engines: (V6 Premium) ISOVIN: Built Date: L926102 23/02/07 LE0 A/T Engines: (V6 Base) ISOVIN: Built Date: 6G1EKS2897L902727 15/12/06 LW2 A/T Engines: (V6 LPG) ISOVIN: Built Date: 6G1EKS2N27L913482 22/01/07 SERVICE PROCEDURE The Service Procedure detailed below will be required ONLY if one of the following conditions occurs. A. The ECM is re-programmed (SPS) using TIS 76.0 or later, and the vehicle is fitted with a VIM amplifier module; B. “Ensure VIM Amp Rework is Completed” is displayed in TIS when performing SPS programming. C. The ECM is replaced and the vehicle is fitted with a VIM amplifier module (“Ensure VIM Amp Rework is Completed” will be displayed on Tech-2); NOTE: Not carrying out the following procedure when one of the above conditions (A, B or C) occurs, will result in customer complaints due to unnecessary DTC setting (DTC P2008) and CEL displaying. Procedure 1. At the RH side of the engine compartment, remove the larger connector - J1 (X1) from the Engine Control Module (ECM). As per Figure 1, fully rotate the handle, use a marker to mark the “fully open” position of the rack and connector as shown (to allow easy refitting). Remove the handle by lining up the notches and levering with a flat head screw driver. Figure 1. 2. Remove the rack from the connector, as shown in Figure 2: Figure 2 3. Remove the outer case by levering each of the corners of the connector with a flat head screw driver, as shown in Figure 3: Figure 3. 4. Remove the terminal locking key by sliding a flat head screw driver underneath the top of the key and levering upwards as in Figure 4: Mark rack & connector when handle is fully clockwise Align “notches”
