Trunk - Closing Assist Modification

DATE: February 1994 (supersedes SI. MBNA 72/11, January 1994)

REF. NO.: 72/11A

SUBJECT: MODEL 140
MODIFIED TRUNK LID CLOSING ASSIST

Revision: Operation number in formation has been changed.






The trunk lid closing assist has been modified to include a "quick release which accelerates the extension of the striker (100. Figure 2), providing faster closing assist.

Effective Serial Number:
Model As of Chassis End Number
140 118121

Function:
The extension of the striker is no longer controlled by the closing assist supply pump but by the PSE control module. Therefore, the striker microswitch (S88/3) as well as some mechanical parts have been eliminated.

When the trunk lid is opened the closing assist striker is now extended by the PSE by means of pressurizing an additional element (2, Figure 2).

The retraction of the striker (when closing the trunk lid) is still performed by the closing assist supply pump.

Only the modified version with the quick release system will be available as a spare part.

The modified version may be installed in models prior to production phase-in. When installing the listed parts (see Parts Information), please note the following procedure:
1. Remove the trunk lid grip assembly and the trunk lid striker assembly (SMS, Job no. 88-530).
2. Make a bridge connector using a connector housing, part no. 012 545 84 28, and 2 contact pins. part no. 011 545 16 28, and insert it into the harness side connector of the striker microswitch (S88/3). which was deleted. Secure the harness to the existing wiring in the trunk lid with loom ties.
3. Transfer the element (10, Figure 1) from the old striker assembly to the new striker assembly (SMS, Job no. 88-540).
4. Install the new element part no. 202 800 20 75 (2, Figure 2) on to the new striker assembly. Connect the rod, part no. 140 758 03 23, (7, Figure 2) to the striker assembly with the lock clip, part no. 140 758 00 83. (6, Figure 2) as shown in Figure 2.
5. Connect the red vacuum line to the element (10, Figure 2) and reinstall the trunk striker assembly. Connect the short line, part no. 140 800 58 81. (4, Figure 2) to the 3-way connector. part no. 202 800 03 22 (3, Figure 2). Connect the 3-way connector to the element (2, Figure 2).
6. Connect the other end of the short black line to the trunk lid grip assembly (11, Figure 4).
7. Connect the new longer black vacuum line. part no. 140 800 57 81. (5. Figure 2) to the 3-way connector on the trunk striker assembly and route it above the trunk lid grip assembly. Trimming if necessary, splice the new vacuum line to the old vacuum line (previously connected the trunk lid grip assembly) using a short piece of vacuum hose, part no. 007 997 61 82 (8, Figure 4).
8. Adjust trunk latch and striker as required (SMS Job no. 88-502. steps 10-13).

Future production phase-in of the modified closing assist supply pump part nos. 140 800 16 48 or 140 800 17 48 will eliminate the need for the connector, part # 012 545 84 28, and the pins pan no. 011 545 16 28.
