There is the message on the instrument panel, “When Parked Apply Parking Brake”,
And
DTC P189A (Motor “A” Circuit Low) is stored as current and will not erase,
And
Terminal 1 and/or terminal 2, inside connector E54, are loose. See Figure 2 on the next

3.

Use Spread Terminal Gauge J-48817-28, from the Terminal Repair Kit, to inspect
terminals 1 and 2 for the correct pin fit as follows:

IMPORTANT: For the following steps (3a-3d)
 Good Terminal – The Spread Terminal Gauge should compress completely without
sliding into the terminal. If it compresses completely, DO NOT insert it.
 NG Terminal – The Spread Terminal Gauge will not compress or will only partially
compress before sliding into the terminal.

# J-48817-28

a. Align the tip of the Spread
Terminal Gauge (Figure 3) so that
it is offset to one side (see Figure 4
and Figure 5).
NOTE: The Spread Terminal
Gauge will be used twice on each
terminal.
b. Gently attempt to insert the Spread
Terminal Gauge into the selected
terminal while observing if it
compresses. DO NOT insert the
gauge into the terminal if it
compresses completely.

c. Relocate the Spread Terminal Gauge to the opposite side of the same terminal
(see Figure 4 and Figure 5 and repeat step 3b. DO NOT insert the gauge into
the terminal if it compresses completely.
d. Repeat steps 3a-3c on the second terminal.
Example only: Terminal removed to allow clear view of pin test

 Does the Spread Terminal Gauge compress completely without sliding into any of
the test points (total of 4 test points)?


YES: The terminals have the correct pin fit. Refer to the Electronic Service
Manual (ESM) for further diagnostics not covered under this bulletin.



NO: Proceed to step 4.

Pull harness connector E54 straight up
and out of the relay box.

Figure 7

For the following repair the entire motor room harness will not be used. Only the
Parking Actuator Relay “A” harness connector (E54) will be removed from it to repair
the pre-existing harness.

10.

Repeat steps 7-9 on E54 of the new
motor room harness.

Cut all four (4) wires of the new E54 harness connector, and then remove it from the
new motor room harness relay box.


Cut wires so that they are as long as possible; approximately 4-5 inches.

Cut all four (4)
wires here.

12.

Strip approximately 10 mm of insulation from the ends of each wire (see Figure 10).

IMPORTANT: In the following steps the old harness connector wires (still in vehicle) will be
cut, striped, and soldered together, one at a time. Two wires are the same color, but of a
slightly different gauge wire (see Figure 10).

These two blue wires are the same
color, but are different gauges

The solder sleeve connectors are
listed in the Parts Information
section of this bulletin on page 13.
