1. Remove the following parts:

(1) Front scuff plate (driver's side)(5HB) (See FRONT SCUFF PLATE REMOVAL/INSTALLATION.)

(2) Front scuff plate (driver's side)(3HB) (See FRONT SCUFF PLATE REMOVAL/INSTALLATION [3HB].)

(3) Rear console (L.H.D.)(See REAR CONSOLE REMOVAL/INSTALLATION.)

(4) Shift lever knob (See MANUAL TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION [F35M-R].)(See MANUAL TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION [B65M-R].)

(5) Side wall (See SIDE WALL REMOVAL/INSTALLATION.)

(6) Front console component (See FRONT CONSOLE COMPONENT REMOVAL/INSTALLATION.)

(7) Bonnet release lever (See BONNET LATCH AND RELEASE LEVER REMOVAL/INSTALLATION.)

(8) Lower panel (See LOWER PANEL REMOVAL/INSTALLATION.)

2. Measure the voltage according to the terminal voltage table.

• If the voltages cannot be verified as indicated in the terminal voltage table, inspect the parts under “Inspection item(s)”.

― If the system does not work normally even though the inspection items or related wiring harnesses do not have any malfunction, replace the theft-deterrent control module.

Pattern 1

am2zzw00005204

• Oscilloscope setting: 1 V/DIV (Y): 1 ms/DIV (X), DC range

Pattern 2

Note

• A solid line indicates the theft-deterrent control module output wave pattern, and a dotted line indicates the BCM output wave pattern. Because the theft-deterrent control module is wired to the BCM, the wave pattern output from each overlaps on the oscilloscope screen.

• In addition, if the theft-deterrent control module wave pattern cannot be verified by a constantly changing overlapped wave pattern, because the output wave pattern intervals for the two modules differs, it is necessary to wait for a while and then verify wave pattern.

• Oscilloscope setting: 2 V/DIV (Y): 1 ms/DIV (X), DC range

Pattern 3

am2zzw00005206

• Oscilloscope setting: 1 V/DIV (Y): 5 ms/DIV (X), DC range

Pattern 4

Note

• Because theft-deterrent control module terminal X is connected to the BCM terminal 6Q, the wave pattern output from the BCM is displayed. The wave pattern in the figure is the BCM output wave pattern, and the voltage/wave pattern for theft-deterrent control module terminal X is not output. If there is any abnormality in the wave pattern, inspect the BCM and the related wiring harness.
