KEYLESS RECEIVER INSPECTION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM]

id0914005144z3


L.H.D.

1.  Remove the following parts:

(1)  Front scuff plate (LH) (See FRONT SCUFF PLATE REMOVAL/INSTALLATION.)
(2)  Front side trim (LH) (See FRONT SIDE TRIM REMOVAL/INSTALLATION.)
(3)  Upper panel (See UPPER PANEL REMOVAL/INSTALLATION.)
(4)  Shift knob (MTX) (See MANUAL TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
(5)  Selector lever knob (ATX) (See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
(6)  Shift panel (See SHIFT PANEL REMOVAL/INSTALLATION.)
(7)  Side wall (See SIDE WALL REMOVAL/INSTALLATION.)
(8)  Console (See CONSOLE REMOVAL/INSTALLATION.)

2.  Set the bonnet release lever out of the way. (See BONNET LATCH AND RELEASE LEVER REMOVAL/INSTALLATION.)

3.  Remove the lower panel. (driver-side) (See LOWER PANEL REMOVAL/INSTALLATION.)

4.  Remove the keyless receiver with the connector connected.

5.   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 parts or related wiring harnesses do not have any malfunction, replace the keyless receiver.

6.  Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [MZR 1.5, MZR 1.6].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0, MZR 2.5].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.0 DISI i-stop].) (See BATTERY REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].) (See BATTERY REMOVAL/INSTALLATION [MZR-CD 2.2].)
