The first step to replace the Air Bag Sensor Rear LH demands implementing restraint systems service precautions followed by removing the battery negative terminal. Start by taking out the Deck Board No.1 followed by Deck Trim Cover Rear and next remove the Rear Door Scuff Plate LH, Rear Door Opening Trim Weather Strip LH, Rear Seat Cushion W/Cover Pad Sub-Assy, Rear Seat Back Assy LH, and finally the Rear Seat Back Hinge Sub-Assy LH and Rear Seat 3 Point Type Belt Assy Outer. First disconnect the connector from the Air Bag Sensor Rear LH and remove its bolt before taking out both the Air Bag Sensor Rear LH and the Deck Trim Side Panel Assy LH. Begin the installation of the new Air Bag Sensor Rear LH only after disconnecting the battery negative terminal for 90 seconds when the ignition switch stands off. Secure the sensor with its bolt while applying 9.0 Nm of torque which equals 92 kgf.cm and 80 in.lbf. The sensor needs replacement with a new part when drops or evidence of cracks and dents and defective components become present. The SRS wiring must be kept away from any other installed components which could cause pinching or wire interference. Use the sensor connector then inspect all installing parts for potential looseness. Inspection of the SRS warning light completes the procedure for installing the Rear Seat Back Hinge Sub-Assy LH together with Rear Seat Back Assy LH.

Repairing the Air Bag Sensor Assy Center requires two prerequisites which include following restraint systems service cautions and disconnecting the battery negative terminal. The instrument panel finish panel lower center needs removal before you can take out the Air Bag sensor assy center by following three connector removal steps together with torx socket wrench (T40) usage for 4 torx screw removal. Establishing installation of the new Air Bag sensor assy center requires an off switch on the ignition and a disconnected negative battery terminal with at least 90 seconds until proceeding. The torx socket wrench (T40) should be used to install the Air Bag sensor assy center using 4 torx screws until they reach 20 Nm (200 kgf.cm, 14 ft.lbf) torque. The Air Bag sensor assy center requires replacement when it experiences either falls or reveals damage through cracks or dents or shows any signs of defect. During installation make sure the SRS wires avoid other components and stay free from any pinching. The connectors should be connected to the Air Bag sensor assy center followed by a check for loose installation parts and confirmation of proper water-proof sheet placement. One should check the SRS warning light as the last step.

When replacing the Air Bag Sensor Front RH you need to begin by observing restraint systems service precautions then disconnecting the battery negative terminal. Users should remove the Air Bag front RH sensor through two bolt removal and connector separation steps. Begin installing the new Air Bag front RH sensor after turning off the ignition switch and disconnecting the battery negative terminal. Keep waiting at least 90 seconds after disconnecting before starting installation. Affix the new front RH air bag sensor with its 2 bolts and torque them to 17.5 Nm (178 kgf.cm, 13 ft.lbf). You need to replace the Air Bag front RH sensor whenever there are signs of falling or cracking or denting or imperfect condition. Take care to inspect that SRS wiring cables avoid contact with other vehicle components when installing the system. Inspect for installation part looseness after you attach the sensor connector. Conclude the inspection by checking if the SRS warning light operates correctly.

The first step for replacing the Air Bag Sensor Front LH includes observation of restraint systems service precautions and disconnection of the battery negative terminal. Remove the bolt from the air cleaner inlet assembly and disconnect the connector from the Air Bag sensor front LH while removing its two securing bolts. The process of installation requires waiting for at least 90 seconds after disconnecting the negative terminal while the ignition switch remains off. Place the Air Bag sensor front LH in position using the two bolts which should be tightened to 17.5 Nm (178 kgf.cm, 13 ft.lbf). Any Air Bag sensor front LH must be replaced with a new one if the device has suffered falling damage or reveals broken or deformed parts. SRS wiring should be kept free from any contact that might arise while installing the system. The Air Bag sensor front LH connector should be connected and the installation should be checked for any loose components. The reinstall process starts with tightening the air cleaner inlet assembly bolt to 7.5 Nm (76 kgf.cm, 66 in.lbf). A check of SRS warning light operation must occur.

The first step for replacing the Air Bag Sensor Assy Center involves battery terminal disconnection and safety precautions. The first step includes removing the Console Upper Rear Panel Sub-Assy together with the Console Panel Sub-Assy Upper followed by Console Upper Panel Garnish No.1, Console Upper Panel Garnish No.2, Console Box Assy Rear, Console Box Mounting Bracket Front and Console Box Duct No.1. Proceed by detaching three connectors from the Air Bag Sensor Assy Center then remove its three securing bolts. The sensor replacement procedure requires turning the ignition switch to OFF position and maintaining the battery terminal disconnected for 90 seconds until beginning the operation. First tightly secure the Air Bag Sensor Assy Center with 3 bolts that will temporarily stay in place before torquing them to 17.5 N.m (178 kgf.cm, 13 ft.lbf). Attach connectors properly to the Air Bag Sensor Assy Center without any movement while maintaining the right position of the waterproof sheet. The last step should involve examining the SRS warning light.

Start replacing the Air Bag Sensor Assembly after disconnecting the battery negative terminal while taking proper safety measures. Start by removing the console panel upper rear and console box carpet as well as the rear console box and instrument panel cup holder tray without ashtray and the instrument panel ash receptacle assembly with ashtray. Proceed then by removing the console panel upper followed by the console box front along with air duct rear No.1 and No.2 and Console box duct No.1 specifically for auto air conditioner systems. Unplug the three connectors from the air bag sensor assembly center before removing its three retaining bolts. Testing of the air bag sensor assembly center must be completed before reinstall. After removal of the battery negative terminal you should wait 90 seconds with the ignition switch off. Secure the air bag sensor assembly center to its installation position using temporary 3 bolts until they reach 17.5 N.m (178 kgf.cm, 13 ft.lbf) torque value. Connect the connector to the air bag sensor assembly center and check for proper water-proof sheet placement without any loose fitting. Before closing the check execute an inspection of the SRS warning light operation.

The procedure to replace the Side Air Bag Sensor Assy RH starts with disconnecting the negative battery terminal and waiting for at least 90 seconds before commencing work. Begin by taking away the front door scuff plate RH followed by the rear door scuff plate RH and the front door opening trim Weather Strip RH along with the rear door opening trim Weather Strip RH and center pillar garnish lower RH. To replace the side air bag sensor assembly RH begin by removing the front seat outer belt assembly RH and followed by disconnecting its connector and removing the 3 bolts from the sensor assembly RH. The procedure for installing the new side air bag sensor assembly RH demands a completely disconnected battery along with a turned-off ignition switch prior to beginning. Before completing the assembly installation secure it with three bolts where the torque should reach 20 Nm (204 kgf.cm, 15 ft.lbf). A side air bag sensor assembly replacement is necessary when the assembly suffers from drops or when any damage becomes visible. Ensure that all SRS wiring stays safe from both interference and pinch when setting up the system. Use the connector to reattach it to the side air bag sensor assembly RH and inspect the installation parts for looseness before checking the SRS warning light status.

Ensure the sensor assembly is free from defects and that the SRS wiring does not interfere with other components. Check for any looseness by shaking the sensor assembly.

Ensure the ignition switch is off and the battery negative terminal is disconnected, waiting at least 90 seconds after removal.
