2008 Toyota Camry XLE, 2.4 ESECTION Inspection Procedure

NOTE: The vehicle is equipped with an SRS (Supplemental Restraint System) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the precautionary notice for the supplemental restraint system (See PRECAUTION ).

CHECK ILLUMINATION

Check if the illumination for the radio receiver, steering pad switch, glove box or others (hazard switch, transmission control switch, etc.) comes on when the light control switch is turned to the HEAD or TAIL position.

Measure the voltage according to the value(s) in the table below.
Standard voltage

BATTERY - SPIRAL CABLE

Tester connection	Condition	Specified condition
IL+2 - Body ground	Light control SW TAIL or HEAD	10 to 14 V

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

OK: Go To Next Step

INSPECT STEERING PAD SWITCH ASSEMBLY
1. Disconnect the steering pad switch connector.

2. Connect the positive (+) lead to terminal IL+2 and the negative (-) lead to terminal EAU of the steering pad switch assembly connector.
3. Check if the illumination for the steering pad switch assembly comes on.
  OK: Illumination for the steering pad switch assembly comes on.
  
  NG: REPLACE STEERING PAD SWITCH ASSEMBLY
  
  OK: Go To Next Step

INSPECT SPIRAL CABLE

Disconnect the steering pad switch and spiral cable connectors.

Measure the resistance according to the value(s) in the table below.
Standard resistance

SPIRAL CABLE

Tester connection	Spiral cable position	Specified condition
EAU - EAU	Center	Below 1 Ω
	2.5 rotations to the left
	2.5 rotations to the right
IL+2 - IL+2	Center	Below 1 Ω
	2.5 rotations to the left
	2.5 rotations to the right

NOTE: The spiral cable is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable may prevent the airbag from deploying.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
