Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

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 AIRBAG SYSTEM ).

INSPECT RADIO RECEIVER

Disconnect the radio receiver connector R2 (1), R6 (2).

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

Standard resistance

STANDARD RESISTANCE SPECIFICATION

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
AU1-AU1	Center	Below 1 Ω
	2.5 rotations to the left
	2.5 rotations to the right
