Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

READ VALUE OF TECHSTREAM (CRUISE CONTROL MAIN SWITCH)

Connect the Techstream to the DLC3.
Turn ignition switch to the ON position.
Turn the Techstream on.
Enter the following menus: Powertrain / Cruise Control / Data List.
Check the Data List for proper functioning of the cruise control main switch.

Item	Measurement Item / Display (Range)	Normal Condition	Diagnostic Note
CCS Main SW M-CPU	Main switch Signal (Main CPU) / ON or OFF	ON: Main switch on OFF: Main switch off	-
Cancel Switch	CANCEL switch signal/ON or OFF	ON: CANCEL switch on OFF: CANCEL switch off	-
SET/COAST Switch	- (COAST)/SET switch signal/ ON or OFF	ON: - (COAST)/ SET switch on OFF: - (COAST)/ SET switch off	-
RES/ACC Switch	+ (ACCEL)/RES switch signal/ON or OFF	ON: + (ACCEL)/RES switch on OFF: + (ACCEL)/RES switch off	-

OK: When cruise control switch operation is performed, the results will be same as above.

OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

NG: GO TO NEXT STEP.

INSPECT CRUISE CONTROL MAIN SWITCH

Disconnect the cruise control switch connector.

Measure the resistance of the switch.

Standard resistance

CRUISE CONTROL MAIN SWITCH

Tester Connection	Switch Condition	Specified Condition
3 - 4	cruise control switch ON	10 kΩ or higher
	cruise control switch OFF	Below 1 Ω
	+/RES	216 to 264 Ω
	-/SET	567 to 693 Ω
	CANCEL	1,386 to 1,694 Ω

NG: REPLACE CRUISE CONTROL MAIN SWITCH

OK: GO TO NEXT STEP.

INSPECT SPIRAL CABLE

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. Be sure to read the pages referenced.

HINT:

Removal (See REMOVAL ).
Installation (See INSTALLATION ).

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

Standard resistance

SPIRAL CABLE

Tester Connection	Spiral Cable Position	Specified Condition
A-3 (CCS) - E7-1 (CCS)	Center	Below 1 Ω
	2.5 rotations to the left
	2.5 rotations to the right
A-4 (ECC) - E7-2 (ECC)	Center
	2.5 rotations to the left
	2.5 rotations to the left

HINT:

The spiral cable makes a maximum of approximately 5 rotations.

NG: REPLACE SPIRAL CABLE SUB-ASSEMBLY

OK: Go TO NEXT STEP.

CHECK WIRE HARNESS (SPIRAL CABLE - ECM AND BODY GROUND)

Disconnect the E7 cable connector.
Disconnect the A9 ECM connector.

Measure the resistance of the wire harness side connectors.

Fig 4: Checking Wire Harness (Spiral Cable - ECM And Body Ground)

Standard resistance

SPIRAL CABLE - ECM AND BODY GROUND

Tester Connection	Specified Condition
E7-1 (CCS) - A9-40 (CCS)	Below 1 Ω
E7-2 (ECC) - Body ground	Below 1 Ω

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
