Title: CRUISE CONTROL: CRUISE CONTROL MAIN SWITCH: INSPECTION (2008 LX570)

INSPECTION

1. INSPECT CRUISE CONTROL MAIN SWITCH ASSEMBLY

(a) Measure the resistance (for vehicles without vehicle-to-vehicle distance control mode).



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

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

1 (ECC) - 3 (CCS)

Neutral

1 MΩ or higher

1 (ECC) - 3 (CCS)

+RES

235 to 245 Ω

1 (ECC) - 3 (CCS)

-SET

620 to 640 Ω

1 (ECC) - 3 (CCS)

CANCEL

1510 to 1570 Ω

1 (ECC) - 3 (CCS)

Main switch off

1 MΩ or higher

1 (ECC) - 3 (CCS)

Main switch on

Below 2.5 Ω

If the result is not as specified, replace the cruise control main switch assembly.

(b) Measure the resistance (for vehicles with vehicle-to-vehicle distance control mode).



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

Standard Resistance:

Tester Connection

Switch Condition

Specified Condition

1 (ECC) - 2 (R/N)

1 (ECC) - 3 (CCS)

Neutral

1 MΩ or higher

1 (ECC) - 3 (CCS)

+RES

235 to 245 Ω

1 (ECC) - 3 (CCS)

-SET

620 to 640 Ω

1 (ECC) - 3 (CCS)

CANCEL

1510 to 1570 Ω

1 (ECC) - 3 (CCS)

Main switch off

1 MΩ or higher

1 (ECC) - 3 (CCS)

Main switch on

Below 2.5 Ω

3 (CCS) - 2 (R/N)

Main switch on and mode switch on

Below 2.5 Ω

If the result is not as specified, replace the cruise control main switch assembly.
