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
|
|
