PINPOINT TEST G831824p9 : SPEED CONTROL SWITCH CIRCUIT TESTS
G831824t29 : CHECK THE STEERING WHEEL SPEED CONTROL SWITCH FOR OPEN CIRCUIT
1. Disconnect the battery negative terminal.
2. Wait two minutes for the system to become safe.
3. Disconnect the speed control switch connector SW009.
4. Measure the resistance between:
speed control switch connector SW009, pin 02, component side
speed control switch connector SW009, pin 03, component side
-
Is the resistance 4310 ohms?
->YES
GO to Pinpoint Test G831824t23.
->NO
INSTALL a new speed control switch assembly. TEST the system for normal operation.
G831824t23 : CHECK THE STEERING WHEEL SPEED CONTROL RESUME SWITCH CIRCUIT
1. Measure the resistance between:
speed control switch connector SW009, pin 02, component side
speed control switch connector SW009, pin 03, component side
2. Operate the RESUME switch.
-
Does the resistance switch between 4310 ohms and 2110 ohms when the switch is operated?
->Yes
GO to Pinpoint Test G831824t24.
->No
INSTALL a new speed control switch assembly. TEST the system for normal operation.
G831824t24 : CHECK THE STEERING WHEEL SPEED CONTROL SET+ SWITCH CIRCUIT
1. Measure the resistance between:
speed control switch connector SW009, pin 02, component side
speed control switch connector SW009, pin 03, component side
2. Operate the SET+ switch.
-
Does the resistance switch between 4310 ohms and 1110 ohms when the switch is operated?
->YES
GO to Pinpoint Test G831824t25.
->NO
INSTALL a new speed control switch assembly. TEST the system for normal operation.
G831824t25 : CHECK THE STEERING WHEEL SPEED CONTROL HEADWAY REDUCTION SWITCH CIRCUIT
1. Measure the resistance between:
speed control switch connector SW009, pin 02, component side
speed control switch connector SW009, pin 03, component side
2. Operate the HEADWAY REDUCTION switch.
-
