: DTC P0568: SPEED CONTROL INPUT SIGNAL LOW/HIGH RESISTANCE

G240073t9 : CHECK THE INTERNAL STEERING WHEEL CIRCUIT FOR HIGH RESISTANCE, RESUME SWITCH CIRCUIT
1. Disconnect the battery negative terminal.
2. Wait one minute for the system to become safe.
3. Disconnect the steering wheel switch electrical connector.
4. Measure the resistance between pins 01 and 03 of the speed control switch.
5. Operate the RESUME switch.

- Does the resistance switch between 4300 and 2100 ohms as the switch is operated?

-> Yes

-> No
INSTALL a new speed control switch assembly. CLEAR the DTC. TEST the system for normal operation.

G240073t10 : CHECK THE INTERNAL STEERING WHEEL CIRCUIT FOR HIGH RESISTANCE, CANCEL SWITCH CIRCUIT
1. Operate the CANCEL switch.

- Does the resistance switch between 4300 and zero ohms as the switch is operated?

-> Yes

-> No
INSTALL a new speed control switch assembly. CLEAR the DTC. TEST the system for normal operation.

G240073t11 : CHECK THE INTERNAL STEERING WHEEL CIRCUIT FOR HIGH RESISTANCE, SET/+ SWITCH CIRCUIT
1. Operate the SET/+ switch.

- Does the resistance switch between 4300 and 1100 ohms as the switch is operated?

-> Yes

-> No
INSTALL a new speed control switch assembly. CLEAR the DTC. TEST the system for normal operation.

G240073t12 : CHECK THE INTERNAL STEERING WHEEL CIRCUIT FOR HIGH RESISTANCE,SET/ - SWITCH CIRCUIT
1. Operate the SET/- switch.

- Does the resistance switch between 4300 and 120 ohms as the switch is operated?

-> Yes

-> No
INSTALL a new speed control switch assembly. CLEAR the DTC. TEST the system for normal operation.

G240073t13 : CHECK THE STEERING WHEEL CLOCKSPRING FOR HIGH RESISTANCE
1. Disconnect the clockspring electrical connector, SW08.
2. Measure the resistance between SW08, pin 06 and the steering wheel switch electrical connector, pin 03 (S).

- Is the resistance greater than 5 ohms?

-> Yes
INSTALL a new clockspring. CLEAR the DTC. TEST the system for normal operation.

-> No

G240073t3 : CHECK THE STEERING WHEEL CLOCKSPRING FOR HIGH RESISTANCE
1. Measure the resistance between SW08, pin 08 and the steering wheel switch electrical connector, pin 01 (SR).

- Is the resistance greater than 5 ohms?

-> Yes
INSTALL a new clockspring. CLEAR the DTC. TEST the system for normal operation.

-> No

G240073t14 : CHECK THE STEERING WHEEL CLOCKSPRING TO ECM CIRCUITS FOR HIGH RESISTANCE
1. Disconnect the ECM electrical connector, PI01.
2. Measure the resistance between SW08, pin 06 (YG) and PI01, pin 48 (YG).
3. Measure the resistance between SW08, pin 08 (YR) and PI01, pin 47 (YR).

- Is either resistance greater than 5 ohms?

-> Yes
REPAIR the high resistance circuit. TEST the system for normal operation.

-> No
