A : P0568. CHECK SPEED CONTROL INPUT WIRE FOR OPEN CIRCUIT/HIGH RESISTANCE

A1 : CHECK INTERNAL STEERING WHEEL CIRCUIT FOR OPEN CIRCUIT/HIGH RESISTANCE (INPUT)

1. Disconnect steering wheel internal connector, SW5.
2. Disconnect steering wheel connector, SW4.
3. Measure the resistance between SW5, pin 4 (YR) and SW4, pin 1 (YR).

Is the resistance less than 5 ohms?
Yes
Goto A3

No
INSTALL a new steering wheel assembly. CLEAR the DTC. TEST the system for normal operation.

A2 : CHECK INTERNAL STEERING WHEEL CIRCUIT FOR OPEN CIRCUIT/HIGH RESISTANCE (SIGNAL)

1. Measure the resistance between SW5, pin 2 (B) and SW4, pin 3.

Is the resistance less than 5 ohms?
Yes
Goto A3

No
INSTALL a new steering wheel assembly. CLEAR the DTC. TEST the system for normal operation.

A3 : CHECK STEERING WHEEL CASSETTE FOR OPEN CIRCUIT/HIGH RESISTANCE (INPUT)

1. Disconnect steering wheel Cassette connector, IP34.
2. Reconnect steering wheel internal connector, SW5.
3. Measure the resistance between SW5, pin 4 (YR) and IP34, pin 8 (YR).

Is the resistance less than 5 ohms?
Yes
Goto A4

No
INSTALL a new steering wheel Cassette assembly. CLEAR the DTC. TEST the system for normal operation.

A4 : CHECK STEERING WHEEL CASSETTE FOR OPEN CIRCUIT/HIGH RESISTANCE (SIGNAL)

1. Disconnect steering wheel cassette connector, IP34.
2. Measure the resistance between SW5, pin 2 (B) and IP34, pin 6 (YG).

Is the resistance less than 5 ohms?
Yes
Goto A5

No
INSTALL a new steering wheel cassette assembly. CLEAR the DTC. TEST the system for normal operation.

A5 : CHECK INPUT LEAD FROM PCM TO STEERING WHEEL CASSETTE FOR OPEN CIRCUIT/HIGH RESISTANCE

1. Disconnect PCM electrical connector, EN16.
2. Measure the resistance between IP34, pin 8 (YR) and EN16, pin 47 (YR).

Is the resistance less than 5 ohms?
Yes
Goto A6

No
REPAIR the circuit between EN16, pin 47 and IP34, pin 8. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

A6 : CHECK SIGNAL LEAD FROM PCM TO STEERING WHEEL CASSETTE FOR OPEN CIRCUIT/HIGH RESISTANCE

1. Measure the resistance between IP34, pin 6 (YG) and EN16, pin 48 (YG).

Is the resistance less than 5 ohms?
Yes
Goto B1

No
REPAIR the circuit between EN16, pin 48 and IP34, pin 6. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
