DEALER SMM INFO FOR EPB DTC CODES C2007-11 AND C2008-11.
THE MOST LIKELY CAUSE OF A CIRCUIT SHORT TO GROUND FAULT IS HARNESS /
MOTOR LINK LEAD DAMAGE. START ANY DIAGNOSIS WITH A VISUAL INSPECTION
UNDER THE WHEEL ARCH / UNDER BODY FOR OBVIOUS SIGNS OF HARNESS / LINK
LEAD DAMAGE AND FOR POORLY LATCHED CONNECTORS.
IF THERE ARE NO OBVIOUS SIGNS OF DAMAGE THEN CARRY OUT THE FOLLOWING
DIAGNOSTIC PROCEDURE:1) CHECK FUSE FOR AFFECTED SIDE.
2) CHECK ECU GROUND CONNETIONS TO VEHICLE CHASSIS (STUD G4D152-1) (CHECK
FOR CORROSION/SCREW TORQUE/LOOSE CONNECTION/PAINT).
3) REMOVE THE AFFECTED CALIPER ACTUATOR AND SWAP WITH THE UN AFFECED
CALIPER ACTUATOR (REFER TO TOPIX FOR REMOVAL AND REFITMENTMENT
PROCESS), ACTUATE THE EPB VIA SWITCH. CHECK IF THE FAULT FOLLOWS THE
ACTUATOR. IF IT DOES THE ACTUATOR IS FAULTY. IF IT DOES NOT THE FAULT IS
LIKELY TO BE IN THE LINK LEAD/CONNECTORS ON THE FAULTY SIDE.
4) CHECK THE LINK LEAD, CHECK THE PINS FOR CORROSION ON BOTH ACTUATOR
AND LINK LEAD. CHECK THE SEALS ARE PRESENT BOTH INNER AND

OUTER

LINK LEAD SEALS – INNER AND OUTER. CHECK FOR PRESENCE AND
DAMAGE.

CHECK THAT PINS ARE
NOT BACKED OUT. CHECK
FOR CORROSION.

(CHAFING, PINCHING AND STRETCHING).

MOTOR LINES AND GND ON THE ECU. USING PINS 12 OR 27 (MULTIMETER
