TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMS
2.CONNECTOR INSPECTION
1. Disconnect ABS actuator and electric unit (control unit) connector E33.
2. Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace as necessary.
3.CHECKING SOLENOID POWER AND GROUND
1. Check voltage between ABS actuator and electric unit (control
unit) harness connector E33 and body ground.
2. Check resistance between ABS actuator and electric unit (con-
trol unit) harness connector E33 and body ground.
OK or NG
OK >> Perform self-diagnosis again. If the same results
appear, replace ABS actuator and electric unit (control
unit). Refer to BRC-35, "
Removal and Installation".
NG >> Repair the circuit.

CVT SYSTEM
Hydraulic Control System
INFOID:0000000001703438
TCM FunctionINFOID:0000000001703439
The function of the TCM is to:
• Receive input signals sent from various switches and sensors.
• Determine required line pressure, shifting point, and lock-up operation.
• Send required output signals to the step motor and the respective solenoids.
CONTROL SYSTEM OUTLINE
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.

Engine Brake Adjustment
CAUTION:
Mode of “+1”“0”“-1”“-2”“OFF” can be selected by pressing the “UP”“DOWN” on CONSULT-III screen.
However, do not select mode other than “0” and “OFF”. If the “+1” or “-1” or “-2” is selected, that
might cause the irregular driveability.
Check CVT Fluid Deterioration Date
CAUTION:
Touch “CLEAR” after changing CVT fluid, and then erase “CVTF DETERIORATION DATE”.

• TCM controls starter relay in IPDM E/R.
• TCM switches starter relay ON at “P” or “N” position and allows to crank engine.
• Then it prohibits cranking other than at “P” or “N” position.

• Diagnostic trouble code “P0615 STARTER RELAY/CIRC” with CONSULT-III is detected when starter relay
switched ON other than at “P” or “N” position. (or when switched OFF at “P” or “N” position).
Possible CauseINFOID:0000000001703479
• Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
• Starter relay
DTC Confirmation ProcedureINFOID:0000000001703480
CAUTION:

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
