2. If NG, check again with control cable disconnected from
manual shaft of CVT assembly. Refer to step 1.
3. If OK on step 2, adjust control cable. Refer to AT-114.
4. If NG on step 2, remove PNP switch from CVT and check
continuity of PNP switch terminals. Refer to step 1.
5. If OK on step 4, adjust PNP switch. Refer to AT-114.
6. If NG on step 4, replace PNP switch.

Diagnostic ProcedureNCAT0042
1 CHECK DTC WITH ECM
Perform diagnostic test mode II (self-diagnostic results) for engine control. Check ignition signal circuit condition.
OK or NG
OK (With CONSULT-II)©GO TO 2.
OK (Without CONSULT-II)©GO TO 3.
NG©Check ignition signal circuit for engine control. Refer to EC section (IGNITION SIGNAL).
2 CHECK INPUT SIGNAL (With CONSULT-II)
With CONSULT-II
1. Start engine.
2. Select ªECU INPUT SIGNALSº in ªDATA MONITORº mode for ªCVTº with CONSULT-II.
3. Read out the value of ªENGINE SPEEDº.
Check engine speed changes according to throttle position.
OK or NG
OK©GO TO 4.
NG©Check the following items:
IHarness for short or open between TCM and ECM
IResistor and ignition coil
Refer to EC section (IGNITION SIGNAL).
3 CHECK INPUT SIGNAL (Without CONSULT-II)
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM terminal 39 and ground.
Voltage (Idle speed):
0.5 - 1.5V
SAT424JA
OK or NG
OK©GO TO 4.
NG©Check the following items:
IHarness for short or open between TCM and ECM
IResistor and ignition coil
Refer to EC section (IGNITION SIGNAL).
4 CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure, AT-66.
OK or NG
OK©INSPECTION END
NG©1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness con-
nector.
