CAN COMM CIRCUITWhen a TCM is not transmitting or receiving CAN communication
signal for 2 seconds or moreU1000CVT-53
STARTER RELAY/CIRCIf this signal is ON other than in “P” or “N” position, this is judged to
be a malfunction
(And if it is OFF in “P” or “N” position, this is judged to be a malfunc-
tion too)P0615CVT-56

TROUBLE DIAGNOSIS

A/T TCC S/V FNCTN

There is a big difference engine speed and primary speed when
TCM lock-up signal is on

CVT cannot perform lock-up even if electrical circuit is good

TCM detects as irregular by comparing difference value with slip
rotationP0744CVT-94
L/PRESS SOL/CIRC

Normal voltage not applied to solenoid due to open or short cir-
cuit

TCM detects as irregular by comparing target value with monitor
valueP0745CVT-97
PRS CNT SOL/A FCTNUnexpected gear ratio was detected in the LOW side due to exces-
sively low line pressureP0746CVT-102
PRS CNT SOL/B FCTNSecondary pressure is too high or too low compared with the com-
manded value while drivingP0776CVT-105
PRS CNT SOL/B CIRC

Normal voltage not applied to solenoid due to cut line, short, or
the like

TCM detects as irregular by comparing target value with monitor
valueP0778CVT-108
MANUAL MODE SWITCHWhen an impossible pattern of switch signals is detected, a mal-
function is detectedP0826CVT-113
TR PRS SENS/A CIRCSignal voltage of the transmission fluid pressure sensor A (second-
ary pressure sensor) is too high or too low while drivingP0840CVT-118
PRESS SEN/FNCTNCorrelation between the values of the transmission fluid pressure
sensor A (secondary pressure sensor) and the transmission fluid
pressure sensor B (primary pressure sensor) is out of specificationP0841CVT-123
TR PRS SENS/B CIRCSignal voltage of the transmission fluid pressure sensor B (primary
pressure sensor) is too high or too low while drivingP0845CVT-126
SEC/PRESS DOWNSecondary fluid pressure is too low compared with the commanded
value while drivingP0868CVT-131
TCM-POWER SUPPLY

When the power supply to the TCM is cut OFF, for example
because the battery is removed, and the self-diagnosis memory
function stops

This is not a malfunction message (Whenever shutting OFF a
power supply to the TCM, this message appears on the screen)P1701CVT-134
TP SEN/CIRC A/TTCM does not receive the proper accelerator pedal position signals
(input by CAN communication) from ECMP1705CVT-139
ESTM VEH SPD SIG

CAN communication with the ABS actuator and the electric unit
(control unit) is malfunctioning

There is a great difference between the vehicle speed signal from
the ABS actuator and the electric unit (control unit), and the vehi-
cle speed sensor signalP1722CVT-141
CVT SPD SEN/FNCTNA rotation sensor error is detected because the gear does not
change in accordance with the position of the stepping motor
CAUTION:
One of the “P0720 VEH SPD SEN/CIR AT”, the “P0715 INPUT
SPD SEN/CIRC” or the “P0725 ENGINE SPEED SIG” is dis-
played with the DTC at the same timeP1723CVT-143

CONSULT-II Function (METER A/C AMP)BKS001SO
CONSULT-II performs the following functions communicating with the unified meter and A/C amp.
CONSULT-II BASIC OPERATION
Refer to GI-34, "CONSULT-II Start Procedure"
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which performs CAN communication.
SELF-DIAGNOSTIC RESULTS
Display Item List
“TIME” indicates the condition of the self-diagnostic results judged by each signal input.

Normal: In case of operating properly at the present in spite of having malfunction in the past, then “TIME”
indicates “1-63”.

Malfunction: Soon after detecting malfunctions by self-diagnoses or current malfunction, “0” is indicated.
After returning to normal condition, every time when ignition switch is turned to “OFF” from “ON”, time will be
added like “1”→“2”→“3”···“63”, and when the key operation is performed 64 times, the result of the self-diag-
noses will be erased. And if any malfunction is detected again, “0” will be indicated.

Display item [Code] Malfunction is detected when...
CAN COMM CIRC [U1000]Malfunction is detected in CAN communication.
CAUTION:
Even when there is no malfunction on CAN communication system, malfunction may be
misinterpreted when battery has low voltage (when maintaining 7-8V for about 2 seconds)
or 10A fuse [No. 19, located in the fuse block (J/B)] is disconnected.
METER COMM CIRC [B2202]Malfunction is detected in communication of between combination meter and unified meter and
A/C amp.
VEHICLE SPEED CIRC [B2205]When an erroneous speed signal is input for 1 second.
CAUTION:
Even when there is no malfunction on speed signal system, malfunction may be misinter-
preted when battery has low voltage (when maintaining 7-8V for about 2 seconds).
