DIAGNOSTIC PROCEDURE
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-60, "
SELF-DIAGNOSTIC RESULT MODE" .
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated in the results?
YES >> Check CAN communication line. Refer to CVT-68, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK TCM POWER SOURCE
1. Turn ignition switch ON.
2. Check voltage between TCM connector terminals and ground.
Refer to CVT-146, "
Wiring Diagram — CVT — POWER" .
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING ITEM
Check the following.

Harness for short or open between ignition switch and TCM connector terminal 10, 19
Refer to CVT-146, "
Wiring Diagram — CVT — POWER" .

10 A fuse (No.49, located in the IPDM E/R). Refer to CVT-146, "Wiring Diagram — CVT — POWER" .

Ignition switch. Refer to PG-4, "POWER SUPPLY ROUTING CIRCUIT" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK TCM GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM connector terminals and ground.
Refer to CVT-146, "
Wiring Diagram — CVT — POWER" .
OK or NG

CAN COMM CIRC [U1000]Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunction on CAN communication system, mal-
function may be misinterpreted when battery has low voltage (when
maintaining 7 - 8 V for about 2 seconds) or 10A fuse [No. 14, located in
the fuse block (J/B)] is removed.DI-22
VEHICLE SPEED CIRC [B2205]Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunctions
may be misinterpreted when battery has low voltage (when maintaining 7
- 8 V for about 2 seconds).DI-18
