STEP

INSPECTION

ACTION

1

•  Measure the battery voltage.

•  Is the battery voltage 10.0—14.0 V?

Yes

Go to the next step.

No

Replace or recharge the battery.

(See BATTERY RECHARGING [MZI-3.7].)

2

•  Inspect the TCM related harnesses, connectors and fuses.

•  Are they normal?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts according to the inspection result.

3

•  Switch the ignition ON.

•  When the selector lever is moved, does the gear position indicator light indication correspond to the selector lever position?

•  Also, when other positions are selected from N or P during idling, does the vehicle move within 1—2s?

Yes

Go to the next step.

No

Inspect TR switch (built in TCM) and the adjustment of selector cable and TR switch. Repair or replace malfunctioning parts.

(See TRANSAXLE RANGE (TR) SWITCH INSPECTION [AY6A-EL, AY6AX-EL].)

(See SELECTOR CABLE ADJUSTMENT.)

(See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

If the selector cable and TR switch are normal, go to the next step.

4

•  Perform the road test.
(See ROAD TEST [AY6A-EL, AY6AX-EL].)

•  Is the ATX operating normally?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts according to the inspection result.

5

•  Perform the stall test.
(See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].)

•  Is the stall speed within the specified?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts according to the inspection result.

6

•  Perform the time lag test.
(See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].)

•  Is the ATX operating normally?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts according to the inspection result.

7

•  Perform the line pressure test.
(See MECHANICAL SYSTEM TEST [AY6A-EL, AY6AX-EL].)

•  Is the line pressure within the specified?

Yes

Perform the symptom troubleshooting and follow the procedures.

No

Repair or replace any malfunctioning parts according to the inspection result.

8

•  Inspect the ATF color and condition.
(See AUTOMATIC TRANSAXLE FLUID (ATF) INSPECTION [AY6A-EL, AY6AX-EL].)

•  Are the ATF color and odor normal?

Yes

Go to the next step.

No

Repair or replace any malfunctioning parts according to the inspection result.

Flush the ATX and cooler line if necessary.

9

•  Inspect the value at the following PCM and TCM PIDs using the M-MDS.
(See PCM INSPECTION [MZI-3.7].)

(See ON-BOARD DIAGNOSTIC SYSTEM PID/DATA MONITOR INSPECTION [AY6A-EL, AY6AX-EL].)

PCM PIDs:

―  APP1

―  APP2

―  BOO

―  CHT

―  RPM

―  VPWR

TCM PIDs:

―  TSS

―  OSS

―  VSS

―  TFT

―  TFTV

―  TR

―  THOP

―  MNL SW

―  UP_SW

―  DWN_SW

•  Are the PID values normal?

Yes

Perform the symptom troubleshooting and follow the procedures.

No

Repair or replace any malfunctioning parts according to the inspection result.
