Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

Diagnostic Procedure

2. 

CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT-II

1.

Disconnect ECM harness connector.

2.

Disconnect IPDM E/R harness connector E9.

3.

Check continuity between ECM terminal 104 and IPDM E/R terminal 47.
Refer to Wiring Diagram.

4.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 4.

NG

>> GO TO 3.

3. 

DETECT MALFUNCTIONING PART

Check the following.

Harness connectors E108, M15

Harness for open or short between ECM and IPDM E/R

>> Repair open circuit or short to ground or short to power in harness or connectors.

4. 

CHECK FUSE

1.

Disconnect 15A fuse.

2.

Check 15A fuse for blown.

OK or NG

OK

>> GO TO 8.

NG

>> Replace 15A fuse.

5. 

CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-I

1.

Check voltage between ECM terminal 3 and ground under the
following conditions with CONSULT-II or tester.

OK or NG

OK

>> GO TO 8.

NG

>> GO TO 6.

6. 

CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT-II

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connector.

3.

Disconnect IPDM E/R harness connector E8.

4.

Check continuity between ECM terminal 3 and IPDM E/R terminal 42.
Refer to Wiring Diagram.

5.

Also check harness for short to ground and short to power.

OK or NG

OK

>> GO TO 8.

NG

>> GO TO 7.
