5. CHECK FUEL TRANSPORT PUMP POWER SUPPLY AND GROUND CIRCUIT FOR OPEN AND
SHORT
1. Turn ignition switch OFF.
2. Disconnect fuel transport pump harness connector.
3. Check harness continuity between fuel transport pump relay ter-
minal 3 and fuel transport pump terminal 1 and between fuel
transport pump terminal 2 and ground. Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 7.
NG >> GO TO 6.
6. DETECT MALFUNCTIONING PART
Check the following.

Harness connector B22, B128

Harness for open or short between fuel transport pump relay and fuel transport pump

Harness for open or short between fuel transport pump and ground
>> Repair open circuit or short to ground or short to power in harness or connectors.
7. CHECK FUEL TRANSPORT PUMP RELAY OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 39 and fuel transport pump relay terminal 2. Refer to
Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 9.
NG >> GO TO 8.
8. DETECT MALFUNSTIONING PART
Check the following.

Harness connector M17, B1 (LHD models)

Harness connector M18, B2 (RHD models)

Diagnostic ProcedureEBS0126N
1. CHECK START SIGNAL OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch ON.
2. Check “START SIGNAL” in “DATA MONITOR” mode with CON-
SULT-II under the following conditions.
Without CONSULT-II
Check voltage between ECM terminal 99 and ground under the fol-
lowing conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2. CHECK START SIGNAL INPUT SIGNAL CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector and ignition switch harness connector.
3. Check harness continuity between ECM terminal 99 and ignition switch terminal 6.
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.

10A fuse

Fuse block (J/B) connectors M1, E102

Harness for open or short between ECM and ignition switch
>> Repair open circuit or short to ground or short to power in harness or connectors.
