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.
Diagnostic ProcedureEBS01FFI
LHD MODELS WITHOUT XENON HEADLAMP
1. INSPECTION START
Do you have CONSULT-II?
Ye s o r N o
Yes >> GO TO 2.
No >> GO TO 3.

With CONSULT-II
1. Turn ignition switch ON.
2. Check “LOAD SIGNAL” in “DATA MONITOR” mode with CON-
SULT-II under the following conditions.
OK or NG
OK >> GO TO 4.
NG >> GO TO 8.
3. CHECK LOAD SIGNAL CIRCUIT OVERALL FUNCTION-I
Without CONSULT-II
1. Turn ignition switch ON.
2. Check voltage between ECM terminal 84 and ground under the
following conditions.
OK or NG
OK >> GO TO 5.
NG >> GO TO 8.

1. INSPECTION START
1. Check service records for any recent repairs that may indicate a related malfunction.
2. Check the current need for scheduled maintenance, especially for fuel filter and air cleaner filter. Refer to
MA-7, "
PERIODIC MAINTENANCE" .
3. Open engine hood and check the following:
–Harness connectors for improper connections
–Vacuum hoses for splits, kinks, or improper connections
–Wiring for improper connections, pinches, or cuts
4. Start engine and warm it up to the normal operating tempera-
ture.
>> GO TO 2.
2. PREPARATION FOR CHECKING IDLE SPEED
With CONSULT-II
Connect CONSULT-II to the data link connector.
Without CONSULT-II
Install diesel tacho tester to the vehicle.
