Table-A ABS Warning Lamp Circuit Check – Lamp Does Not Come “ON” at
Ignition Switch ON
CIRCUIT DESCRIPTION
Operation (ON/OFF) of ABS warning lamp is controlled by ABS control module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning lamp ON at the ignition
switch ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality in the system is detected, ABS
warning lamp is turned ON continuously by ABS control module. Also, it is turned ON continuously by lamp
driver module when the connector of ABS control module is disconnected.

2. Ignition switch 6. Brake warning lamp 10. ABS hydraulic unit/control module assembly
3. Circuit fuse 7. Lamp driver module 11. ABS hydraulic unit/control module connector
4. Combination meter 8. Parking brake switch
Step Action Yes No
1 1) Turn ignition switch ON.
Do other warning lamp come ON?Go to Step 2. Go to Step 4.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
Does ABS warning lamp light with ignition
switch ON?Substitute a known-good ABS
hydraulic unit/control module
assembly and recheck.Go to Step 3.
3 1) Remove combination meter.
Is bulb of ABS warning lamp in good condition?“BLU/ORN” circuit shorted to
ground. If OK, replace combina-
tion meter (lamp driver module).Replace bulb.
4 Is IG fuse in good condition? Open in “BLK/WHT” wire to
combination meter or poor con-
nection.Repair and replace.

DTC C1057 (DTC 57) – Power Source Circuit
DESCRIPTION
The ABS control module monitors the power source voltage at terminal “E136-18”. When the power source volt-
age becomes extremely high or low, this DTC will be set. As soon as the voltage rises or lowers to the specified
level, the set DTC will be cleared.
INSPECTION
1. Ignition switch 3. ABS hydraulic unit/control module assembly
2. Main fuse 4. ABS hydraulic unit/control module connector
Step Action Yes No
1 1) Connect a voltmeter between battery posi-
tive (+) terminal and body ground.
2) Start the engine and measure the maximum
voltage when racing the engine.
Is it over 18V?Check charging system
referring to “CHARGING
SYSTEM” section.Go to Step 2.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Keep the engine idling, measure the voltage
between terminal “E136-18” of ABS control
module and body ground.
Is it always under 9V?Check charging system
referring to “CHARGING
SYSTEM” section.
Imperfect short between
wire “GRN/ORN” and
ground.Poor connection of termi-
nal “E136-18” or “E136-
24” of the ABS control
module.
If the above are in good
condition, substitute a
known-good ABS hydrau-
lic unit/control module and
recheck.

ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-13
STEP 2. DIAGNOSTIC TROUBLE CODE (DTC)/FREEZE FRAME DATA CHECK
First, check DTC, referring to “DIAGNOSTIC TROUBLE CODE CHECK” in this section. If DTC is indicated,
record DTC and freeze frame data.
After that clear DTC referring to “DIAGNOSTIC TROUBLE CODE CLEARANCE” in this section. DTC indicates
malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the past and
the normal condition has been restored now. To check which case applies, check the symptom in question
according to Step 5 and recheck DTC according to Step 6, 7.
Attempt to diagnose a trouble based on DTC in this step only or failure to clear the DTC (including pending DTC)
in this step will lead to incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
STEP 3. and 4. VISUAL INSPECTION
Be sure to perform visual check of the following items that support proper function of the engine.
STEP 5. TROUBLE SYMPTOM CONFIRMATION
Based on information obtained in Step 1 “CUSTOMER COMPLAINT ANALYSIS” and Step 2 “DTC/FREEZE
FRAME DATA CHECK”, confirm trouble symptoms. Also, reconfirm DTC according to “DTC CONFIRMATION
PROCEDURE” described in each “DTC FLOW TABLE”.NOTE:
For A/T vehicle, if only DTC P0705, P0715, P0720, P0741, P0743, P0751, P0753, P0756, P0758, or P1875
is indicated in this step, proceed to “DIAGNOSIS” in SECTION 7B1.

Table A-1 Malfunction Indicator Lamp Circuit Check – Lamp Does Not Come
“ON” or Dims at Ignition Switch ON (But Engine at Stop)
WIRING DIAGRAM
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then,
ECM being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the engine
starts to run and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is detected,
MIL remains ON even when the engine is running.

6. Monitor connector (if equipped)
Step Action Yes No
1 MIL power supply check :
1) Turn ignition switch ON.
Do other indicator/warning lights in combination
meter comes ON?Go to Step 2. “IG METER” fuse blown,

METER” fuse and combi-
nation meter or poor cou-
pler connection at
