YES: Repair or replace the damaged components(s). Then go to Step 8 .  
NO: An open circuit may be present in the ground circuit. Repair the 
wiring harness between ABS-ECU connector A-02 terminals 2, 18 and the 
body ground. Then go to Step 8 .  
STEP 5. Check the battery. 
Check the battery (Refer to BATTERY TEST
 ).

INSPECTION PROCEDURE 5: FAULTY ABS OPERATION TECHNICAL DESCRIPTION (COMMENT) The cause depends on driving and road surface conditions, so diagnosis may be 
difficult. However, if no diagnostic trouble code is displayed, carry out the 
following inspection. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THIS CASE:) 
Malfunction of the hydraulic unit  
DIAGNOSIS Check the hydraulic unit (Refer to POINTS IN WAVEFORM MEASUREMENT
 ). If the hydraulic unit (integrated with ABS-ECU) is 
malfunctioning, replace it. Then check that the malfunction symptom is eliminated. 
STEP 1. Hydraulic unit check 
Refer to POINTS IN WAVEFORM MEASUREMENT
 . 
Q: Is the hydraulic unit normal?  
YES: Go to Step 2.  
NO: Connect the brake pipes correctly, repair the external brake lines, or 
replace the hydraulic unit.  
STEP 2. Verify that the condition described by the customer exists. 
Q: Can any faults be found with the brake operation?

4. Inspect wire harness between SRS ECU connector C-26, terminal No. 20 
(Orange/Blue wire) and Data Link Connector C-23, terminal No. 7 
(Orange/Blue wire), including connector C-104, for damage, loose connectors 
or poor connections. If wire harness is okay, go to step 7 . If wire harness is not 
okay, replace wire harness. Go to step 7 .  
5. Inspect wire harness between SRS ECU connector C-26, terminals No. 15 
(Black wire) and ground. If wire harness is okay, go to step 7 . If wire harness 
is not okay, replace wire harness. Go to step 7 .  
6. Inspect wire harness between SRS ECU connector C-26, terminals No. 13 
(Black/White wire) and No. 16 (Black/Yellow wire) and ignition switch 
connector C-308, including connectors C-211 and C-215. See Fig. 22
 . If wire 
harness is okay, go to next step. If wire harness is not okay, replace wire 
harness. Go to step 7 .  
7. Connect all SRS connectors. If scan tool communicates normally with SRS, 
repair is complete. If communication is not normal, intermittent condition may 
exist.
