2. Turn the ignition switch to the "ON" position.
3. Check whether combination meter DTC U1102 has been set.
Q: Is combination meter DTC U1102 set?
YES: Replace the hydraulic unit (integrated with ABS-ECU)
NO: Replace the combination meter.
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.

Such shorts can damage fuses or components and may cause a second
Diagnostic Trouble Code (DTC) to set, making diagnosis of original problem
more difficult. Never use an analog volt/ohm meter or test light in place of a Digital Volt/Ohm
Meter (DVOM). Use only a DVOM with a maximum test current of 2 mA
(milliamps) at minimum range of resistance measurement. If SRS is not fully functional for any reason, DO NOT drive vehicle until
system is repaired and fully functional. DO NOT remove bulbs, modules,
sensors, or other components or in any way disable system from operating
normally. If SRS is not functional, park vehicle until repairs are made.
DISABLING & ACTIVATING AIR BAG SYSTEM To disable system, turn ignition off. Disconnect negative battery cable. Shield cable
end with electrical tape. Wait at least 60 seconds before servicing air bag system.
To activate system, reconnect negative battery cable. Check system operation. See SYSTEM OPERATION CHECK
.
DISPOSAL PROCEDURES DEPLOYED AIR BAG OR SEAT BELT PRETENSIONER Place deployed component in a strong plastic bag and seal tightly. Dispose of
component as you would any other part. No other special disposal procedure is
required. UNDEPLOYED AIR BAG OR SEAT BELT PRETENSIONER
WARNING:Accidental air bag deployment is possible. Personal
injury may result. Read and follow all WARNINGS
and AIR BAG SAFETY PRECAUTIONS
before
working on air bag system or related components.
NOTE: Undeployed air bag modules must be deployed before
disposal. Disposing of an undeployed air bag may violate
federal, state and/or local laws. This also applies to vehicles
that are to be scrapped.

1. Turn ignition on. If AIR BAG warning light comes on for 7 seconds and then
goes off, SRS is functioning properly. If AIR BAG warning light does not
function as described, turn ignition off. If AIR BAG warning light malfunction
or scan tool communication problems are encountered, diagnose malfunction
using appropriate table. SeeSCAN TOOL COMMUNICATION
SYMPTOMS (SINGLE
-STAGE AIR BAG SYSTEMS)
and SCAN TOOL
COMMUNICATION SYMPTOMS (DUAL

SYSTEMS)
tables.
2. Utilizing a laptop computer, check for Diagnostic Trouble Codes (DTCs) by
connecting Scan Tool (MB991958) to Data Link Connector (DLC), located
under left side of instrument panel, using Vehicle Communication Interface
(MB991824), USB Cable (MB991827) and Main Harness (MB991911). See
Fig. 18
. Turn ignition on and follow instructions provided with scan tool.
Diagnose displayed DTCs for appropriate air bag system. See SCAN TOOL

B1546 is not retrieved, system is normal at this time.
DTC B1547: CUT OFF FOR PASSENGER-SIDE AIR BAG MODULE 1. Connect scan tool to Data Link Connector (DLC). See INITIAL SRS
DIAGNOSTIC PROCEDURE
under DIAGNOSTICS. If scan tool is able to
diagnose CAN bus lines and CAN bus lines are satisfactory, go to next step. If
scan tool cannot diagnose CAN bus lines, repair CAN bus lines. Go to next
step.
2. Erase, then retrieve DTCs. Turn ignition off. If DTC B1547 is retrieved, go to
next step. If DTC B1547 is not retrieved, an intermittent condition may exist.
3. If DTCs other than DTC B1457 are retrieved, diagnose indicated DTC. See
