Test
SRS components are located in this area. Review the
SRS component locations (see page 23-13) andprecautions and procedures {see page 23-'l4) in the SRS
section before performing repairs or service.
1, Remove the driver's dashboard lower cover {seepage 20-59).
2. Disconnect the 5P connector from the under-dash
fuse/relay box.

Gauge Assembly Replacement
1.Remove the instrument panel (see page 20-59),
then remove the upper column cover {see page 17-
Place a clean shop towel (A) under the gauge
assembly to prevent scratching the steering
colum n or dash panel.
Remove the screws from the gauge assembly (B).
Disconnect the connectors (C), and remove thegauge assemDry.
Installthe gauge assembly in the reverse order of
removal.

Troubleshooting
Before testing, check the No. I { 10A) fuse in the under-
hood fuse/relay box and the No. '10 (7.5A) fuse in the
under dash fuse/relay box.
1. Start the engine, and check the malfunction
indicator lamp (MlL).
Does the MIL come on?
YES- Troubleshoot the cause of the ECM DTC (see
page 1 1-57), and recheck.
NO-Go to step 2.
2. Check for a multiplex control unit DTC (see page
22,168).
ls a DTC ind icated?
YES Troubleshooting the cause of the multiplex
control unit DTC {see page 22-168), and recheck.
NO Go to step 3.
3. Do the communication line check with the self-
diagnosis procedure (see page 22-56).
ls the word "Error" indicated on the odo/ttip
d isplay ?
YES The gauge cannot receive the signal from the
multiplex control unit and the ECI\,4. Check for an
open in the WHT/GRN wire (gauge connector
terminal B 13). lf no open is found, go to step 5.
NO Go to step 4.
4. Do the gauge drive circuit check with the self-
diagnosis procedure (see page 22-56).
Does the temperature gauge needle sweep lrom
the minimum position to the maximum, then tetutn
to the minimum position?
YES Go to step 5.
NO Replace the gauge assembly.l
5. Substitute a known-good ECM and recheck.
Did the symptom/ ind ication go away?
YES Replace the ECM.
NO Substitute a known good gauge assembly. lf
the symptom/indication goes away, replace thegauge assembly.l

Turn the ignition switch OFF.
Connect the other test harness connector (A) to the
VSS (B),
11.Raise the front of the vehicle, and make sure it is
securely supported.
Put the vehicle in neutral with the ignition switch

Slowly rotate one wheel with the other wheel
blocked.
Does voltage pulse ttom 0 to about 5 V ot morc?
YES Go to step 14.

Does voltage pulse f rom 0 to about 5 V or more?
YES - Replace the speedometer assembly.I
NO Repair open in the BLUMHTwiTe between
the VSS and the speedometer.l

Exterior Lights
Daytime Running Lights Control Unit Input Test - Canada
The DRL indicator light in the gauge assembly will come on when you turn the ignition switch to ON (ll) with the
headlight switch off and the parking brake se1. lt should go off when you turn on the headlight switch and release the
parking brake. lf it comes on at any other time, do the control unit input test.
NOTE: When the daytime running lights are on, the high beam indicator will glow at half its normal intensity.
1. Remove the driver's dashboard lower cover (see page 20-60).
2, Disconnectthe l4Pconnector(A) from thedaytime running lightscontrol unit(B).
RED/BLUGNN/BLKRED/BLUGRN/BLKGRN/ORN
BLU/RED RED/YEL YEL/RED
Inspect the connector and socket terminals to be sure they are all making good contact.
. lf the terminals are bent, loose orcorroded, repairthem as necessary, and recheckthe system.
' lf the terminals look OK, go to step 4.
