Navigation System

System Diagnosis Mode (cont'd)

GPS Offset Time

This screen is for factory use only. It allows adjustment

of the GPS time. This display updates in real time.

• "GPS Time" is the time as received from the GPS

satellites. It is in Greenwich Mean Time (GMT).

• "System Time" is the internal time used by the navi-

gation unit to calculate your position on the map.

It is also in Greenwich Mean Time (GMT).

• "Display Time" is the time shown on Setup screen 2

"Adjust Time Zone/Clock", and reflects any changes

due to daylight savings time or time adjustments

entered by the customer.

• Date, Hour, Minute, and "Set" buttons should not be

used.
Mic Level

This diagnostic allows you to independently test the

microphone and the TALK and BACK buttons on the

steering wheel (voice control switch). The microphone

and voice control switch are used to activate the voice

control system. The microphone is located near the map

light in the ceiling. It is directional, and works best if the

voice is coming from the drivers seat.

• Press the TALK button on the steering wheel, and in a

normal voice say "testing". The TALK indicator on

the screen should momentarily become green, and

the text "Now Recording..." should appear in yellow.

In addition, the Mic Level indicator should move at

least to the 6th bar. If the Talk indicator on the screen

does not briefly become green, then check the wiring

from the steering wheel talk button to the navigation

unit. If there is no "Mic Level" movement when you

speak, then you should check the wire running from

the microphone to the control unit.

• Press the BACK button on the steering wheel. This

should cause the Cancel indicator on the screen to

momentarily become green. If it does not briefly

change to green, then check the wiring from the

steering wheel BACK button to the navigation unit.ProCarManuals.com

chain.

65. Check that the engine/transmission is completely

free of vacuum hoses, fuel and coolant hoses and

electrical wiring.

66. Slowly raise the engine approximately 150 mm (6 in).

Check once again that all hoses and wires are discon-

nected from the engine/transmission.

67. Raise the engine all the way, and remove it from the

vehicle.ProCarManuals.com

2. To reinstall the connector, push it into position until

it clicks, then close its lid.
Precautions/Procedures

Inspection After Deployment

After a collision in which the airbags were deployed,

replace the deployed parts (airbag, seat belt tensioner

and side airbag), the SRS unit, the side impact sensor on

the side which deployed, and any related parts, and

inspect the following:

1. Inspect all the SRS wire harnesses. Replace, don't

repair, any damaged harnesses.

2. Inspect the cable reel for heat damage. If there is any

damage, replace the cable reel.

3. After the vehicle is completely repaired, turn the igni-

tion switch on. If the SRS indicator light comes on

for about 6 seconds and then goes off, the SRS sys-

tem is OK. If the indicator light does not function

properly, go to SRS Troubleshooting.

Disconnecting the SRS Connector

at the Fuse Box - '96 - 98 Models

CAUTION: Avoid breaking the connector; it's double-

locked.

1. First lift the connector lid with a thin screwdriver,

then press the connector tab down and pull the con-

nector out.
Wiring Precautions

• Never attempt to modify, splice or repair SRS wiring.

NOTE: SRS wiring harnesses are indicated by yellow

color.

• Be sure to install the harness wires so that they are not

pinched or interfering with other parts.

• Make sure all SRS ground locations are clean and

grounds are securely fastened for optimum metal-to-

metal contact. Poor grounding can cause intermittent

problems that are difficult to diagnose.ProCarManuals.com

Airbag

Replacement (cont'd)

CAUTION: Be sure to install the SRS wiring so that it is

not pinched or interfering with other parts.

5. Install new airbag(s):

Driver's Side: Place the driver's airbag in the steering

wheel, and secure it with new Torx bolts.

'96-98 Models
Front Passenger's Side:

• Place the front passenger's airbag in the dashboard.

• Tighten the front passenger's airbag mounting nuts.
