2000 HONDA CR-V Connectors

Precautions/Procedures
Disconneeting the Airbag Connectors and the Seat Belt Tensioner
Connectors (cont'd)
1.Disconnect the battery negative cable, then discon-
nect the positive cable from the battery. and wait at
least three minutes.
Disconnect the airbag and tensioner connectors
lsee page 24-22).
Driver's Airbag:
. Remove the access panel from the steering
wheel, then disconnect the 2P connector
between the driver's airbag and cable reel. When
disconnected, the airbag connector is automati-
callv shorted.
DRIVER'S AIRBAG2P CONNECTOR
Front Passsng€/sAirtag:
. Disconnect the 2P connector between the front
passenger's airbag and SRS main harness. When
disconnected. the airbag connector is automati-
callY shorted.
24-24
ACCESS PANEL
Seat Bslt Tensioner (38 - 00 modebl:
. Remove the left and (or) right center pillar lower
trim panels (see section 20).
. Disconnect the seat belt tensioner 2P connectors
from the left side wire harness (driver's side) and
(or) the right side wire harness (front passenger's
side). When disconnected. the seat belt tensioner
is automatically shorted.

Troubleshooting
Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion in memory, For easier troubleshooting, this data can be retrieved via a data link circuit.
. When you turn the ignition switch ON (ll). the SRS indicator will come on. lf it goes off after six seconds, the system is
normal.
. lf there is 8n abnormality, the system locates and defines the problem. stores this information in memory, and turns
the SRS indicator light on. The data will remain in the memory even when the ignition switch is turned off or if the bat-
terv is disconnected.
. When you connect the SCS service connector to the service check connector (2P), and turn the ignition switch ON (ll),
the SRS indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting forthis code.
Precsutions
. Use only a digital multimeter to check the system. lf it's not a Honda multimeter. make sure its output is 10 mA (0.01 A)
or less when switched to the smallest value in the ohmmeter range. A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment and possible injury.
. Whenever the ignition switch isON (ll). or has been turned OFF for less than three minutes, be careful nottobumpthe
SRS unit; the airbags could accidentally deploy and cause damage or injuries.
. Before you remove the SRS main harness, disconnect the airbag and tensioner connectors (see page 24-23).
. Make sure the battery is sufficiently charged (see section 23). lf the battery is dead or low, measuring values won't be
correct.
. Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect the terminals
with a jumper wire. Use only the backprobe set and the SCS service connector.
For backprobing spring-loaded lock type con nectors, .efet to page 24-22.
Reading the DTC
When the SRS indicator light is on, read the DTC using one of these methods;
A. Connect the Honda PGM Tester to the 16P Data Link Connector {DLC), and follow the tester's prompts. lf the tester
indicates no DTC, DTC 9-1 and DTC 9-2, double-check by jumping the service check connector (2P) and watching the
SRS indicator light (see next page).
