DTC B1-8x, B1-9x, B1-Ax, B1-Bx (‘‘x’’ can be
0 thru 9 or A thru F):

DTC B1032:

YES

Internal Failure of the Roll Rate Sensor

MICU Collision Detection Signal

(CDS) Input Failure

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-16) and General Troubleshooting Information
(see page 24-27).

1. Clear the DTC memory (see page 24-28).

2. Turn the ignition switch ON (II), and check that the

SRS indicator comes on for about 6 seconds and
then goes off.

Replace the roll rate sensor (see page

24-194). If the DTC returns, replace the SRS unit
(see page 24-188).

Intermittent failure, the system is OK at this

time. Go to Troubleshooting Intermittent Failures
(see page 24-29). If another DTC is indicated,
troubleshoot the DTC.

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-16) and General Troubleshooting Information
(see page 24-27).

1. Clear the DTC memory (see page 24-28).

2. Turn the ignition switch OFF, and then back ON (II).

3. Read the DTC (see page 24-27).

Go to step 4.

Intermittent failure, the system is OK at this

time. Go to Troubleshooting Intermittent Failures
(see page 24-29). If another DTC is indicated,
troubleshoot the DTC.

4. Turn the ignition switch OFF. Disconnect the

negative cable from the battery, and wait for 3
minutes.

5. Disconnect SRS unit connector A (28P) from the

SRS unit (see step 7 on page 24-26).

6. Disconnect MICU connector P (30P) from the under-

dash fuse/relay box (see page 22-61).

(cont’d)

Does the SRS indicator stay on, and is B1-8x,
B1-9x, B1-Ax, or B1-Bx indicated?

Is DT C B1032 indicated?

7. Measure the resistance between the No. 21

terminal of SRS unit connector A (28P) and the
No. 10 terminal of the multiplex integrated control
unit connector P (30P) (see page 22-61). There
should be 0

1.0

Go to step 8.

Open in the dashboard wire harness; replace

the dashboard wire harness.

8. Check resistance between the No. 21 terminal of

SRS unit connector A (28P) and body ground. There
should be an open circuit or at least 1 M

Go to step 9.

Short to ground in the dashboard wire

harness; replace the dashboard wire harness.

9. Check for voltage between the No. 21 terminal of

SRS unit connector A (28P) and body ground. There
should be 1.0 V or less.

Short to power in the dashboard wire

harness; replace the dashboard wire harness.

Faulty SRS unit; replace the SRS unit

(see page 24-188).

1. Turn the ignition switch ON (II), and see if the other

indicators come on (brake system, etc).

Go to step 2.

Go to step 9.

2. Turn the ignition switch OFF, then remove the

gauge control module (see page 22-263).
Disconnect the gauge control module connector A
(20P) and gauge control module connector C (20P)
from the gauge control module.

3. Measure the resistance between the No. 10

terminal of gauge control module connector A
(20P) and body ground. There should be 0

1.0

Go to step 4.

Open in the BLK wire of the dashboard wire

harness, or faulty body ground terminal (G401)
(see page 22-28). If the body ground terminal is OK,
replace the dashboard wire harness.

4. Measure the voltage between the No. 17 terminal

of the gauge control module connector C (20P) and
body ground within the first 6 seconds after turning
the ignition switch ON (II). There should be about
1.0 V for 6 seconds and then about 11 V.

Faulty SRS indicator circuit in the gauge

control module; replace the gauge control
module.

Go to step 5.

5. Turn the ignition switch OFF. Disconnect the

negative cable from the battery, and wait for 3
minutes.

6. Disconnect SRS unit connector A (28P) from the

SRS unit (see step 7 on page 24-26).

7. Reconnect the negative cable to the battery.

8. Measure the voltage between the No. 17 terminal

of gauge control module connector C (20P) and
body ground. Turn the ignition switch ON (II), and
measure voltage. There should be 0.5 V or less.

Faulty SRS unit; replace the SRS unit

(see page 24-188).

Short to power in the PNK wire of the

dashboard wire harness; replace the dashboard
wire harness.

9. Turn the ignition switch OFF. Check the No. 21

(7.5 A) fuse in the under-dash fuse/relay box.

Go to step 11.

Go to step 10.

10. Measure the voltage between the No. 20 terminal

of the gauge control module connector A (20P) and
body ground. Turn the ignition switch ON (II), and
measure the voltage. There should be battery
voltage.

Faulty SRS indicator circuit in the gauge

control module or poor connection at gauge control
module connector A (20P) and the gauge control
module; if the connection is OK, replace the gauge
control module.

Open in the under-dash fuse/relay box No. 21

(7.5 A) fuse circuit, or open in the dashboard wire
harness. If the under-dash fuse/relay box is OK,
replace the dashboard wire harness.

11. Replace the No. 21 (7.5 A) fuse, then check to see if

the indicators comes on.

The system is OK at this time.

Repair the short to ground in the under-dash

fuse/relay box No. 21 (7.5 A) fuse circuit.
