DTC B1032: MICU Collision Detection Signal (CDS) Input Error

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures (see PRECAUTIONS AND PROCEDURES ) and General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).

Clear the DTC with the HDS.
Turn the ignition switch OFF, and then back ON (II).
Check for DTC with the HDS.
Is DTC B1032 indicated?

YES - Go to step 4.

NO - Intermittent failure the system is OK at this time. Go to Troubleshooting Intermittent Failures (see TROUBLESHOOTING INTERMITTENT FAILURES ).
Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes (see PRECAUTIONS AND PROCEDURES ).
Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 under PRECAUTIONS AND PROCEDURES ).
Disconnect under-dash fuse/relay box connector P (30P).
Measure the resistance between the No. 21 terminal of SRS unit connector A (28P) and the No. 21 terminal of under-dash fuse/relay box connector P (30P). There should be 0-1.0 Ω.

Is the resistance as specified?

YES - Go to step 8.

NO - Open in the BLU (YEL) wire of dashboard wire harness A; replace dashboard wire harness A.
'05-06 models: disconnect OnStar control unit connector A (22P) (see CONTROL UNIT REPLACEMENT ).
Measure the 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 MΩ.

Is the resistance as specified?

YES - Go to step 10.

NO - Short to ground in dashboard wire harness A; replace dashboard wire harness A.
Measure the voltage between the No. 21 terminal of SRS unit connector A (28P) and body ground. There should be 1.5 V or less.
