INSPECTION PROCEDURE
1. Preparation (See step "1" of DTC B1111/B1112 - Battery voltage too high/low "Inspection Procedure").
2. Check Satellite circuit (Communication error).




PREPARATION
Check continuity between SRSCM connector and satellite connector as high (+) and high, low (-) and low (-).

OK: Continuity

NG: Replace harness between SRSCM and Satellite sensor.

OK: Continue to next step.

3. Check Satellite sensor (Defect).

PREPARATION
1. Turn ignition switch to LOCK.
2. Disconnect negative (-) terminal cable from the battery, and wait at least 30 seconds.
3. Connect satellite connector.
4. Connect negative (-) terminal cable to the battery, and wait at least 30 seconds.




CHECK:
1. Turn ignition switch to ON, and wait at least 30 seconds.
2. Clear malfunction code stored in memory with Hi-scan.
3. Turn ignition switch to LOCK, and wait at least 30 seconds.
4. Turn ignition switch to ON, and wait at least 30 seconds.
5. Using Hi-scan, check DTC.

DTC is not output.

HINT: Codes other than these ones may be output at this time, but they are not relevant to this check.

NG: Replace Satellite sensor.

OK: From the result of the above inspection, the malfunctioning part can now be considered normal.
