Code No.91 Side impact sensor (L.H.) power supply circut
system
This diagnosis code is output if the power supply voltage of the side impact sensor
(L.H.) drops below the rated value for a continuous period of 5 seconds or more.
However, code No.91 will be automatically cleared and the SRS warning lamp will
awitch off if the condition returns normal.
Measure at side impact sensor (L.H.) connector D-18.
Disconnect the connector, and measure at the harness side
connector.
Connect the battery (–) terminal.
Ignition switch: ON
Voltage between terminal 3 and body earth
OK: 9 V or more
Continuity between terminal 1 and body earth
Replace the side impact sensor (L.H.).
Code No.92, 95 Side impact sensor system
Code No.92 is output when a fault is detected in the side impact sensor (L.H.).
Code No.95 is output when a fault is detected in the side impact sensor (R.H.).
The defective parts and trouble causes for each diagnosis code No. are as follows.
Code No. Defective parts
Analog G-sensor
92
95 95
Replace the side impact sensor (L.H.) (code No.92).
Replace the side impact sensor (R.H.) (code No.95).
Code No.93 Side impact sensor (L.H.) communication
system
This diagnosis code is output if communication between the side impact sensor
(L.H.) and the SRS–ECU is abnormal
MUT-II Self-diag code
Replace the side impact sensor (L.H.) with the side impact
sensor (R.H.) and then install them.
Connect the battery (–) terminal.
Erase diagnosis code memory.
Will the code No.93 disappear and show No.96?
Replacement of the side impact sensor (L.H.) installed at the
driver's side.
