Airbag System

Code No.21, 22, 61, 62 Air bag module (Driver's side squib) system

[Explanation]

These codes are output when the resistance value between the air bag module (squib) terminals in the SRS-ECU is out of the normal range.

The probable causes of trouble associated with the respective code Nos. are as follows. (Refer to the chart 1.)

Probable cause of trouble

Defective clock spring

Defective harness, connector

Defective air bag module (Driver's side squib)

Defective SRS-ECU

CHART 1

Code No. - Probable cause of trouble

Code 21
^ Air bag module (Driver's side squib) or harness short-circuited
^ Clock spring short-circuited

COde 22
^ Air bag module (Driver's side squib) or harness open-circuited
^ Clock spring open-circuited
^ Connector in loose contact

Code 61
^ Harness of driver's side air bag module (squib) short-circuited to power supply

Code 62
^ Harness of driver's side air bag module (squib) short-circuited to ground
Caution

1. After the ignition switch has been placed at the LOCK position and the negative (-) terminal of the battery has been disconnected, wait for more than 60 seconds before starting work. Wind a tape around the disconnected (-) terminal for insulation.

2. Do not attempt to measure the air bag module (squib) circuit resistance. Use of a tester in measuring the circuit resistance will supply current to the squib, or erroneous deployment due to static electricity could cause serious injury.
