 |   PERFORMANCE ORDER  |  |   1. Connect a voltmeter between terminal 30 (A) plug relay control heating and housing.  The meter should show the battery voltage (about 12 V).  |      |   2. Otherwise, check for an open red wire from the connecting block (X12 / 3) to the relay control heating.  |  |   3. Turn the ignition key to the warm-up and connect a voltmeter to the chip 1 (terminal 15) 6-pin plug and the housing.  Specification: battery voltage (about 12 V).  If pressure is absent, check for an open black / red wire from fuse 23 (unprotected side) to the plug, 1 chip.  |  |   4. Connect a voltmeter to the chip 1 (+ terminal 15) and the chip 4 (-, terminal 31).  Specification: battery voltage (about 12 V).  Otherwise, check for an open brown wire from 4 chips on the body.  |
