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.
