step 12.
12. Confirm the sleep mode:
-
Check for voltage to ground on the BRN wire and PNK wire. There should be battery voltage in the sleep mode.
-
Check the parasitic draw at the battery while shifting to sleep mode. Amperage should change from about 70 to 80 mA to less than 20 mA.
-
If the vehicle does not go into the sleep mode, carefully perform Mode 2 test (see step 14), and check for faulty input for example a key
cylinder switch keeping the system awake.
13. Confirm the wake up mode:
-
When any switch in the multiplex system is turned on, it wakes up its related control unit which, in turns wakes up, wakes up the other units.
After one minute it will return to sleep mode again if the switch is returned to the original position.
-
When the ignition switch is turned to ON (II), all of the multiplex control units wake up at the same time without "talking" to each other
through the communication lines.
If the wake up mode is confirmed on the first switch tested, and there is no problem with any other switch operation, the system is working
correctly. Go to step 14.
After confirming a problem in sleep mode, look in the following tables for the switch most closely related to the problem you may be having.
Operate that switch and see if its control units wake up. Also use Mode 2 step 14 to confirm switch inputs.
NOTE: If any control unit is faulty and will not wake up, several functions (locks, windows, etc.) of the system will malfunction at the same time.
