04-124 DIAGNOSTICS - REVERSE RADAR SYSTEM

Diagnostic steps

1 . Check reverse radar probe

(a) Ignition Switch: OFF.
(b) Disconnect left reverse radar probe connector B006.
(c) Disconnect right reverse radar probe connector B009.
04
(d) Replacement of new reverse radar probe. (Refer to Chapter 81. Information system -
reverse radar, replacement of reverse radar probe)
CAUTION

Replacement of new reverse radar probe shall be of the same size and model of the
old reverse radar probe
(e) Ignition Switch: ON.
(f) Place in reverse gear

Whether self-checking of the reverse radar is normal or not?
Yes> Replace reverse radar probe.
No> go to step 2

2 . Check harness and connector (reverse radar probe-ground)
(a) Ignition Switch: OFF.
(b) Disconnect left reverse radar probe connector B006.
(c) Disconnect right reverse radar probe connector B009.

(d) Measure the electrical resistance between
left reverse radar probe B006（4）、B009
（4）and the ground respectively.
Standard electrical resistance (check
whether there existent an open circuit)

Multimeter connection Standard value

B006（4） - ground
＜2Ω
B009（4） - ground

Check whether the result is normal?
Yes> go to step 3
No > Maintenance or replace harness.

3 . Check harness and connector (reverse radar controller-reverse radar probe)
(a) Ignition Switch: OFF.
(b) Disconnect left reverse radar probe connector B006.
(c) Disconnect reverse radar controller connector C035.
