Manual Road TestS7RS0B5104012
WARNING!
Carry out test in very little traffic area to prevent an accident.
Test requires 2 persons, a driver and a tester.

The purpose of this test is to judge whether causal factor of trouble which occurred in automatic transaxle is electrical
or mechanical by disconnecting valve body harness co nnector (1) and fixing automatic transaxle gear position.
1) Start engine and warm it up to normal operating temperature.
2) Turn ignition switch to OFF position and disconnect valve body harness connector (1).
3) Turn OFF all electrical loads. With select lever shifted to each ra nge (“L”, “2”, “3” and “D”), drive vehi cle at 1,000 rpm engine speed and then
check vehicle speed by referring to “Fixed gear position”.
If vehicle speed is not as specified in “Fix ed gear position” table, go to troubleshooting.
4) Connect valve body harness connector and clear DTC.

Precautions
Steering System NoteS7RS0B6300001
NOTE
All steering gear fasteners are important attaching parts in that they could affect the performance of
vital parts and systems, and/or could result in major repair expense. They must be replaced with one of
the same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of these parts.

Precautions in Diagnosing TroublesS7RS0B6300002
• Take a note of DTC indicated on the SUZUKI scan tool.
• Before inspection, be sure to read “Pre cautions for Electrical Circuit Service in Section 00” and understand what is
written there.
• DTC C1122 (engine speed signal failure) is indicated when ignition switch is at ON position and engine is not
running, but it means there is nothing abnormal if indica tion changes to a normal one when engine is started.
• As DTC is stored in memory of the P/S control module, be sure to clear memory after repair by performing the
procedure described in “DTC Clearance”.
